The present study reveals that urban centres act as sources of Cr, Ni, Cu, Zn, Pb and Cd and cause metallic sediment pollution in rivers of the Ganga Plain.Īckermann, F.: 1980, ‘A Procedure for Correcting the Grain Size Effect in Heavy Metal Analysis of Esturine and Coastal Sediments’, Environ. ![]() Heavy metal analysis in the <20-μm-fraction of stream sediments appears to be an adequate method for the environmental assessment of urbanisation activities on alluvial rivers. Stream sediments from Lucknow, Kanpur, Delhi and Agra urban centres have been classified by the proposed Sediment Pollution Index as highly polluted to dangerous sediments. ![]() Metal enrichment factors for the stream sediments were Cu > Cr > Ni and Cu > Zn > Cr > Ni, respectively. Freshly deposited stream sediments from six urban centres of the Ganga Plain were collected and analysed for heavy metals to obtain a general scenery of sediment quality.
