Chlorpyrifos pesticide toxicity on erythrocyte sedimentation rate in<br /> fish, Channa punctatus (Bloch.)
Journal Title: Biology and Medicine - Year 2009, Vol 1, Issue 2
Abstract
Almost all the pesticides and more particularly the synthetic pesticides used, find there way into water bodies alter the metabolism of aquatic organisms is known long back. In the present investigation, the effect of sub lethal concentration of chlorpyrifos toxicity on fish Channa punctatus were studied after 24hrs, 48hrs, 72hrs and 96hrs exposure respectively. Chlorpyrifos is an organophosphate insecticide that kills insects by disrupting there nervous system and is effective against a wide range of plant eating insects. Suspected effects of chlorpyrifos exposure include birth defects, increased rate of leukemia and immune system abnormalities. The results indicated a significant increase in ESR (mm/hr) 2.57mm/hr, 2.60mm/hr, 2.71mm/hr and 2.83mm/hr when compared to control group 2.56mm/hr fallowing both acute and sub acute exposure of chlorpyrifos.
