Abstract

Effluents are main source of direct and often continuous input of pollutants in to aquatic ecosystem with long term implications on ecosystem functioning. In present study, an investigation has been made to ascertain the effect of tannery effluents (untreated and treated) on quality Ganga river water near Jajmau area at Kanpur city, India. The effluents were mixed with Ganga river water at concentration of 5%, 15%, 25%, 50% and 75% v/v and analyzed for physicochemical parameters like pH, conductivity, total dissolved solids (TDS), total alkalinity (TA), total hardness (TH), dissolved oxygen (DO), biological oxygen demand (BOD) and chemical oxygen demand (COD) in laboratory condition. The results of the study indicate that incorporation of tanneries effluents make highly adverse effect on river Ganga. So the result obtained shows that tannery wastewater is added continuously in river water, few years from now, serious water quality deterioration could take place, which will serious threat to aquatic and human life.
