摘要：Halali reservoir is a freshwater resource of Madhya Pradesh. It receives untreated domestic sewage andmunicipal wastes and also agricultural runoff from the surrounding areas. Different heavy metals (Fe, Mn, Niand Pb) were measured in Halali reservoir during 2007-08 by using ICP-OES. Heavy metal contents werefound significantly different among the sites and varied in the seasons. All the metals were higher at stationH1 and confirm this site as a major source of pollution in the reservoir. Heavy metal content in planktonfollowed the order: Fe>Mn>Pb>Ni in all the seasons. Pb showed the highest bioaccumulation with high BAFvalues, although it was within the permitted level in reservoir’s water. In this communication the concentrationof metals in plankton can affect the associated fauna of the water body, and finally the impact can be seen onhuman health by the process of biomagnification.
