Abstract

The present study deals with the geochemical fractions of nine heavy metals [chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb)] present on the river sediments using sequential extraction process (SEP) and total acid digestion (TAD). This work was conducted on Ganga river sediments at Varanasi. Various sources of the metal pollution in the city include domestic, industrial and agricultural untreated wastewater draining into the river. Geochemical fractions of the metals–pH relation study, using Medusa Hydra chemical equilibrium software, revealed the presence of different species of metals at different pHs
