Abstract

There was performed the assessment of polycyclic aromatic hydrocarbons (PAH) content in food. These contaminants were established to present in all analyzed groups offood products. Benzo(a)pyrene was found in meat, dairy products and milk. The determined pollution levels (from traces concentrations (<0,05 mkg/kg to 0,41mkg/kg) do not exceed the maximum permissible concentrations accepted in the country (5 mkg/kg). In fish and eggs PAH were found substantially in trace concentrations. The highest PAH levels were found in meat products (45,65 mkg/kg). In these products for phenantrene there was recorded the highest concentration - 21,97 mkg/kg. There was made a calculation of daily intake of contaminants for the average statistical consumption offood per capita, as well as according to minimal standards of food included in the food basket of the subsistence minimum. Benzo (a) pyrene intake for men was established to be 0,044 mkg/kg/ day, PAH groups of probably carcinogenic to humans - 0,14 mkg/kg /day, and the total amount of PAHs - 1,51 mkg/kg/day. The intake of studied contaminants in women (5 mkg/kg) was noted to be less than in men.
