Oznaczono pozostałości chlorowanych węglowodorów: y-HCH, DDT i jego metabolitów DDE i DDD, w mleku kobiecym pozyskanym w roku 1996 w Olsztynie. Uzyskane wyniki badań porównano z wcześniejszymi badaniami przeprowadzonymi w latach 1986 i 1976 w tym samym regionie.

Residual amounts of organochlorine insecticides: y-HCH, DDT and its metabolites DDE and DDD were determined by gas chromatography in human milk collected in Olsztyn in 1996. The results were compared with the results obtained earlier in 1976 and 1986 in the same region of Poland. It was observed that with time the amount of chlorinated hydrocarbons tended to decline. The residual amount of SDDT in 1996 was 8 times lower than in 1986 and 19 times lower than in 1976. On the other hand, the amount of y-HCH in 1996 was 7 times lower than in 1986 and 41 times lower than in 1976. Although the quantity of ZDDT decreases with time, it still exceeds considerably the Maximum Residue Levels of these compounds in baby food.
