摘要

地下水污染监测已成为确定实现可持续发展目标3(良好健康和福祉)和目标6(清洁水和卫生设施)的关键。本研究分析了singruli矿区地下水中14种重金属浓度的季节变化及其对人体健康的潜在危害。重金属的平均浓度在随后的季风期订单:铁英航B >锌> > >锰> Al > Cr >铜>铅>镍> >有限公司> > Cd Ag),在post-monsoon,它是:锌>铁>锰>英航> Al B >铅> >镍> Cr >铜>镉> > Ag) >有限公司。除Zn、Cd和Pb外,季风季节各金属浓度均高于季风后季节。单因素方差分析结果表明,研究区B、Al、Cr、Fe、Co、Ni、Cu、As、Ag和Ba的浓度存在显著的季节变化。因子分析表明,地下水中重金属的存在既有地质因素的影响,也有人为因素的影响。季风期(29)和季风后(10)的重金属污染指数平均值均小于临界值(bbb100),表明污染程度较低。Nemerow指数(NI)平均值(2.58,0.63)表明季风期污染中度,后季风期污染程度较低。该研究揭示了所有年龄组的致癌健康风险(由于Cr、Cd和Pb)和非致癌风险,特别是儿童,其次是成年人和婴儿。

Heavy metal pollution assessment of groundwater and associated health risks around the coal mining area, Singrauli, Madhya Pradesh, India.

Groundwater pollution monitoring has become crucial for ascertaining the fulfilment of Sustainable Development Goals 3 (good health and well-being) and 6 (clean water and sanitation). This study analyses the seasonal variation in the concentration of 14 heavy metals along with potential human health risks associated with groundwater in the coal mine area of Singrauli. The mean concentration of heavy metals in the Monsoon phase followed the order: Fe > Ba > Zn > B > Mn > Al > Cr > Cu > Pb > Ni > As > Cd > Co > Ag, and during the post-monsoon, it was: Zn > Fe > Mn > Ba > Al > Pb > B > Ni > Cr > Cu > Cd > As > Ag > Co. The metal concentrations (except Zn, Cd and Pb) were found to be higher during the monsoon season than during the post-monsoon season. The results of the one-Way ANOVA indicated a significant seasonal variation in the concentrations of the B, Al, Cr, Fe, Co, Ni, Cu, As, Ag and Ba in the study area. Factor analysis revealed that both geogenic and anthropogenic sources contributed to the presence of heavy metals in groundwater. The mean value of the Heavy Metal Pollution Index for the monsoon (29) and post-monsoon season (10) was less than the critical value (> 100), indicating low-level pollution. The average value (2.58, 0.63) of the Nemerow Index (NI) has indicated moderate contamination in the monsoon and low-level contamination during the post-monsoon season. The study revealed the carcinogenic health risks (due to Cr, Cd and Pb) and non-carcinogenic risks across all the age groups, especially among children, followed by adults and infants in both the seasons.

期刊介绍: Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
