  • 摘要: 地下水作为海岸带地区重要的饮用水源，其水质与人类健康息息相关，因此研究海岸带地下水水质有重要的现实意义.本次研究于秦皇岛海岸带地区采集了25个地下水样品，并对其重金属（As、Cr、Cd、Ni、Cu、Zn、Pb）含量进行了测试，并以测试结果为基础进行了健康风险评价.结果表明，研究区地下水重金属含量均值从高到底排序为Zn > Cu > As > Ni > Pb > Cr > Cd.所有水样的重金属含量均低于地下水质量标准（GB/T 14847-2017）Ⅲ类水及WHO限值.地下水中的Cu、Zn主要来源于工业活动，Ni、Cd、Pb受工业活动和海水入侵的共同影响，As、Cr主要来源于矿物溶解.致癌重金属（As、Cd、Cr）产生的健康风险远超非致癌重金属（Zn、Cu、Ni、Pb）.致癌重金属的健康风险排序为Cr > As > Cd，其中Cr和As的健康风险均值分别为4.73×10-6 a-1和1.7×10-6 a-1，占比71.1%和25.5%，表明Cr和As是研究区地下水中值得关注的重金属.致癌重金属与非致癌重金属产生的健康风险均低于国际放射防护委员会和美国国家环境保护局的最大可接受水平.空间分布上，健康风险自昌黎县的2.86×10-5 a-1向北逐渐降低到秦皇岛市的1.26×10-6 a-1.
    Abstract: As an important drinking water source in coastal areas, groundwater quality is closely related to human health. Therefore, it is of great practical significance to study groundwater quality in coastal areas. In this study, 25 groundwater samples were collected in the coastal zone of Qinhuangdao, the content of heavy metals (As, Cr, Cd, Ni, Cu, Zn, Pb) was tested, and the health risk assessment was conducted based on the test results. The results showed that the average heavy metal content in the groundwater was ordered from high to low as Zn > Cu > As > Ni > Pb > Cr > Cd. The heavy metal content of all water samples is lower than the groundwater quality standard (GB/T 14847-2017) Class Ⅲ and WHO limits. The health risks from carcinogenic heavy metals (As, Cd, Cr) far exceed those from non-carcinogenic heavy metals (Zn, Cu, Ni, Pb). The health risks of carcinogenic heavy metals were ranked as Cr > As > Cd, and the average health risks of Cr and As were 4.73×10-6 a-1 and 1.7×10-6 a-1, respectively, accounting for 71.1% and 25.5%, indicating that Cr and As were the heavy metals worthy of attention in the groundwater of the study area. The health risks from both carcinogenic and non-carcinogenic heavy metals are lower than the maximum acceptable levels of the International Commission on Radiological Protection and the U.S. Environmental Protection Agency. In terms of spatial distribution, the health risk gradually decreased from 2.86×10-5 a-1 in Changli to 1.26×10-6 a-1 in Qinhuangdao. The Cu, Zn, and Pb in groundwater may come from industrial wastewater, Ni and Cd may come from industrial dust, and As and Cr may come from mineral components in soil or rocks. In addition, seawater intrusion may also affect the heavy metal content in groundwater.

摘要: 地下水作为海岸带地区重要的饮用水源，其水质与人类健康息息相关，因此研究海岸带地下水水质有重要的现实意义.本次研究于秦皇岛海岸带地区采集了25个地下水样品，并对其重金属（As、Cr、Cd、Ni、Cu、Zn、Pb）含量进行了测试，并以测试结果为基础进行了健康风险评价.结果表明，研究区地下水重金属含量均值从高到底排序为Zn > Cu > As > Ni > Pb > Cr > Cd.所有水样的重金属含量均低于地下水质量标准（GB/T 14847-2017）Ⅲ类水及WHO限值.地下水中的Cu、Zn主要来源于工业活动，Ni、Cd、Pb受工业活动和海水入侵的共同影响，As、Cr主要来源于矿物溶解.致癌重金属（As、Cd、Cr）产生的健康风险远超非致癌重金属（Zn、Cu、Ni、Pb）.致癌重金属的健康风险排序为Cr > As > Cd，其中Cr和As的健康风险均值分别为4.73×10-6 a-1和1.7×10-6 a-1，占比71.1%和25.5%，表明Cr和As是研究区地下水中值得关注的重金属.致癌重金属与非致癌重金属产生的健康风险均低于国际放射防护委员会和美国国家环境保护局的最大可接受水平.空间分布上，健康风险自昌黎县的2.86×10-5 a-1向北逐渐降低到秦皇岛市的1.26×10-6 a-1.
