摘要:
Dietary feeding of technical hexachlorocyclohexane (HCH) at 125 and 250 ppm to rats have not shown any adverse effects on reproductive function and were comparable to control animals in a three-generation study. There were no major malformations, while some minor variants found were not compound or dose related. Despite some mild toxicological effects in rats of the P-0 generation, the litters of F-1B, F-2B and F-3B generations were devoid of any morphological or teratological changes. The presence of HCH residues in vital tissues of F-3B pups have indicated transmigration of HCH in preceding generations but not to an extent that produced adverse effects.
