Sediment Contamination Due to Toxic Heavy Metals in Mithi River of Mumbai

Abstract

The present study deals with quantification of accumulated toxic heavy metals in sediments of Mithi River of Mumbai. The study was performed at three different sampling locations along the flow of Mithi River for two years from 2009-12. The different heavy metals studied were Al, As, Cd, Cr, Hg, Ni, Pb, Sr and Mn. The results of our study indicate that the concentration level of these toxic heavy metals for the two assessment years increases by the factor of 1.2-5.8 µg/g. The result is a clear indication of day by day increasing pollution level of the Mithi River, which is creating negative environmental impact on biological life of the river. The results emphasises the need of regular scientific monitoring of different pollutants adversely affecting the environment and to reframe the pollution control strategies already in existence.

Studies on Toxic Heavy Metals in Sediment Ecosystem of Mahim Creek near Mumbai, India

“…The famous Mithi River which is one of the most polluted river of Mumbai [1][2][3][4][5][6] drains into the creek which further drains into the Mahim Bay. It is the only Creek which balances the water level of Mumbai during heavy rainfall and during Mumbai monsoon time.…”

“…This can allow conclusions to be drawn regarding sources of contamination. Since sediments act as a sinks and sources of contaminants in aquatic systems, chemical analysis for characterization of sediments also provides environmentally significant information about natural and anthropogenic influence on the water bodies [9][10][11][12][13][14][15].…”

“…Many of these metals tend to remain in the ecosystem and eventually move from one compartment to the other within the food chain [19,20,[36][37][38][39][40][41][42][43][44][45][46][51][52][53][54][55][56][57][58][59][60]. Food chain contamination by heavy metals has become a burning issue in recent years because of their potential accumulation in biosystems through contaminated water, soil, sediment and air [19,20,[56][57][58][59][60].…”
