Abstract

Abstract

The flora and fauna of soil ecosystem are negatively impacted by the repeated use of chemical pesticides in agricultural fields. Over time, there has been significant concern over the use of glyphosate-based herbicides worldwide and the release of glyphosate residues into the soil environment. This intentional discharge of pesticides into the soil environment highlights the urgent need to track the herbicides' ecotoxicological risk assessment and lessen any potential negative effects. From this view point, the present study investigates the toxic effects of herbicide glyphosate on the earthworm, Eudrilus eugeniae. The non-enzymatic antioxidant, glutathione and the hepatic antioxidant enzymes, SOD, CAT, GST and GPx in the epigeic earthworm.  The outcomes showed that the activities of these biomarkers were strongly impacted by the sublethal exposure of glyphosate. Exposure also changed levels of LPO products, including conjugate diene and malondialdehyde.
