PDF-Polycyclic Aromatic Hydrocarbons (PAHs)Polycyclic aromatic hydrocarbon

Finding a measurable amount of one or more PAH metabolites in the urine does not mean that the levels of one or more PAH metabolites or PAHs cause an adverse health effectBiomonitoring studies on leve. PAHs are found naturally in the environment but they can also be manmade In their purest form PAHs are solid and range in appearance from colorless to white or pale yellow green PAHs are created when products like coal oil gas and garbage are burned By Kathleen Barbosa.
