Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. Ever since the beginning of the Industrial Revolution in the United States, America has had much trouble with environmental issues, air pollution in particular. According to a 2009 report, around "60 percent of Americans live in areas where air pollution has reached unhealthy levels that can make people sick".[1] Pollution in the United States has plummeted in the recent decade, with pollutants such as nitrogen dioxide decreasing despite the fact the number of vehicles on the road isn't. This is due to better regulations, economic shifts, and technological innovations. With respect to nitrogen dioxide, NASA reported a 32% decrease in New York City and a 42% decrease in Atlanta between the periods of 2005-2007 and 2009-2011. Air pollution can cause a variety of health problems including, but not limited to infections, behavioral changes, cancer, organ failure, and even premature death. These health effects are not equally distributed in terms of race, ethnicity, socioeconomic status, education, and more in the United States. Also, multiple policies and policy changes proposed by Trump administration will cause environmental damage and increase air pollution in the United State. California has the worst air quality of any state, and in most surveys the cities in California rank in the top 5 or top 10 of most polluted air in the United States.[2][3]
Clean Air Acts
In the 1960s, 1970s, and 1990s, the United States Congress enacted a series of Clean Air Acts which significantly strengthened regulation of air pollution. Individual U.S. states, some European nations and eventually the European Union followed these initiatives. The Clean Air Act sets numerical limits on the concentrations of a basic group of air pollutants and provide reporting and enforcement mechanisms.
In 1999, the United States Environmental Protection Agency (EPA) replaced the Pollution Standards Index (PSI) with the Air Quality Index (AQI) to incorporate new PM2.5 and Ozone standards.
The effects of these laws have been very positive. In the United States between 1970 and 2006, citizens enjoyed the following reductions in annual pollution emissions:[4]
- carbon monoxide emissions fell from 197 million tons to 89 million tons
- nitrogen oxide emissions fell from 27 million tons to 19 million tons
- sulfur dioxide emissions fell from 31 million tons to 15 million tons
- particulate emissions fell by 80%
- lead emissions fell by more than 98%
In an October 2006 letter to EPA, the agency's independent scientific advisors warned that the ozone smog standard “needs to be substantially reduced” and that there is “no scientific justification” for retaining the current, weaker standard. The scientists unanimously recommended a smog threshold of 60 to 70 ppb after they conducted an extensive review of the evidence.[5]
The EPA has proposed, in June 2007, a new threshold of 75 ppb. This is less strict than the scientific recommendation, but is more strict than the current standard.
Some industries are lobbying to keep the current standards in place. Environmentalists and public health advocates are mobilizing to support the scientific recommendations.[citation needed]
International pollution
An outpouring of dust layered with man-made sulfates, smog, industrial fumes, carbon grit, and nitrates is crossing the Pacific Ocean on prevailing winds from booming Asian economies in plumes so vast they alter the climate. Almost a third of the air over Los Angeles and San Francisco can be traced directly to Asia. With it comes up to three-quarters of the black carbon particulate pollution that reaches the West Coast.[6]
In the United States unhealthy levels of pollution are measured by the Environmental Protection Agency and independent researchers or agencies, like the American Lung Association. Federal limits and pollution standards are set by the Clean Air Act.
Health effects
Asthma
As air pollution increases, symptoms of asthma worsen. Asthma's etiology is poorly understood and currently has no cure. There are many environmental factors that attribute to asthma. The main sources of environmental pollution are the burning of fossil fuels in the combustion engines, dust generated by traffic on road surfaces, and biomass used for cooking and heating. In urban areas, there are high concentrations of particulate matter, nitrogen dioxide, ozone, and other volatile organic compounds and can make breathing more difficult. Young children who are exposed to air pollution are extremely vulnerable. One reason they are more vulnerable is because the average breathing pattern for an adult is 16 to 20 breaths per minute, while a 1-year-old child has a faster breathing pattern which is 20 to 40 breaths per minute. Therefore, children will be inhaling more pollutants than adults.[7]
Prenatal Exposure and links to asthma
Prenatal exposures to air pollution have influenced respiratory health starts in utero.[8] Mothers who were exposed to PM2.5 weekly during gestation, were likely to have a child diagnosed with asthma by the age 6 years. Many of the mothers exposed to PM2.5 were ethnic minorities (54% Hispanic, 30% black), had 12 or fewer years of education (66%), and did not smoke in pregnancy (80%).[8] Inner-city children from the age of 5–11 Yyears old were dignosed with Asthma, due to prenatal exposure to phthalates, butylbenzyl phthalate (BBzP), di-n-butyl phthalate (DnBP), di(2-ethylhexyl) phthalate (DEHP), and diethyl phthalate (DEP). These phthalates were detected in urine samples from 300 pregnant women. [9]
Roughly seven million children suffer from asthma, meaning 1 out of every 10 children, and the rates have been steadily increasing. Among African American children, one out of six children suffer from asthma, which has rose from 50% since 2001. This issue of respiratory problems accounts for 88% of premature deaths in low-income to middle-class counties in America.[10] Population-based studies have shown that communities with a high proportion of African Americans and Hispanics experience high rates of asthma.
