Elevated level of heavy metals act as toxicants to flora and fauna of an ecosystem. Earthworms have the ability to bioaccumulate these heavy metals in yellow cells of their body thus help in bioremediation process to eliminate heavy metals from the soil. Depending upon the doses and exposure period to these heavy metals, earthworm’s body find affected. That’s why the investigation was conducted to check the effect of Hg and Cd on earthworm Eudrilus eugeniae. Six doses viz. Hg 0.17, 0.22 and 0.29% and Cd 0.27, 0.37 & 0.51% was sprayed for a period of 60 days. After 1st, 30th and 60th day of exposure, body tissue carbohydrate and protein were analyzed. It was concluded that Hg 0.29% affect the biomolecular concentration of body of earthworm Eudrilus eugeniae followed by Cd. Maximum reduction in carbohydrate i.e. 25.32% and that of protein was 32.98% at the dose of Hg 0.29%.
