pollutants are biodegradable and therefore will not persist in the environment in the long term. However, the degradation products of some pollutants...

and some plastics take many millennia to decompose. A standard for biodegradability used by the European Union is that greater than 90% of the original...

Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic...

Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. They...

is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living...

substances such as oil, metals, plastics, pesticides, persistent organic pollutants, and industrial waste products. Another is stressful conditions such as...

or lost into the environment as pollution. Almost all plastic is non-biodegradable and without recycling, spreads across the environment where it can...

Legacy pollution or legacy pollutants are persistent materials in the environment that were created through a polluting industry or process that have polluting...

Air Pollution Index, and Singapore's Pollutant Standards Index. Computation of the AQI requires an air pollutant concentration over a specified averaging...

removal of biodegradable organic matter and suspended solids. It uses air (or oxygen) and microorganisms to biologically oxidize organic pollutants, producing...

to test degradability, biodegradability, and non-toxicity, and with which a properly designed and manufactured oxo-biodegradable product must comply. These...

or being returned to the environment as biodegradable waste. This reduces the amount of (non-biodegradable) waste disposed, as recyclables are recovered...

Stockholm Convention on Persistent Organic Pollutants is an international environmental treaty, signed on 22 May 2001 in Stockholm and effective from 17...

on pavements and railways. They are similar to auxins and most are biodegradable by soil bacteria. However, one group derived from trinitrotoluene (2:4...

Non-exhaust emissions come from wearing down motor vehicle brake pads, tires, roads themselves, and unsettling of particles on the road. This particulate...

their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding...

for non-treated plants. Some natural, biodegradable compounds, such as exogenous polyamines, allow the plants to tolerate concentrations of pollutants 500...

observed that more microplastics might be formed from biodegradable polymer than from non-biodegradable polymer in both seawater and fresh water. There are...

Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more...
