Abstract

Beryllium is widely used in fatigue-resistant alloys, nuclear reactors, space device, missiles parts, electronics and other specialized purposes. Workers both in industries and mines are constantly exposed through inhalation or direct skin contact. A number of investigations have been made in different laboratories in relation to its toxicological effects in laboratory animals and humans. The lethal dose (LD/sub 50/) of beryllium nitrate through intravenous route in rats has been reported from our laboratory to be 3.16 mg/kg body weight. But not much is known about its effects on reproductive physiology. The present communication deals with the effect of beryllium nitrate on early and late pregnancy in the albino rats.