Exposures to Airborne Particulate Matter Components in New York
In a study conducted by Yale University, 'Environmental Inequality in Exposures to Airborne Particulate Matter Components in the United States’, Hispanics were exposed to 10 out of the 14 pollutants (e.g., 152% higher than whites for chlorine, 94% higher for aluminum), African Americans were exposed to 13 out of the 14 pollutants (e.g., 43% higher for zinc, 25% for vanadium), and Asians had higher exposures than whites (e.g., 103% for chlorine, 69% for vanadium, 64% for nickel). Some of the pollutants studied have been connected to asthma. In Bronx, New York, 66% of individuals who live in proximity of hazardous industrial facilities and waste sites are likely to be hospitalized for asthma. It has been reported that people who live within 1.86 miles of toxic waste facilities in the United States are people of color and twice as likely as white residents to live within a fence line zone of an industrial facility, contribute to air pollution, safety issues, and health concerns.[11]
Heart Disease
In the United States, cardiovascular disease kills a person every 40 seconds.[12] While the effects of air pollution on the respiratory diseases are well understood, air pollution also affects the cardiovascular system at the same level as or higher level than the respiratory system,[13] and the adverse cardiovascular health outcomes in both children and adults are high when exposed to air pollution. Carbon monoxide, oxides of nitrogen, sulfur dioxide, ozone, lead, and particulate matter are also associated with increased hospitalization and mortality due to cardiovascular disease. Chromosomal damage is high among African American children and their mothers from Oakland, California who are exposed to traffic and regional ozone levels.[14] Coronary heart disease has been one of the leading cause of death in ethnic groups.[15] One study found that PM2.5 exposure increases the risk of cardiovascular diseases by 13%. Also, those who live in the area of lower socioeconomic status have higher risk of cardiovascular diseases caused by PM2.5 exposure.[16]
Indoor air pollution, caused by kerosene space heaters, cooking, wall paints, second hand smoke and more, are also known to have an association with the cardiovascular diseases.[17][13] This increased risk of cardiovascular diseases by indoor air pollution disproportionately affects the people in the United States. The prevalence of being exposed to secondhand smoke is higher in African American population and lower income population, especially in those who live below the poverty level.[18] On the other hand, the risk of fatal cardiovascular diseases is higher in African American men and women than white men and women. For example, 25% of African American men have 6.67% or greater increased risk of fatal cardiovascular disease while only 10% of the white men have the same level of increased risk.[19] Furthermore, one county-level study found that median income and education level were the most significant factors associated with the cardiovascular diseases mortality disparities in the United States.[20]
Infection and cancer
Exposure to air pollution increases the risk of developing respiratory infections and cancers. Inhaled air pollutants damage the respiratory system and can lead to infections or cancer. Respiratory infections and cancer are related to each other. Having a respiratory infection raise the risk of cancer and vice versa.[21] Also, studies show that the risk of the respiratory infections and cancers caused by air pollution are not distributed equally in terms of race, class, and geographic placement.
Infections
Even though the mechanistic association between air pollution and infections is still unclear and require further research,[22] some studies shows that the some air pollutants, including secondhand smoking, ozone (O3), particulate matter (PM), and nitrogen dioxide (NO2), may cause the infections[22][23]. According to the Consumer Product Safety Commission (CPSC), children have higher risk of lower respiratory tract infections, such as pneumonia and bronchitis, if their parents smoke. CPSC mentions that 150,000 to 300,000 children (under 18 month) are affected by the lower respiratory tract infections which leads to 7,500 to 15,000 hospitalizations each year based on the EPA estimation. Exposure to higher level NO2 or long term exposure to low level NO2 also leads to higher risk for infections.[24]
Biological air pollution also can lead to the infections. Small, invading organisms in human body, such as bacteria, viruses, fungi, or parasites, can cause infections in the pulmonary system. There are variety of infections because many different organisms can cause the infections.
