In the present investigation, the study was carried out on pollution, fish mortality and water born human diseases have revealed severe pollution in the fresh water ecosystem. The fish Cyprinus carpio collected from Tapi river at Bhusawal region was exposed to heavy metal i.e. Cadmium chloride. The 24h acute toxicity test yielded a LC50 of the 0.2% from which 1/3rd and 1/6th submittal concentrations 0.1 and 0.05% respectively. The experimental work was carried out for 120h after 120h of exposure the measure proximate constituents i.e. protein, carbohydrate and lipid level were quantified. The accumulation of cadmium in the soft tissue of Cyprinus carpio was also analysed. The control group of animals showed minute quantity of cadmium as compared to the experimental group.
