Abstract

The present study has investigated the toxic effect of Atrazine on the intestine of the earthworm L. mauritii in a laboratory experiment. A sub-lethal concentration of Atrazine (1/5th of 96 h LC50 value-1.99 mg/kg) was applied for 30 days. The changes such as vacuolization, degenerated nuclei, damaged epithelial lining of villi and congestion of blood sinuses were observed in the intestine of 1st, 5th and 15th day of Atrazine exposure. In the 30th day of exposure, slight damages were observed. These results suggest that Atrazine could severely affect the intestine of 1st, 5th and 15th day of exposure when compared to 30th day. Histopathological study in L. mauritii’s intestine is a suitable parameter for detection of soil contamination by application of pesticides in agricultural field.
