Heavy metal contamination of Ganga river at Varanasi in relation to atmospheric deposition
We investigated the mid stream water quality of Ganga river as influenced by aerially - driven heavy metals at Varanasi, India. Twelve sampling stations were selected along a 20 km long stretch of the river. Mid stream sub-surface water samples collected at fortnightly intervals from all the sites were acid digested and analyzed for Cd, Cr, Cu, Ni, Pb and Zn.
