Importance of air quality and its significance
Dudley’s air quality has improved dramatically since the 1950s when ‘clean air’ legislation was introduced to prevent air pollution episodes created by heavy industry and from the burning of coal. However, air pollution is still an issue today and poor air quality can affect health and everyday quality of life.
Nowadays the main sources of pollution in Dudley are emissions from road transport (including lorries, buses and cars). Petrol and diesel motor vehicles emit a wide variety of pollutants, principally carbon monoxide (CO), oxides of nitrogen (NOx), volatile organic compounds (VOCs) and particulates (PM10), which have an increasing impact on urban air quality. High levels of pollution tend to be associated with busy main roads and junctions.
