Heavy Metals Contamination in River Water and Sediments of Ganga and Hooghly in India
Abstract
The Ganga River and its tributary Hooghly River in India are distressed by variable levels of heavy metals contamination in river water and sediments by industrial effluents, agricultural runoff, cultural practice, idol immersion and domestic waste. The concentrations of heavy metals (Pb, Hg, Cd & Cr etc) in the river water are repeatedly above the safe limits (above max. admissible & desirable limits) thus making them potentially toxic, hazardous to aquatic lives, ecosystem, biodiversity health and livelihood of people who are using the rivers for drinking, irrigation, pasture and other purposes. The consumption of fish and other aquatic species contaminated with heavy metals poses a risk to food safety and general health of the population including retardation, chronic and acute toxicity, carcinogenic effects, liver and lung damage, neurological & skin diseases, cancer and gastrointestinal disturbances. The result commanding all govt. departments, industries and local communities collaborate to highlight this pollution issues and defend both environmental and human health in India.
