What are PAHs?

Polycyclic aromatic hydrocarbons – or PAHs – are aromatic (airborne) toxic chemicals that are formed whenever anything with a carbon base (such as wood, gasoline, or meat) is burned. They are known to be carcinogenic, mutagenic, and/or teratogenic (causing birth defects), and they are major contaminants of not only paved areas, but adjacent homes and local rivers.
