Sediment Heavy Metal Contaminants in Vasai Creek Of Mumbai: Pollution Impacts

Abstract

In the present investigation, quantification study of different toxic heavy metals in the sediment samples of Vasai Creek of Mumbai was performed using Atomic Absorption Spectroscopy technique. The study is of importance because such assessment of heavy metals in sediments helps to understand long term pollution load in aquatic environment. Such study will also help to provide a means for evaluating the long term accumulation of heavy metal contaminants. The results of the study indicates that the concentration level of most of the toxic heavy metals like Al, As, Cd, Cr, Hg, Ni, Pb, Sr and Mn for the assessment year 2010-11 were higher than that obtained for the year 2009-10 by the factor of 1.0 to 2.5 µg/g. It is expected that results of present investigation will help in rational planning of pollution control strategies so as to reduce the toxicity impact on marine life of Vasai Creek.

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

“…The mangrove forests are important because of their role in harbouring a variety of biotic communities, protecting the coastal areas from cyclonic storms and functioning as lungs in the case of Mumbai. The increase in number of contaminated sediment sites around the world has resulted in increasing awareness that sediments act as a major pollution reservoir [8][9][10][11][12][13][14][15][16][17][18][19], which has further prompted us to investigate pollution load due to accumulation of toxic heavy metals in sediments of Mahim Creek. It is well known that the sediment strata serve as an important habitat for the benthic macro invertebrates whose metabolic activities contribute to aquatic productivity [20].…”

“…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].…”

Heavy Metals in the Waters of Dąbie Lake (West-Pomeranian Voievodship, North-West Poland)

“…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].…”
