The atmosphere–land–water connectivity of nutrients is not altogether accounted for in the Ganges Basin despite recent studies highlighting its importance. Together with surface inputs, rivers receive N and P through atmospheric deposition (AD), directly on water surfaces, and through lateral transport.

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.
