Lipid peroxidation and alkaline phosphotase levels in gastropod Lymnaea Radix cor (Annandale and Prashad, 1919 ) exposed to sublethal concentrations of endosulfan

The gastropod Lymnaea Radix cor was exposed to sub lethal concentrations ( 22.75 and 45.5 μg/L ) of endosulfan for 8 days. Important biomarkers were assayed in digestive glands during exposure intervals ( 2, 4 and 8 days ). Increasing in lipid peroxidation, markers including Malondialdehyde (MDA), was observed after 2 days of exposure with 22.75 μg/L endosulfan then the increasing became lower in 4th day and nonsignificant differences between 4th and 8th days of exposure were noticed. while the increase in lipid peroxidation was greater after 2 days of exposure with 45.5 μg/L endosulfan than that at 22.75 μg/L. The results showed decrease in Alkaline phosphatase enzyme in second day of exposure with 22.75 μg/L endosulfan whereas more decreasing in ALP were observed after 2 day of exposure with 45.5 μg/L endosulfan.
