Chronic effect of chlorpyrifos on histoarchitectural alterations in gill, liver, kidney

Abstract

Chlorpyrifos is a wide ranging organophosphorus insecticide used to control agricultural and household pests. In the present study the chronic effect of chlorpyrifos at sublethal concentration (0.661 µg/L) was assessed in fish, Etroplus maculatus in order to evaluate the histoarchitectural alteration in various tissues as gill, liver, kidney and spleen. Fish ranging3.5 ± 0.5 g in weight and 6 ± 0.3 cm length was used in the study and are exposed to chlorpyrifos for 15 days maintaining the control group.