The prevalence of the bacterial infections is not equally distributed interms race and socieconomic status. In the United States, bacterial pneumonia, caused by Streptococcus pneumoniae bacteria (pneumococcus) which enters human body usually via inhalation,[25] is significantly associated with morbidity and mortality among adults. The risk of being diagnosed with bacterial pneumonia is more than double in African American people compared to white people (RR= 2.40). Also the prevalence of bacterial pneumonia in most impoverished African American census area, 20% or more people in the area live below the federal poverty level, is 4.44 times higher than the least impoverished white census area, less than 5% of the population in the area live below the federal poverty level, and 2.12 time higher than most impoverished white census area.[26]
Cancer
Many studies found that both indoor and outdoor air pollution can increase the risk of respiratory cancer. Indoor pollution such as tobacco smoking is responsible to lung cancer. Outdoor air pollution also increases the risk of lung cancer.[27] A study found that the combination of formaldehyde and benzene is responsible for 60% of cancer related health problems in the United States. Air pollutants can also cause other types of cancer. Another study found that the hazardous air pollutant (HAP) can cause cervical cancer and the upper aero-digestive tract cancer.[28]
The cancer caused by air pollution is not equally distributed in the United States. Cancer incidence and death rates are higher in African Americans than other races. A study conducted in Greater Houston, Texas shows that Hispanics and African-Americans have higher risks of HAP cancer. People who live near the public transit exhibit have higher HAP cancer risk as well.[29] Furthermore, another study shows that highly segregated metropolitan areas have higher estimated cancer risk caused by the air pollution. This trend was found for all racial groups, but was the strongest for for Hispanics.[30]
A study conducted in 2000 used geographic census data and outdoor nitrogen dioxide (NO2) concentration data to examine the disparities of NO2 air pollution across the United States. The study found that there is disproportional disparities in terms of both race and socioeconomic groups. The people of color were exposed to 4.6 ppb more than average NO2 concentrations than white people. Those who live in below poverty level are exposed to 1.2 ppb more. Lower-income Caucasians are exposed to 3.4 ppb higher NO2 concentrations than the higher-income Caucasians. The study also reports disproportional disparities of NO2 concentration exposure by education level; those who without high school education are more likely to be exposed to higher concentrations.[31] Association between NO2 exposure and cancer development has been found in many studies.[32]
The disproportional effects of air pollution on people’s cancer risk is seen not only in race difference. Within a single race community, there is unequal distribution of cancer risks. Among the Hispanic population in Miami, Florida, the traffic-related cancer risks are unequally distributed in terms of socioeconomic levels and country of origin. The Hispanic community with lower incomes are more likely to have higher traffic-related cancer risks. Also, it was found that Hispanics originally from Cuba and Colombia have higher risk of cancer caused by the traffic related toxins.[33]
Central nervous system
Air pollution is traditionally associated with pulmonary problems, but it also affects the entire body. Nano-sized pollutants can enter the body by penetrating pulmonary tissue after it is inhaled and enter the blood stream via capillaries. Once inside the circulatory system, the heart will spread the pollutants throughout the body. One of the places these pollutants accumulate and affect is the brain and nervous system. The brain is constantly changing and growing throughout a person’s lifetime by reorganizing its synaptic connections in regards to its changing environment.[34] Therefore, presence and buildup of toxic pollutants in the brain can lead to health problems, diseases, and behavior changes[35] and people living in communities with poor air quality, usually low income, and colored communities, have higher chances of becoming ill than wealthy, white communities.
Brain Development
It is found that children living in areas of high air pollution, particularly high traffic pollution, tend to do worse on standardized testing. Black carbon is very small (PM2.5), very light absorbent pollutant that mostly comes from incomplete combustion of fuels.[36] According to a study in 1986–2001 in Boston, children who were exposed to more black carbon did worse on the standardized tests they were given (Wide Range Assessment of Memory and Learning and the Kaufman Brief Intelligence Test) in all subjects. In the study, there was also association found between increased black carbon levels, worse testing results and children who primarily spoke Spanish at home and have parents with lower education.[37] A similar study conducted was conducted on inner New York City children. This time, the study looked at polycyclic aromatic hydrocarbons (PAH) (PM2.5) which is found in coal, tar, and incomplete combustion emissions. All of the children in the study were African American or Dominican and it was found that they have lower mental development index (MDI) scores and greater chances of having cognitive developmental delay than their Caucasian counterparts living in less polluted parts of the city.[38]
Other health problems
Air pollution components such as heavy metals and reactive oxygen species can cause central nervous system health problems ranging from neuroinflammation to short term memory disturbances to Parkinson’s.[35] Particulate matter (PM), especially ultrafine particles (UFPM), that make its way up to and stay around the brain also become pro-inflammatory stimulus. This stimulus also leads to neuroinflammation. Human and animal studies show that neuroinflammation leads to neurodegenerative diseases.[35] A study showed that residents aged 54.7 ± 4.8 years from highly polluted cities have significantly higher gene expression for an inflammatory gene in their brain than residents in the same age group from less polluted cities.[38] Though the mechanisms on how PM causes neuroinflammation, many studies hint that it there’s correlation between air pollutant caused neuroinflammation and development of Parkinson’s Disease and Alzheimer Disease.[33]
Ozone-Related problems
