Air Toxics from Motor Vehicles :- What are Air Toxics?
What are Air Toxics?
Air toxics are air pollutants that cause adverse health effects. The U.S.
Environmental Protection Agency (EPA) has focused most of its air toxics
efforts to date on carcinogens, which are compounds that cause cancer.
Non-cancer health effects such as reproductive and neurological problems are
also of concern to EPA.
How dangerous are air toxics? It’s hard to say. Some air toxics have been
proven to cause cancer in humans. However, most air toxics are identified
through laboratory experiments in which animals receive very high doses of
the compound being studied. People almost never breathe such high doses.
But lower exposures may still pose risks. One fact is clear: vehicles are such
an integral part of our society that virtually everyone is exposed to their
emissions.
