Air pollution in the United Kingdom

Air quality targets set by the Department for Environment, Food and Rural Affairs (DEFRA) are mostly aimed at local government representatives responsible for the management of air quality in cities, where air quality management is the most urgent. 

Published information[edit]

The UK has established an air quality network where levels of the key air pollutants[1] are published by monitoring centres.[2] Air quality in Oxford, Bath and London[3] is particularly poor. One controversial study[4] performed by the Calor Gas company and published in the Guardian newspaper compared walking in Oxford on an average day to smoking over sixty light cigarettes.

More precise comparisons can be collected from the UK Air Quality Archive[5] which allows the user to compare a cities management of pollutants against the national air quality objectives[6] set by DEFRA in 2000.

Localized peak values are often cited, but average values are also important to human health. The UK National Air Quality Information Archive offers almost real-time monitoring of "current maximum" air pollution measurements for many UK towns and cities.[7] This source offers a wide range of constantly updated data, including:

  • Hourly Mean Ozone (µg/m³)
  • Hourly Mean Nitrogen dioxide (µg/m³)
  • Maximum 15-Minute Mean Sulphur dioxide (µg/m³)
  • 8-Hour Mean Carbon monoxide (mg/m³)
  • 24-Hour Mean PM10 (µg/m³ Grav Equiv)

DEFRA acknowledges that air pollution has a significant effect on health and has produced a simple banding index system[8] that is used to create a daily warning system that is issued by the BBC Weather Service to indicate air pollution levels.[9] DEFRA has published guidelines for people suffering from respiratory and heart diseases.[10]

The Great Smog of 1952[edit]

Main article: Great Smog of 1952
The Great Smog of 1952 in London.

Early in December 1952, a cold fog descended upon London. Because of the cold, Londoners began to burn more coal than usual. The resulting air pollution was trapped by the inversion layer formed by the dense mass of cold air. Concentrations of pollutants, coal smoke in particular, built up dramatically. The problem was made worse by use of low-quality, high-sulphur coal for home heating in London in order to permit export of higher-quality coal, because of the country's tenuous postwar economic situation. The "fog", or smog, was so thick that driving became difficult or impossible.[11] The extreme reduction in visibility was accompanied by an increase in criminal activity as well as transportation delays and a virtual shut down of the city. During the 4 day period of fog, at least 4,000 people died as a direct result of the weather.[12]

April 2014[edit]

More areas of England warned of 'very high' air pollutions in April 2014. High levels of pollution in London and other parts of the south east of England may at worst days cause sore eyes and sore throats and experts warned those with heart conditions and asthma to stay inside.[13][14]
