[Residues of chlorinated hydrocarbons in livers of newborns, infants and children].

In the liver of 4 newborns, 2 infants and 2 children the levels of residues of chlorinated hydrocarbons were determined. The highest levels of sigma HCH (817 mcg/kg of fat, 17.1 mcg/kg of tissue) were found in a 2-day-old newborn, the lowest ones (43 mcg/kg of fat, 1.8 mcg/kg of tissue) were in an infant aged 12 months. The content of sigma DDT was highest (3044 mcg/kg of fat, 93.8 mcg/kg of tissue) in the liver of an infant aged 13 days, the lowest values (322 mcg/kg of fat, 5.6 mcg/kg of tissue) in the liver of a child aged 12 years. The results are comparable to those obtained in this country in the liver of adults and in human placenta.