Ozone is produced by naturally and artificially (vehicles, refineries, plants, etc.). It is a very strong oxidizing agent and when inhaled, it attacks tissues by modifying parts of cells and it can create potentially toxic by products.[39] It was found that there is no correlation between ozone effects estimates for mortality and PM readings of an area. In other words, damage done by ozone and by PM cannot be considered the same.[40] Extended periods of inhaling ozone causes neuron damage and death, motor deficits, and memory deficits in humans and animals.[35] Certain groups, such as African Americans, have higher chance of having ozone-caused health issues because of their higher ozone exposure.[41] A study conducted in Los Angeles, CA showed that there is a 12-15% increase in chance for a child to be born with or develop autism if the parents lived in areas with high ozone concentration during the child's gestation period. From the hospital records, it was found that majority of those parents were also Hispanic and were low income families. There were less autistic children born in majority white, highly educated, and high income communities.[40] The same study also found that higher levels of nitrogen dioxide (NO2) and nitric oxide (NO), both can undergo chemical reactions to form ozone, also can increase the chance of Autism in a child.
Disparities in the effects of air pollution
The health consequences of air pollution are often distributed unequally amongst a given area's population, and can disproportionately impact certain groups of people with greater severity than others. Because of this, much research has been devoted to discerning the determinants of increased exposure to pollutants. Three factors strongly correlated with increased risk include: race and ethnicity, socioeconomic status, and education. The underlying cause of this inequality may involve a multitude of systematic injustices which dictate exposure to harm or access to healthy environmental conditions.[42] This concept is known as environmental justice.
Race and ethnicity
In particular, people of color can be more vulnerable to the detrimental effects of air pollution.[42] Studies have revealed that people of color experience significant disparities in income distribution than their white counterparts.[43] Therefore, many communities of color reside in impoverished neighborhoods and face unequal access to environmental health services and resources.[1]
Environmental racism
Environmental racism is the academic term that describes how certain environmental injustices can be viewed as discriminatory towards communities of racial minorities. The term highlights any disproportionate exposure to toxins or inaccessibility to ecological benefits such as clean water, clean air, and natural resources. Also, environmental racism is concerned with situations in which the government and large corporations target minority communities in order to commence environmentally damaging projects. They find that in these communities, there is often much less resistance and pressure to terminate these projects. When these projects are undertaken, nearby households and small businesses in these minority communities are negatively affected, sparking health problems among children and an overall decrease in the standard of living.
According to the 2014 Census, the median household income for both African-Americans and Hispanics was about $43,300. On the other hand, white household income was around $71,300. Also, over 91% of African-Americans and 86% of Hispanics live in urban areas, whereas only about 70% of whites live in urban areas.[44] Furthermore, in April 2017, three environmental groups—Environmental Justice and Health Alliance for Chemical Policy Reform, Coming Clean, and Center for Effective Government—completed a study regarding the disproportionate spread of environmental burdens. They define "fenceline zones" as areas within the vicinity of U.S. chemical facilities that are at of highest risk of death or injury after a potential chemical accident. They found that the 134 million people living in "fenceline zones" are 75% more likely to be African-American, 60% more likely to be Latino, and 50% more likely to be classified as having low socioeconomic status. The study was meant to not underline the idea that the United States government fails to justly protect its communities and but also to push the government to update chemical safety regulations nationwide. These factors greatly contribute to the fact minority exposure to harmful air pollutants ranges from 40% to 60% higher than whites-- evan as air quality is slowly improving as a whole.[45]
Socioeconomic status
Socioeconomic Status (SES) is an individual's or group's sociological and economic status in society.[46] Low socioeconomic status can correlate to a greater risk of exposure to unsafe and unhealthy conditions. People of lower socioeconomic statuses have an unequal access to resources and safety measures while people of higher socioeconomic statuses have a greater access to health and safety resources/measures.[47]
Impact of low SES and air pollution on health
People of lower socioeconomic status may more frequently have poor health, thus the effects of air pollution can incur additional health risks and shorter lifespans on this population.[48]
In the United States, racial and ethnic minorities, defined as people of color who represent a small portion of the overall population, are socioeconomically disadvantaged, and have a history of past discrimination.[49] There are four recognized minority groups in the United States: Asians and Pacific Islanders, African Americans, Hispanics, and Native Americans. Those of low socioeconomic status and people of color are more vulnerable to the short term and long term effects of air pollution.[50] Short-term health effects of air pollution include but is not limited to bronchitis or pneumonia, frequent headaches, dizziness, and nausea. Some long term health effects are lung cancer and respiratory diseases, heart disease, and organ damage, and irreversible nerve damage.[51]
People of lower socioeconomic status are found to be more vulnerable to air pollutant, PM 2.5, due to their location. PM 2.5 is an air pollutant, arising from the blend of power plants, refineries, and diesel engines, among other sources, and this particle penetrates the lungs.[52] Communities of low socioeconomic statuses are frequently concentrated in areas near highways, busy roads, and refineries. Therefore, limiting one's exposure to air pollution in an impoverished environment is nearly impossible. Communities of low socioeconomic status face an unequal access to environmental health services and resources.[53]
