Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants generated primarily during the incomplete combustion of organic materials (e.g. coal, oil, petrol, and wood). Emissions from anthropogenic activities predominate; nevertheless, some PAHs in the environment originate from natural sources such as open burning, natural losses or seepage of petroleum or coal deposits, and volcanic activities.
Many PAHs have toxic, mutagenic and/or carcinogenic properties. PAHs are highly lipid soluble and, thus, readily absorbed from the gastrointestinal tract of mammals.
