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

Abstract

  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 4^th day and nonsignificant differences between 4^th and 8^th 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.
