Studies have shown that exposure to air pollution, particularly particulate matter, is harmful to your health. Exposure to air pollution has been linked to increases in hospital admissions and mortality related to respiratory illness and diseases. A World Health Organisation (WHO) study suggested that particular matter air pollution reduced the life expectancy of Europeans by 8.6 months, and that reducing this air pollution would save up to $161 billion euros.
Air pollution is usually measured outdoors and usually measures point sources of pollution, such as factories, or linear sources, such as high volume roads. Yet most of our time is spent indoors where our air quality is affected by other sources of pollution such as smoking, gas burners, mold, and VOC's.
The US Environmental Protection Agency (EPA) reports air pollution by State and County.
The US EPA and Google Earth have created a service that allows you to easily find out how air pollution affects your neighborhood. With this Google Earth feature, you are are able to find the sources of air pollution in your neighbourhood, as well as information about the type and quantity of air pollution from each source.
