[Contamination of adipose tissue of slaughter animals with chlorinated insecticides and hexachlorobenzene in the Central Bohemian Region].

Residues of some chlorinated pesticides (hexachlorobenzene, lindane, DDE, DDT) were detected in adipose tissues of commercially important animals in Central Bohemia; the method of gas chromatography and an electronic detector were used. Residues of chlorinated hydrocarbons were detected in all examined samples, the hexachlorobenzene concentration was explicitly higher than the concentrations of DDT and lindane. The hexachlorobenzene residues occurred locally. The hexachlorobenzene concentrating detected in the adipose tissues of cattle and pigs were higher than in some European countries; the DDT and lindane concentrations were at the same level.
