Trophic status of Kolar reservoir based on trace and Heavy metals


Shiv Dyal Meena, Kalpana Dave, Ashwani Wanganeo

Kolar reservoir is used for drinking purpose since 1989 in Bhopal and is the second largest drinking water resource in Bhopal. The present study was conducted to detect the contamination of Kolar reservoir due to trace elements. The various trace elements viz., As, Cu, Fe, Ni, Pb and Zn were analyzed to evaluate the contamination of reservoir by using flame atomization technique of atomic absorption spectrophotometer (AAS-4141). During present investigation the values for various trace elements ranged from 0.001-0.004 for As; 0.022-0.099 for Cu; 0.81-1.87 for Fe; 0.009-0.036 for Ni; 0.001-0.041 for Pb and 0.01-0.05 ppm for Zn. As per WHO (2011) all the elements fall within the safe limits. Though the composition of elements falls within the safe limits yet their presence no longer makes the water body safe. Looking to accumulation rate of the elements the water body has been assigned the mesotropic status.
