Health Canada has set a maximum acceptable concentration (MAC) of 0.04 μg/L for benzo[a]pyrene (BaP) in drinking water. As the critical effect of the compound is its non-threshold carcinogenicity, the specified level was selected on the basis that exposure to drinking water containing this level of BaP would result in an “essentially negligible” excess cancer risk of 1 in 1,000,000.
