地下水是鲁西平原主要的供水水源，系统查明地下水中氟碘化物分布、成因及对人体的健康风险，可以为科学合理利用该地区地下水资源提供重要依据。以鲁西平原腹地聊城市为研究区，系统分析了地下水中氟碘化物的空间分布、水化学特征，同时对研究区氟碘化物的生态风险预警及人体健康风险进行了评价，结果表明:研究区地下水中高氟、高碘水样分别占15.00%、73.33%，其中高氟地下水在阳谷县、莘县和冠县零星分布，高碘地下水分布广泛，碘化物污染相对严重区域地处京杭大运河沿线及其河水迁移处;地下水中氟碘化物质量浓度分布主要受矿物溶解及蒸发作用影响;地下水碘化物处于轻度预警等级，冠县部分区域和京杭大运河沿线地下水氟碘化物处于中度、重度预警等级;地下水氟碘化物对人体产生的潜在非致癌健康风险主要来源于饮水途径，且对儿童的潜在非致癌健康风险显著高于成人的。
Abstract：Groundwater is the main water source in the Luxi Plain. A systematic investigation of the distribution,origins,and human health risks of fluoride and iodide in groundwater systematically can provide a crucial foundation for the scientific and rational utilization of groundwater resources in this area. In this study,the hinterland of the Luxi Plain,Liaocheng City,was selected as the study area. The spatial distribution and hydrochemical characteristics of fluoride and iodide in groundwater were analyzed systematically. Moreover,the ecological risk early warning and human health risks of fluoride and iodide in the study area were evaluated. Results show that the samples with high-fluoride and high-iodide accounted for 15.00% and 73.33%,respectively. High-fluoride groundwater was scatteredly distributed in Yanggu County,Shen County,and Guan County. The areas with relatively severe iodide pollution are located along the Beijing-Hangzhou Grand Canal and in regions affected by its water flow. Mineral dissolution and evaporation are identified as the primary factors influencing fluoride and iodide concentrations. The groundwater iodide is at a mild warning level,while fluoride and iodide in some areas of Guanxian County and along the Beijing-Hangzhou Grand Canal are at moderate to severe warning levels. The potential non-carcinogenic health risks to humans from fluoride and iodide in groundwater primarily stem from drinking water exposure,with the potential risks being significantly higher for children than for adults.
