BIOSIS COPYRIGHT: BIOL ABS. In adult albino rats, maternal dietary beta- and gamma-hexachlorocyclohexane (HCH) intake during gestation upto 400 ppm level did not affect the number of litters produced. But about 50 and 100% pup mortality was found in 200 and 400 ppm/beta-HCH group within 5 days of birth. Maternal mortality was observed in 800 ppm beta-HCH group during third week of gestation. The effect of maternal dietary intake of HCH isomers at 50 and 250 ppm level during gestation and/or lactation on perinatal developme also studied. The body weights and sizes of the newborn litters of mother rats exposed to dietary HCH isomers did not differ from controls. Similarly, the growth and development of the litters of HCH exposed mother rats that survived 28 day lactation period were found to be comparable to controls as evidenced by the body weight and weight of vital organs. However, liver weight increases were found in the 28 day weaned litters wherever the mothers had been exposed to HCH isomers d
