Chlorinated pesticide residues in testicular tissue samples. Pesticides in human testicles.

Residues of chlorinated pesticides--HCB, alpha-, beta-, gamma-, delta-, epsilon-HCH isomers, heptachlor epoxide, DDE and DDT isomers in bilateral testicular biopsy material were determined in gas liquid chromatography with electron capture detector (GLC-ECD). The average levels of chlorinated pesticides residues occurring in 36 men are presented. Alpha-, delta-HCH and p,p'-DDE were observed in nearly all analyzed samples. Other analyzed compounds were observed in lower percentages, whereas o,p'-DDT and p,p'-DDT were not detected.
