印度Sukinda铬铁矿区水样的重金属污染、理化性质和微生物的评价

             

摘要

Water samples from chromite mine quarry of Sukinda and its adjacent areas were analyzed for their heavy metal contamination along with physico-chemical and microbial contents.The chromite mine water samples possessed high concentrations of heavy metals in the order of Cr>Fe>Zn>Ni>Co>Mn while ground water did not show any heavy metal contamination except Fe.Physico-chemical parameters of mine water samples showed deviation from those of normal water.Mine water harboured low microbial populations of bacteria, fungi and actinomycetes in comparison with mine adjacent water samples.The correlation of data between metals with physico-chemical parameters showed both positive and negative responses while that of metal and microbial population exhibited negative correlation.Bacterial strains isolated from chromite mine water exhibited high tolerance towards chromium and other heavy metals as well as antibiotics which could be used as an indicator of heavy metal pollution.%分析了Sukinda铬铁矿采石场及其邻近区域水样的重金属污染及理化性质和微生物含量.铬铁矿的水样含有高浓度重金属,其浓度顺序为Cr>Fe>Zn>Ni>Co>Mn,然而该地区的地下水除了Fe以外并没有受到重金属污染.矿井水样的理化参数与正常水的有差别.与相邻矿水样相比,矿井水样含有一些低浓度的微生物种群,包括细菌、真菌和放线菌.金属浓度与相关的理化参数显示了他们之间有正、负响应,而金属浓度和微生物种群之间表现出了负的相关性.从铬铁矿废水中纯化出来的菌株对铬和其他的重金属以及抗生素表现出高的耐受性,可作为重金属污染的指示剂.
