Embryotoxic and teratogenic effects of interaction of cadmium and lindane in rats.

Embryotoxic and teratogenic effects of cadmium and lindane were studied in rats. Cadmium or lindane alone did not produce any significant malformations in the 20 day old foetuses whereas their combination caused significant reduction in the body weight of dams and pups and increased total embryonic deaths. Skeletal deformities like wavy ribs, reduced skull ossification and reduced caudal vertebrae were potentiated in coexposure group. The study indicated that the simultaneous exposure to cadmium and lindane may have more deleterious effects on the developing foetus compared to either alone.