Factors of environmental disparities due to low socioeconomic status
They generally divide into three categories:
- Sociopolitical explanations in which hazardous facilities located in communities where they lack political capital to influence discussions
- Market-based explanations in which people who live in polluted areas have lower property value
- Racial discrimination in the placement of hazardous facilities.[54]
Education status
In many ways, the socioeconomic status determines the education level that a person can achieve.[55] According to literature, there is a lower rate for students from low socioeconomic status communities to get access to higher level of education compared to the students from more affluent communities.[56] Further studies have indicated that there is a significant correlation between income and educational attainment.[57] Therefore, even though education may not have a direct correlation with the exposure to the environmental injustice, it can still be an indirect indicator of the disparity in the distribution of environmental burden. [58]
Environmental injustices and the Trump Administration
Implications on Clean Power Plan
The Clean Power Plan is a policy designed by the Obama Administration to lower the levels of carbon dioxide emitted by power plants in the United States. The major estimated positive externalities of the plan include the reduction of air pollutants by up to 25% and the elimination of serious health altercations for those who live near factories and chemical facilities that emit carbon dioxide such as a considerable decrease of premature deaths and asthma attacks among children. Also, although steel, cement, and refining production jobs are likely to decrease on a large scale, this is expected to be counteracted by a boom in production and job opportunities in the solar and wind power sectors.
The plan was unveiled on August 3, 2015, but the continuation of the plan is now in question as the Trump Administration is expected to eliminate the policy during Donald Trump’s presidency. On March 28, 2017, President Donald Trump began the fist steps to eliminate the Clean Power Plan as he signed an executive order that mandated the Environmental Protection Agency to review the plan and its policies.[59]
Restrictions on the Environmental Protection Agency
Environmental racism can be defined as any practice of environmental injustice that disproportionately affects minority neighborhoods and communities. Not only is the California population incredibly racially diverse, but because California is the primary air polluter and consequently spends extra time, money and resources to develop technologies that ensure air pollution doesn't become detrimental to the environment, its climate policy is one of the most technologically important in the developed world. As of March 2017, the Trump Administration is expected to withdraw the federal waiver that gives the Environmental Protection Agency and California the power to efficiently monitor and regulate greenhouse-gas pollution from car tailpipes. Environmental agents and environmental rights activists foreshadow that this action will certainly spell trouble for California's important climate policy; as well as further worsen the disproportionate spread of negative environmental health problems to neighborhoods of color throughout counties in California statewide.[60]
The Paris Agreement
Donald Trump has suggested that the Trump Administration is pushing for the United States to exit the Paris Agreement, which is an agreement created on December 12, 2015 within the United Nations Framework Convention on Climate Change to regulate greenhouse gases worldwide. The Paris Agreement creates policies and regulations for the sustainable development of all regions of the globe with aims of developing technologies that will significantly lower greenhouse gas emissions worldwide as well as increase the abililty of all nations to adapt to the multiplying effects of climate change. As of April 2017, 195 countries have signed the agreement and 143 countries have ratified it, already adopting certain policies called upon by the treaty. European Union energy officials are genuinely expressing their concerns that the United States will exit the agreement and are convinced that this action will have substantial negative impacts on the state of the global environment. [61]
Energy Independence Executive Order
The Energy Independence order was issued by the Trump Administration in order to designed to promote energy resources and economic growth by cutting regulation burdens on energy production such as coal, natural gas, nuclear material, flowing water, and other domestic sources, including renewable sources. To ensure that the Nation's electricity is affordable, reliable, safe, secure, and clean, all agencies are to respect their the proper roles of the Congress and the States concerning these matters in our constitutional republic. Environmental regulations must comply with the law, are of greater benefit than cost for the American people, and are developed through the best available peer-reviewed science and economics.[62]
Revival of the Coal Industry
Trump promised to revive the coal industry and bring back coal-related jobs.[63] To fulfill his promise, on February 16, 2017, Trump signed a bill undoing the Stream Protection Rule signed during the Obama administration. This bill originally helped prevent coal mining from polluting waterways.[63] Burning coal produces air pollutants such as nitrogen oxides (NOX), sulfur dioxide (SO2), particulate matter (PMX), Black carbon, and smog. Increase of coal usage would greatly increase air pollution especially in areas surrounding the facilities many of which are located in communities of color and low-income.[64]
Environmental Health Education
The education status here does not merely refer to the educational background or the highest degree people have earned, but more importantly, the environmental health education. Generally, the population with less education are more likely to be exposed to the impact of air pollution.[65] For example, in the United States, people with a high school degree had 6.2% higher estimated exposure to PM 2.5 compared to those with a college degree. In addition to PM 2.5, people with a high school degree or lower are estimated to have at least 10% more exposure to Al, Ca, Cl, EC, SI, TI, V, and Zn when compared to people with a college degree.[66] Therefore, environmental health education could be one of the most effective approaches to raise the public awareness of the environmental issues.
