Endosulfan is an organochlorine acaricide used to kill pests of cotton, jute, vegetables and sugarcane. It is a chlorinated hydrocarbon of cyclodiene subgroup which is among the most toxic pesticides for aquatic life, especially fish, and therefore has been registered as a priority pollutant by the US Environmental Protection Agency. It is more toxic to the fish model of the present study, as the fish is a mud dweller and remains in contact to the soil for longer time. Endosulfan is moderately persistent in the soil environment with a reported average field half-life of 50 days. Blood parameters are valuable indicators for monitoring pollution load, stress and diseases caused by toxicants and are known to fluctuate with eco-physiological factors, which often are subjected to rapid changes due to various types of pollution. In the present study, toxic impact of Endosulfan on various blood parameters of Clarias batrachus Linn. was estimated. The levels of acid phosphatase, alkaline phosphatase and C-reactive protein were found to be raised, while the plasma cortisol level was found to be lowered in response to toxicant exposure.

Abstract


Endosulfan is an organochlorine acaricide used to kill pests of cotton, jute, vegetables and sugarcane. It is a chlorinated hydrocarbon of cyclodiene subgroup which is among the most toxic pesticides for aquatic life, especially fish, and therefore has been registered as a priority pollutant by the US Environmental Protection Agency. It is more toxic to the fish model of the present study, as the fish is a mud dweller and remains in contact to the soil for longer time. Endosulfan is moderately persistent in the soil environment with a reported average field half-life of 50 days. Blood parameters are valuable indicators for monitoring pollution load, stress and diseases caused by toxicants and are known to fluctuate with eco-physiological factors, which often are subjected to rapid changes due to various types of pollution. In the present study, toxic impact of Endosulfan on various blood parameters of Clarias batrachus Linn. was estimated. The levels of acid phosphatase, alkaline phosphatase and C-reactive protein were found to be raised, while the plasma cortisol level was found to be lowered in response to toxicant exposure.
