Distribution o fPAH hepatic levels infish from the study area Exposure and effects: New maximum levels of PAHs in foods have been introduced by the European Commission. PAHs are recognised as genotoxic carcinogens, and as such levels in food should be as low as reasonably achievable. Food manufacturers will need to carry out analysis to show compliance with the new limits, and to ensure that manufacturing processes do not result in PAH formation in their products. According to the Scientific Committee on Food, benzo(a)pyrene can be used as a marker for the occurrence and effect of carcinogenic PAH in food, including also benz(a)anthracene, benzo(b)fluoranthene, benzo(j)fluoranthene, benzo(k)fluoranthene, benzo(g,h,i)-perylene, chrysene, cyclopenta(c,d)pyrene, dibenz(a,h)anthracene, dibenzo(a,e)pyrene, dibenzo(a,h)pyrene, dibenzo(a,i)pyrene, dibenzo(a,l)pyrene, indeno(1,2,3- cd)pyrene and 5-methylchrysene. From April 2006 new maximum levels for benzo(a)pyrene in fish and meat products will be 5 ng/kg, in oils and fats 2.0 |ig/kg and in children's foods 1 |ig/kg. Maximum permissible level of benzo(a)pyrene is established also for smoked fish - 0.005 mg/kg (Commission Regulation (EC) No 208/2005). In Russia several PAH compounds are considered as carcinogenic (List of chemical compounds, products, industrial processes, natural and domestic factors which are carcinogenic for humans, 1998), they are: Benzo(a)pyrene, Benzo(a)anthracene, and Dibenzo(a,h)anthracene. Maximum permissible level of benzo(a)pyrene in Russia is established only for smoked fish - 0.001 mg/kg (Sanitary-hygienic requirements, 2001). Akvaplan-niva report APN 514-3365.02 21
