摘要
地下水砷污染对环境和人体健康的影响已经引起人们的广泛关注.本研究综合应用地理信息系统(GIS)技术和健康风险评估方法,对 1980-2022 年的相关文献进行分析,探讨了中国地下水砷浓度的时空分布特征及其对健康的潜在风险.研究结果显示,我国地下水砷浓度在时间上的变化趋势较弱,但在空间分布上呈现强烈的变异性,特别是在华北、东北和华中的局部地区检测出较高的地下水砷浓度.然而,我国大部分地区现有的地下水砷浓度检测数据均低于世界卫生组织(WHO)的饮用水标准.基于现有地下水砷浓度数据进行健康风险评估,发现不同人群由地下水砷污染引起的健康风险逐年降低,目前总体处于可接受范围内,但北方部分地区仍存在较高的健康风险.
Abstract
The impacts of groundwater arsenic contamination on the environment and human health have attracted widespread attention.In this study,we comprehensively applied geographic information system(GIS)technology and health risk assessment methods to analysis relevant literature from 1980 to 2022,and explored the spatial and temporal distribution characteristics of arsenic concentration in groundwater in China,as well as its potential risk to health.The results show that the temporal trend of groundwater arsenic concentration in China is weak,but the spatial distribution shows strong variability,especially in the local areas of North,Northeast and Central China where higher groundwater arsenic concentrations are detected.However,the existing groundwater arsenic concentration detection data in most areas of China are lower than the World Health Organization(WHO)drinking water standards.A health risk assessment based on the existing groundwater arsenic concentration data found that the health risk caused by groundwater arsenic contamination in different populations has been decreasing year by year,and is now generally within an acceptable range,but a higher health risk still exists in some areas of northern China.
