为探明湘西花垣主要地表河流水重金属污染的程度,评估河流地表水的健康风险,于2016年8月、12月分别采取花垣县主要河流花垣河与兄弟河11个点位地表水水样,对水样中重金属铅(Pb)、锌(Zn)、铬(Cr)、铜(Cu)、铁(Fe)、镍(Ni)进行监测,并采用美国环境保护局(USEPA)推荐的健康风险评价模型,对花垣县主要地表河流水中的重金属进行健康风险评价.结果显示,研究区地表河流水中Pb、Zn、Cr、Cu、Fe与Ni的含量分别为2.57×10~(-3)、4.66×10~(-4)、1.65×10~(-3)、6.27×10~(-4)、0.19、8.50×10~(-4) mg/L.地表河流水中重金属产生的健康风险较高,化学致癌物(Cr)的健康风险值高于化学非致癌物质(Pb、Zn、Cu、...

To study heavy metal pollution and assess the health risk of river water in Huayuan County, Xiangxi, Hunan Province, 11 water samples were collected from the Huayuan River and Brother Rivers in August and December 2016. Heavy metal (Pb, Zn, Cr, Cu, Fe, and Ni) concentrations were determined from the samples. The health risk assessment model recommended by the U.S. Environmental Protection Agency (USEPA) was applied to assess the health risk of heavy metals in the main surface waters of Huayuan County. The results indicated that the concentratio...
