Human Exposure to PAH from Sources other than Drinking Water
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds which are known to be carcinogenic. This report examines the contributions to total human exposure to PAHs from sources other than drinking water, and compares them with the exposure from drinking water. The report concludes that exposure to PAHs is very variable, according to lifestyle, diet, time of year and location. This makes it difficult to determine the relative contribution which any particular source may make to total exposure. However, food provides by far the largest source of exposure. For most drinking water suppliesm the relative contribution is negligible, (about 1%). For supplies which have elevated PAH levels due to contact with coal- tar pitch linings, drinking water could account for up to two thirds of the daily intake of one PAH, fluoranthene, where contributions from other sources are minimal. Since a high concentration is likely to be transitory in drinking water, the relative contribution is likely to be much lower.
