Abstract

Study was conducted to evaluate the effect of mercuy chloride on lipid content and catalase activity in various tissues of fresh water gastropod snail’s, Bellamya bengalensis. The effect on snail’s was studied under two groups. Group A was maintained as control, group B of snail’s was exposed to chronic LC 50/10 dose of HgCl2 (0.109ppm) for 21 days. Lipid content and catalase activity in selected tissues hepatopancreas and gonads of Bellamya bengalensis.from both groups were estimated after 7, 14 and 21 days. Significant decrease in glycogen content and catalase activity were observed in HgCl2 exposed snail’s as compared to control.

Keywords: Mercury, Lipid content, Catalase activity and Bellamya bengalensis.
