Abstract

Abstract:

The characteristics of heavy metal pollution in drinking water source of Guiyang and its potential hazards on human health were investigated. The mass concentrations of 12 heavy metals (Cd, Cr (VI), As, Hg, Cu, Fe, Mn, Mo, Co, Ni, Ba, V) in drinking water sources were monitored and analyzed from January to December in 2020. The potential health risks of heavy metals in drinking water sources were evaluated by using the environmental health risk assessment model recommended by US EPA. The results indicated that the order of the average mass concentrations of heavy metals in the water samples was as follows: Fe > Ba > Mo > Mn > Cr (VI) > Cu > V > Ni > As > Co > Cd > Hg. No heavy metals exceeded the limit specified by the drinking water health standards in China (GB 5749—2006). The mass concentrations of all heavy metals were lower than the specified limit of Grade I level in the environmental quality standards for surface water (GB 3838—2002). The spatial distribution characteristics of Cr (VI) and Cd showed no significant difference. Co, V, Hg and Ba were evenly distributed in space. The spatial distribution of As and Cu was higher in upstream than in downstream. The spatial distribution of Fe was higher in the downstream than in the upstream. Mn was higher in the downstream than in the upstream of Maotiao River basin. The distribution of Mo and Ni was consistent. Pearson correlation analysis of the concentrations of metal elements indicated that Hg and Ba, Co and Ni might have similar sources. Cr (VI) and Cd had no correlation with other heavy metals. Fe and Cu might come from different sources. The correlation between As, Mn, Mo and V was not high. The results of the health risk assessment indicated that children were more susceptible to the threat of heavy metal pollution than adults. The evaluation indexes of carcinogenic risk showed that Cr (VI) > As > Co > Cd. In terms of the non-carcinogenic risk evaluation indexes ranked from high to low, Mo > Cu > Fe > Ba > V > Hg > Mn > Ni. The evaluation value of carcinogenic risk of heavy metals was much higher than that of non-carcinogenic risk, and both were lower than the value recommended by the International Commission on Radiological Protection (ICRP). Cr (VI) was the main pollutant that causes health risk in the water environment in the study area, and should be taken as a priority index for risk control.

摘要：

为研究贵阳市7个集中式饮用水源地的重金属空间分布特征及重金属之间的相关性，并探讨饮用水源地的重金属污染对不同人群健康的潜在风险，于2020年1月—12月对7个饮用水源地水体中的Cd、Cr(VI)、As、Co、Fe、Hg、Mo、Ba、Cu、Mn、V和Ni这12种重金属质量浓度进行监测分析，利用US EPA推荐的环境健康风险评价模型对饮用水源地的潜在健康风险进行评价。分析结果表明，监测水体中重金属年平均质量浓度顺序为：Fe>Ba>Mo>Mn>Cr(VI)>Cu>V>Ni>As> Co>Cd>Hg，其平均质量浓度均未超过《生活饮用水卫生标准》（GB 5749—2006）规定的标准限值，且符合《地表水环境质量标准》（GB 3838—2002）Ⅰ类水质标准。空间分布特征表明，Cr(VI)、Cd和在空间上无明显变化趋势；Co、V、Ba和Hg在空间上分布较为均匀；As和Cu变化规律为上游质量浓度高于下游质量浓度；Fe为下游高于上游；Mn是在猫跳河流域下游质量浓度高于上游；Mo和Ni的空间分布特征比较一致。相关性分析表明，Cr(VI)和Cd与其他重金属不存在相关性；Hg和Ba、Co和Ni之间可能分别具有相似的来源或经历相同的迁移转化过程；Cu与Fe却是有着不同来源；As、Mn、Mo和V之间相关度不高。健康风险评价结果表明，对于不同的人群，儿童是比成年人更加容易受到重金属危害的群体。致癌风险评价指标从大到小依次为Cr(VI)>As>Co>Cd；非致癌风险评价指标从大到小依次Mo>Cu>Fe>Ba>V>Hg>Mn>Ni；重金属致癌风险评价值远高于非致癌风险评价值，两者均低于国际辐射防护委员会（ICRP）的推荐值；Cr(VI)是研究区域水环境产生健康风险的主要监测指标，应作为风险管控的优先指标。
