[Chlorinated hydrocarbon residues in the livers of the population of Białystok and its environs].

In the livers of 34 subjects living in Białystok and environs the residues of chlorinated hydrocarbons were determined. The mean values of alpha-HCH, beta-HCH, gamma-HCH, DDE, DDD, DDT and sigma DDT were respectively 16, 60, 81, 1090, 94, 177 and 1361 mcg/kg of fat, and 0.5, 3.2, 3.3, 48, 5.0, 7.1 and 60 mcg/kg of tissue. The content of DDE and sigma DDT in liver fat was similar to that found previously in perirenal fat. In relation to perirenal fat the content of DDT in liver fat was lower and that of DDD was higher. This was due, probably, to metabolic changes taking place in the liver. The relationship between beta-HCH and gamma-HCH in the liver was different from that in fatty tissue in which the level of Indian was lower than that of the beta-isomer.