Before 2017, the EPA have spent more than $8.7 million on environmental education annually to increase public knowledge and awareness about the current environmental issues and the consequences.[67] They aim to promote the popularization of the necessary skills and knowledge for the public to make decisions and participate in activities that lead to the resolution of environmental challenges.[68]
As of March 2017, the EPA budget have been severely impacted the condition of environmental education.[69] The 2018 United States federal budget cut approximately $2.5 billion from the roughly 8 billion annual budget for EPA, and the budget for environmental education was cut from $8.7 million to $0.555 million, which is reduced by 94%.[70]
Air pollution in California
California's air is the most polluted in the U.S.A.[71]
Los Angeles Air pollution
Los Angeles has some of the most contaminated air in the country. With a population of roughly over 10 million, the Los Angeles area is a large basin with the Pacific Ocean to the west, and several mountain ranges with 11,000-foot peaks to the east and south. Diesel engines, ports, motor vehicles, and industries are main sources of air pollution in Los Angeles. Frequent sunny days and low rainfall contribute to ozone formation, as well as high levels of fine particles and dust.[72]
Air pollution in Los Angeles has caused widespread concerns. In 2011, the Public Policy Institute of California (PPIC) Survey on Californians and the Environment showed that 45% of citizens in Los Angeles consider air pollution to be a “big problem”, and 47% believe that the air quality of Los Angeles is worse than it was 10 years ago.[73] In 2013, the Los Angeles-Long Beach-Riverside area ranked the 1st most ozone-polluted city, the 4th most polluted city by annual particle pollution, and the 4th most polluted city by 24-hour particle pollution.[74]
Both ozone and particle pollution are dangerous to human health. The Environmental Protection Agency (EPA) engaged a panel of expert scientists, the Clean Air Scientific Advisory Committee, to help them assess the evidence. The EPA released their most recent review of the current research on health threat of ozone and particle pollution.[39][75]
EPA Concludes Ozone Pollution Poses Serious Health Threats
- Causes respiratory harm (e.g. worsened asthma, worsened COPD, inflammation)
- Likely to cause early death (both short-term and long-term exposure)
- Likely to cause cardiovascular harm (e.g. heart attacks, strokes, heart disease, congestive heart failure)
- May cause harm to the central nervous system
- May cause reproductive and developmental harm
- U.S. Environmental Protection Agency, Integrated Science Assessment for Ozone and Related Photochemical Oxidants, 2013. EPA/600/R-10/076F.
