How does air pollution spread from one place to another?
Air pollutants can be transported by wind, causing a pollution to spread widely. Rain can remove pollutants from air, causing soil and water pollution. Sunlight can aid the convertion of air pollutants to different substances. Air pollution is caused by both human and natural sources.
Does air pollution circulate globally?
Although most air pollution problems are caused by local or regional sources of emissions, air pollution does not stop at national borders. Some air pollutants are known to circulate globally and deposit on land and water bodies far from their sources.
How far can particulate matter travel?
PM10 particles can travel as little as a hundred yards or as much as 30 miles. PM2. 5 particles go even farther; many hundreds of miles.
Where does most of the air pollution come from?
Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.
