Distribution and seasonal variation of trace metals in surface sediments of the Mandovi estuary, west coast of India

The concentration and distribution of selected trace metals in surface sediments of the Mandovi estuary were studied to determine the extent of anthropogenic inputs from mining activities and to estimate the effects of the monsoon on geochemical processes in this tropical estuarine system. Analysis of bulk sediments from the Mandovi estuary shows that the concentrations of iron, manganese, cobalt, copper, zinc and lead vary from 2.2 to 49.7%;