EPA Concludes Fine Particle Pollution Poses Serious Health Threats
- Causes early death (both short-term and long-term exposure)
- Causes cardiovascular harm (e.g. heart attacks, strokes, heart disease, congestive heart failure)
- Likely to cause respiratory harm (e.g. worsened asthma, worsened COPD, inflammation)
- May cause cancer
- May cause reproductive and developmental harm

Helping the area to meet the national air quality standards and improve the health of local residents continues to be a priority for the EPA. One of EPA's highest priorities is to support the reduction of diesel emissions from ships, trucks, locomotives, and other diesel engines.[74] In 2005, Congress authorized funding for the Diesel Emissions Reduction Act (DERA), a grant program, administrated by the EPA, to selectively retrofit or replace the older diesel engines most likely to impact human health. Since 2008, the DERA program has achieved impressive out outcome of improving air quality.[76] The EPA also works with state and local partners to decrease emissions from port operations and to improve the efficient transportation of goods through the region. Both the EPA and the Port of Los Angeles are partners of the San Pedro Bay Ports Clean Air Action Plan, a sweeping plan aimed at significantly reducing the health risks posed by air pollution from port-related ships, trains, trucks, terminal equipment and harbor craft.[72] For environmental justice, air pollution in low-income LA communities has received more attention. In 2011, the “Clean up Green up” campaign was launched to designate four low-income LA communities- Pacoima, Boyle Heights and Wilmington. This campaign aims to push green industries through incentives, including help obtaining permits and tax and utility rebates.[77]
Although Los Angeles air pollution level has declined for the last few decades,[78] citizens in Los Angeles still suffer from high level air pollution.[79]
Air Pollution and Low SES Communities in California
The U.S. Environmental Protection Agency's interactive online map - EJSCREEN - features the low socioeconomic communities across the country that are more vulnerable to air pollution and its associated health risks. As exhibited in this map, Southeast Los Angeles County neighborhoods, primarily impoverished areas in the San Joaquin Valley and Inland Empire, face a higher exposure to air pollution and environmental injustices. In such areas, those in poverty stricken areas have an unequal access to environmental health and safety resources. These poverty-stricken neighborhoods are frequently located in areas that are near freeways, hazardous facilities, and/or rail yards.[80]
Instances of environmental injustice
Diabetes in Los Angeles County Latin(x) children
In 2017, researchers found that diabetes in Latin(x) children living in Los Angeles is linked to air quality.[81] A study led by the University of Southern California was the first of its kind to follow the health and residential air pollution levels of the same children over a span of several years. The subjects of the study were overweight Latin(x) children, between the ages of eight and fifteen, residing in areas with excess particulate matter. In particular, the neighborhoods of the children were located in areas of elevated nitrogen dioxide levels, an air pollutant caused nearby power plants and high-volume vehicle traffic.[81] The results demonstrated that the children possessed significantly increased risk factors for Type 2 diabetes by the time they turned eighteen, such as diminished efficiency in the insulin-secreting cells of the pancreas.[82] The insulin resistance that results from such a condition is a direct cause of diabetes onset.[83]
Diabetes mellitus is a disease that is characterized by the body's inability to properly regulate blood glucose (or blood sugar) levels. Prolonged levels of high blood sugar may lead to severe health complications such as heart disease, nerve damage, kidney failure, blindness, or even early death.[84] As diabetes becomes a rising epidemic, the Center for Disease Control and Prevention estimates that up to nearly 8 million U.S. citizens may have undiagnosed diabetes or its precursor.[85] Conventional medical findings suggest that unhealthy or calorie-dense diets, lack of physical activity, and family history are risk factors for developing the disease; however, recent studies are beginning to trace a connection between Type 2 diabetes and the external factor of air pollution.[82] Because socioeconomic status, race, and exposure to air pollution are frequently correlated, the CDC acknowledges certain socioeconomic conditions or races as pre-existing risk factors for Type 2 diabetes, in addition to those previously listed.[81] Statistics suggest that hispanic people are 50% more likely to die from diabetes than whites, and studies focusing on issues of environmental injustice are able to demonstrate possible reasons for this disparity.[86]
Proximity of schools to vehicle traffic in Culver City
The spatial arrangement of Californian communities plays a large role in determining exposure to the concentrated air pollution of the state's southern regions. In one suburb of Los Angeles, El Marino Language School sits adjacent to the ten-lane Interstate 405. Students of schools like these, often elementary-aged, are subject to dramatically increased levels of pollution from automobile emissions, including carcinogenic compounds.[87] Health effects of traffic pollution include the onset of cardiovascular disease, asthma, impaired lung function, premature death, and a plethora of other complications.[88] Furthermore, the incomplete development of childrens' sensitive respiratory systems leads to compounded effects of air pollution when compared with the health effects of the same pollution on adults.[89]
Though the health consequences of vehicle pollution are widely recognized and some legislation has been enacted to reduce its impact, very little tangible action has actually been taken. In 2003, California passed Senate Bill No. 352, which banned the construction of new schools within 500 feet of freeways with certain exceptions.[90] However, the bill remained largely ignored as 1 in 5 schools opened between 2014 and 2015 were still in direct violation of the ban.[87] In 2015, the Environmental Protection Agency released a report titled "Best Practices for Reducing Near-Road Pollution Exposure at Schools", available both online and in-print.[89] However, without any requirements regarding school siting from the U.S. Department of Education, state-funded schools are under no obligation to follow its guidelines. The reluctance of public schools to comply with safety regulations often stems from monetary limitations that encourage the use of cheap land, a dilemma that disproportionately impacts children of poorer areas; the report noted that minority and low-income students have a higher prevalence of attendance in public schools of urban areas, such as the big cities in which busy roads and schools share territory.[87]
