In last few decades, due to the rapid increase in the population, industrialization and newer agricultural practices, the aquatic resources of India have been deteriorating. The pollution of aquatic ecosystems by heavy metals is of a great concern due to their persistence, toxicity and accumulative behaviour. The heavy metals can change the trophic status of aquatic ecosystems and make them unsuitable for various purposes. They also pose a serious threat to human health. This paper reviews the heavy metal contamination of sediments of Indian inland water bodies. It also discusses the possible sources of pollution. Different standards for sediment pollution which are in use have also been discussed. It showed that environmental degradation has become a major societal issue in India due to uncontrolled anthropogenic activities, besides natural factors. There is an urgent need of creating awareness amongst the public of these problems and find preventive and remedial solutions for management. Expensive high-tech remedial measures are not suitable for the country, and hence emphasis has to be given on prevention. Indigenous research towards mitigation and remediation has to be encouraged, keeping in mind India's unique problems of poverty, crowding and malnutrition.Keywords

Halali reservoir is a freshwater resource of Madhya Pradesh. It receives untreated domestic sewage and municipal wastes and also agricultural runoff from the surrounding areas. Different heavy metals (Fe, Mn, Ni and Pb) were measured in Halali reservoir during 2007-08 by using ICP-OES. Heavy metal contents were found significantly different among the sites and varied in the seasons. All the metals were higher at station H1 and confirm this site as a major source of pollution in the reservoir. Heavy metal content in plankton followed the order: Fe>Mn>Pb>Ni in all the seasons. Pb showed the highest bioaccumulation with high BAF values, although it was within the permitted level in reservoir's water. In this communication the concentration of metals in plankton can affect the associated fauna of the water body, and finally the impact can be seen on human health by the process of biomagnification.Keywords
