本研究是一项调查的空间化学，污染源（使用多元统计），和健康风险评估所产生的消费地下水污染的微量和有毒元素的Chhaprola工业区，高塔姆佛纳加尔，北方邦，印度。在这项研究中，33管井水样品进行了分析，28个元素使用ICP-OES。其中Al、As、B、Cd、Cr、Mn、Pb和U等微量和有毒元素的含量超过了相应的WHO（2014）指南和BIS（2012）标准，而其他分析元素的含量低于这些标准。对背景伽马和β辐射水平进行了观测，发现其在可接受的限度内。多变量统计PCA（解释82.07%的累计6个因素）和CA表明（混合起源），自然和人为活动，如工业废水和农业径流是负责在研究区的地下水水质退化。在本研究区，成人饮水量为3.0 L（中位数）时，每天从饮水中分别摄入Al、As、B、Cd、Cr、Mn、Pb、U 39、1.94、1461、0.14、11.1、292.6、13.6、23.5 μ g。As、B、Al、Cr、Mn、Cd、Pb和U的危害商数（HQ）值在少数地点超过了安全限值1，而危害指数（HI）在约30%的样品中观察到> 5，这表明如果地下水被消耗，这些管井对当地居民的潜在健康风险。(C)2016爱思唯尔有限公司版权所有
This study is an investigation on spatio-chemical, contamination sources (using multivariate statistics), and health risk assessment arising from the consumption of groundwater contaminated with trace and toxic elements in the Chhaprola Industrial Area, Gautam Buddha Nagar, Uttar Pradesh, India. In this study 33 tubewell water samples were analyzed for 28 elements using ICP-OES. Concentration of some trace and toxic elements such as Al, As, B, Cd, Cr, Mn, Pb and U exceeded their corresponding WHO (2014) guidelines and BIS (2012) standards while the other analyzed elements remain below than those values. Background gamma and beta radiation levels were observed and found to be within their acceptable limits. Multivariate statistics PCA (explains 82.07 cumulative percent for total 6 of factors) and CA indicated (mixed origin) that natural and anthropogenic activities like industrial effluent and agricultural runoff are responsible for the degrading of groundwater quality in the research area. In this study area, an adult consumes 3.0 L (median value) of water therefore consuming 39, 1.94, 1461, 0.14, 11.1, 292.6, 13.6, 23.5 mu g of Al, As, B, Cd, Cr, Mn, Pb and U from drinking water per day respectively. The hazard quotient (HQ) value exceeded the safe limit of 1 which for As, B, Al, Cr, Mn, Cd, Pb and U at few locations while hazard index (HI) > 5 was observed in about 30% of the samples which indicated potential health risk from these tubewells for the local population if the groundwater is consumed.
