Abstract
Heavy metals are hazardous to soil invertebrates at high concentrations. Earthworm biochemical responses can serve as early signs of soil contamination. The effects of heavy metals such as CuSO4 and ZnSO4 on biochemical parameters such as protein, lipid and glycogen in the earthworm, Eudrilus eugeniae were investigated in present study. After 30 days of exposure, the results revealed that the sub lethal concentrations of both heavy metals significantly reduced the biochemical content of experimental worms compared to the control. Decreased values of protein, triglyceride and glycogen were dose dependent and found to be -24.4% and -10.9%, -26.87 % & -11.44% and -26.09% & -23.91% in worm exposed to 3/4th sub lethal concentration of CuSO4 and ZnSO4 respectively.
