Air pollution is a general term for a variety of substances and gases in our air that pose risks to health.
Most air pollution comes from human-made sources such as fossil fuel combustion, transportation, power plant
emissions and emissions from other industrial processes. Some air pollutants are toxic. Also known as hazardous
air pollutants, these pollutants are known or suspected to cause cancer or other serious health effects, such
as reproductive effects or birth defects, or adverse environmental effects.
