Abstract: Present study highlighted significant anthropogenic contributions in terms of heavy metal pollution in Mandovi estuarine complex. Sediment core was collected which was analyzed for different physico-chemical parameters. Sediments were found to be mature, quartz rich and weathering does not seem to play any role. Biological activities were significant due to abundance of S and OC in the sediments which along with the redox conditions controlled the metal variability. Sediments were found to be enriched with respect to heavy metals like Pb and Mn indicating anthropogenic influence in this region.
