ABSTRACT:

Heavy metal pollution has become a serious health concern in recent years, because of industrial and agricultural development. Heavy metals of industrial bio-waste contaminate drinking water, food and air. The toxic heavy metals of great concern are Cd, Pb and Hg which are usually associated with harmful effects in men and animals. It is recognized that heavy metals may exercise a definite influence on the control of biological functions, affecting hormone system and growth of different body tissues. Many heavy metals accumulate in one or more of the body organs with differing half-lives. The Heavy Metal Pollution Index (HPI) of ground water was found to be far below the index limit of 100 points indicating that the ground water was not polluted with heavy metals in spite of the prolific growth of mining and allied industrial activities near the town. India revealed that Cd concentration varied from 1.0 to 9.1 ppm, Cu varied from 8.0 to 10.2 ppm and Pb content ranged from 0.1 to 10.4 ppm. In many district of Uttar Pradesh, India, most of the water bodies are being used for the cultivation of edible aquatic plants. It was found to be contaminated with a variety of toxic metals like Fe, Cu, Cr, Mn and Pb. Soils irrigated with the effluents had higher contents of micronutrients and heavy metals as compared to the corresponding well irrigated soils. water, soil, grass and mineral salt samples to investigate the sources of toxicity in animals. In this paper discussed the metal Pb, Cd, Zn, Ni, Cu, Fe and Mn are in different concentration in all the study Jhansi sites.
