本研究从2012年6月至2013年5月进行了为期一年的时间，以了解孟买附近的Mahim溪沉积物中有毒重金属的水平。重金属Pb、Cd、Cr、Zn、Cu、Ni和Hg的年平均浓度分别为9.88、2.33、1.41、33.31、22.07、32.21和32.06ppm。这些重金属在溪流沉积物中的累积可能会影响底栖大型无脊椎动物的代谢活动，从而影响水产生产力。本研究结果表明，现有的情况下，如果处理不当，会导致有毒的影响，沉积物栖息生物和鱼类，导致生存减少，降低生长，或受损的繁殖和物种多样性降低。
The present study was performed for the period of one year from June 2012 to May 2013 in order to understand the level of toxic heavy metals in the sediments of Mahim Creek near Mumbai. The annual average concentration of heavy metals like Pb, Cd, Cr, Zn, Cu, Ni and Hg was found to be 9.88, 2.33, 1.41, 33.31, 22.07, 32.21 and 32.06 ppm respectively. It is feared that this heavy metals accumulated in the creek sediments might affect the benthic macro invertebrates whose metabolic activities contribute to aquatic productivity. The results of present study indicates that the existing situation if mishandled can cause toxic effect on sediment dwelling organisms and fish, resulting in decrease survival, reduced growth, or impaired reproduction and lowered species diversity.
