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.

Abstract


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.
