    Journal: J Environ Sci Health B; 2010 Oct; 45(7):658-65. PubMed ID: 20818519.
    Abstract:
    The aim of this study was to determine the concentration of organochlorine pesticides [HCH and isomers (alpha, beta, gamma), aldrin, dieldrin, endrin, heptachlor and heptachlor epoxide and DDT and its metabolites (op'-DDD, pp'-DDD, op'-DDT, pp'-DDE, pp'-DDT] in smoked fish. Analysis was made of 12 typical smoked fish products that are the most popular among customers from the city of Szczecin, Poland. Pesticide residues were found in all samples of smoked fish. The smoked sprat and cold-smoked Baltic salmon were the most contaminated smoked fish products in terms of chlorine pesticides. The sum of DDT metabolites ranged from 1.48 (smoked mackerel) to 35.53 ng/g wet weight (smoked sprat), with the lowest concentrations found for op'-DDT and the highest for pp'-DDE. The level of heptachlor epoxide isomer B was low and ranged from 0.06 +/- 0.01 (smoked eel) to 0.27 +/- 0.07 ng/g w.w. (smoked sprat). The content of heptachlor was 0.48-1.99 ng/g w.w. Concentration of endrin was higher compared to other pesticides, ranged from 1.50 (cold-smoked salmon fillet) to 16.84 ng/g w.w (hot-smoked warehou). The contamination of smoked products was significantly low and poses no risk to the health of consumers provided that they eat a diverse diet. The concentration of organochlorine pesticides in the analysed products was below the standards accepted in European countries.
