The effluent of a chlor-alkali industry (M/s. Jayashree chemicals Pvt. Ltd., Ganjam) showed significant variation at different points of collection. The effluent was toxic and contained significant amount of mercury as main pollutant. Different parameters studied indicated significant higher values. Each parameter studied singularly can be a pollutant and can severely affect the abiotic component of any aquatic ecosystem. The effluent is not discharged directly in to the river but the leaching of effluent from the storage tank and discharge of effluent periodically into the river, mixing of effluent with the flood water and final drainage into the river contaminating the river, estuary and Bay Bengal warrants attention.
