Polycyclicaromatichydrocarbons (PAHs) arecommonenvironmental pollutants, affectingair,water, and soil quality.
Althoughnaturallyoccurring, human impacthas createda steady increase inenvironmental levelsof PAHsand their
byproducts. PAHsare typically formed through the incompletecombustionof organicmaterials, suchaswood, coal,
andoil, but arealsoused inmanufacturingof somemedicines, plastics, andpesticides.ManyPAHsareknownor
suspectedcarcinogens. TheUnitedStatesEnvironmental ProtectionAgencycurrently listsandmandates testingof
the16PAHs theydeemmosthazardous.
