Details of Air Pollution
|
Pollution or contamination of the atmosphere with substances which are not generally found there (or are found in very small amounts). Pollutants can be gaseous, liquid (in the form of droplets), or solid (in the form of dust). The major source of air pollution today is industry, although cars and other forms of transportation using fossil fuels are also very important. Under certain circumstances, agricultural practices can be an important source of pollution by dust. Air pollutants can be toxic or otherwise harmful to humans and other living species. They can also harm buildings and other man-made objects. They can alter air quality, especially they can reduce visibility. Finally, they can modify important environmental cycles - dusts can increase reflection of sunlight, thus tending to cool the atmosphere, other chemicals can increase the thermal opacity of the atmosphere, thus tending to heat up the atmosphere (see greenhouse effect). Air pollution impacts at the local level, but they can also impact at the regional level (e.g., photochemical smog, acid rain) or at the planetary level (e.g., CFCis, CO2).
