Heavy metal contamination cause of idol immersion activities in urban lake bhopal, India

Water resource of the earth is part of a finite close system, and in any time period when population are rising, the per capita amount of water available is inevitably decreasing. Water quality of lake are normally get contamination every where by accumulation of sediments, human waste, sits organic matter, industrial waste but in India different type of religious activities (Idol immersion) are take place every year to which other country are not concern.

The idol are been made up of Clay, Plaster of paris, cloth, paper, wood, thermocol, jute, adhesive material and synthetic paints etc. Out of the all martial used in making the idol, thermocol is Non-Biodegradable while paints contain heavy metals such as Chromium, Lead, Cadmium and Mercury. The present study was under taken to evaluate heavy metals. The findings of the study Increase Heavy Metals contamination after idol immersion, nickal,lead and mercury may magnify in their concentrations at different tropic levels, including in fishes and birds inhabiting the lake, which finally reach the humans through food.
