Air pollution
Air pollution is the introduction of chemicals, particulate matter, and biological materials into the atmosphere, which causes harm or discomfort to humans and other living organisms. These problems are traditionally identified with major stationary sources (power plants, smokestacks), but the greatest sources of emissions are mobile, mainly automobiles.
