Paper Title
Assessment Of Heavy Metal Contents In Surface Water-Bodies (Lakes)

Abstract
The pollution of the aquatic environment with heavy metals has become a worldwide problem during recent years, because they are indestructible and most of them have toxic effects on organisms. Food chain contamination by heavy metals has become a burning issue in recent years because of their potential accumulation in bio-system through contaminated water, soil, sediment and air. Hence in the present investigation, efforts are made to quantify the accumulation of toxic heavy metals in various lakes (Ambazari, Futala and Gandhisagar lake) in Nagpur city, Maharashtra, India. Water samples were collected at morning hours during pre immersion, immersion and post immersion periods. The immersion of idol of Lord Ganesh, Lord Viswakarma and Goddess Durga during month of August to October is a major source of contamination and sedimentation to the studied lakes in Nagpur city. The idols are been made up of clay, plaster of paris, cloth, paper wood, thermocol, jute, adhesive materials and synthetic paints. Out of all materials use in making idols, thermocol is non-biodegradable while paints contain heavy metals such as chromium, lead, cadmium and mercury. The findings of the increase heavy metal concentration after immersion may magnify in their concentrations at different tropic levels by food chain. On the basis of changes it is concluded that the level of water pollution increases in lakes due to religious activities and cause adverse effect to the aquatic life or entire aquatic ecosystem. The average level of metals in all studies lakes followed order Zn>Fe> Pb>Mn> Cu>Cd.It is observed that values of heavy metals significantally increased during immersion period and then declined in post immersion period , however, the general trend observed was : immersion > post-immersion > pre-immersion period. No one can change or stop these religious activities but awareness among the people and society can reduce the pollution. Keywords: Physicochemical analysis, WQI, lake, water pollution, festivals, surface water