Fracking violations in Kern County school zones
Oil fracking is a process that involves a high pressure injection of fluid into the ground to extract oil.[91] The adverse environmental effects of this natural gas extraction are the subject of much controversy, the primary concerns of which surround the contamination of surrounding water and air sources. These risks result when underground drinking water and surface water are exposed to discharges of the chemically-infused fracking fluid due to faulty construction or operation, disposal leaks, or other unintended byproducts like the release of hazardous volatile compounds into the air.[92] In terms of air pollution, "hydrofracking" causes detriment to both the environment and human health. Enormous quantities of methane, a greenhouse gas, escape into the ozone layer of Earth's atmosphere during the extraction process, where they accelerate the impacts of climate change. Furthermore, air contaminants like nitrogen oxides, carbon monoxide, formaldehydes, and hydrogen sulfide that are released during drilling have been shown to cause harmful effects ranging from cancer, organ failure, neurological issues, to birth defects.[93]
In 2015, a study revealed that there are forty-five fracking sites within 1.5 miles of one junior high in the town of Shafter, one of California's top ten most polluted communities. The students of this community suffer from the state's decision to allow oil companies to continue hydraulic fracturing within close proximity of their schools. Parents observe severe and unexplainable health complications amongst their children, including asthma and epilepsy, that may be correlated with air toxins from the nearby wells.[94] In all of Kern County, in which Shafter is located, a staggering ten school districts sit within one mile of fracking wells. The situation becomes even more problematic when the fact that Kern County is predominantly Latin(x) in racial/ethnic composition is considered; in fact, 20% or more of its residents are foreign-born emigrants of Asia and Latin America.[93] Some argue that the concentration of fracking sites around the community's population of color is a discriminatory practice in direct violation of California Code 11135, which states that no person shall be unlawfully subjected to discrimination by any state or state-funded agency on the basis of race or ethnic group identification.[95]
Inequalities in cumulative environmental burdens among three urbanized counties in California
In 2012, this research used the method of cumulative environmental hazard inequality Index (CEHII), which is a model developed to environmental inequality in air pollution hazards., to analyze the environmental inequality in three counties in California: Alameda, San Diego and Los Angeles (Jason et al. 2012). In addition to frequently used air pollution parameter like NO2, PM 2.5 and diesel PM, a metric of heat stress was included for the analysis because excessive heat weather comes to be an environmental problem that can threaten human health.
The result indicated that color community bear greater air pollution including NO2, PM 2.5, PM 10, and heat stress compared to predominantly white and more affluent community. In San Diego County, the relative heat stress inequality was founded to be the highest. Also, significant heat stress inequality was observed in Los Angeles. The result shows that in these two counties, there was a strong positive correlation between the percentage of Non-Whites in the community and heat stress inequality. However, in Alameda county, the result indicated an opposite pattern which indicates. The community with a higher White population experience more extreme temperature exceedances. This might be explained by the fact that White population and the more affluent class in Alameda County mainly lived in the eastern area further away from the coast, which resulted in the higher heat stress exposure.
Also, the research verified that poverty status is consistent with the trend of disproportion burden of the racial-ethnic status. As the analysis was conducted according to the poverty status instead of racial-ethnic status for air pollutants NO2, PM2.5, and diesel PM, the results indicated the similar result as the analysis to heat stress. Furthermore, from our data, we found a strong correlation between poverty and proportion of non-white population (Alameda: r=0.69, Los Angeles: r=0.77). After all, this research demonstrates that the air pollution is disproportionally distributed according to the socioeconomic and racial-ethnic status in the United States.
As a future direction of study, it plans to classify the inequality exists in African American, Hispanic, Asian, and other ethnic groups. Furthermore, the technique used in this research provided a way to assess environmental inequality and the results can be used to assist decision makers in efforts to address environmental inequality issues.[96]
Proposed coal terminal expected to harm minority communities in West Oakland
In February 2016, the city of Oakland publicly announced construction plans of Oakland Bulk and Oversized Terminal in West Oakland. West Oakland is a predominantly Latino and African-American community, and its residents already live in a community that suffers from dangerous levels of air pollution. According to the Toxic Wastes and Race in the United States report issued by the East Bay Community Foundation, those living in West Oakland encounter five times more toxic pollution per person than residents of the city of Oakland and children living in West Oakland are seven times more likely to be hospitalized for asthma than the average child in California. Thousands of Oakland residents and environmental rights activists worked together to prevent the construction of the coal terminal and in July 2016, Oakland City Council voted to ban coal from being handled and stored in the City of Oakland.[97]
