Evaluation of The Trace Metal Contamination in Sediments of the Urban Water Channels in Thrissur City, South India

Present study endeavours to estimate the domain of trace metal contamination in the sediments of water channels of Thrissur city. The major trace elements present in the study area were reviewed and in addition the organic carbon content in the sediments confined to the urban channels was also determined. Thrissur is a newly constituted corporation and is momentarily undergoing nimble urbanization which sequentially place aggravated trace metal pollution. This is habitually caused by land run off, dredging and other linked anthropogenic activities. The discharge of such urban effluents into the natural channels might have contributed to add up accumulation of metals. Correlation with the standard geochemical background values, it is palpable that the average total concentration of lead and zinc are fairly high. Cadmium concentration was found to be inflated in some locations. The contamination factor determined for Ni, Zn, Pb and Cd signify that, these may induce contamination in the sediments. From the correlation studies it is accomplished that, there exists a positive relationship among cadmium, nickel and zinc and that speak to a common source.
