【摘要】 目的 分析山东省淄博市生活饮用水中氟化物浓度水平，评估其健康风险。方法 收集2015-2020年山东省淄博市3 112份城乡饮用水样品，检测氟化物含量，采用我国WS/T 777-2021《化学物质环境健康风险评估技术指南》的环境健康风险评价模型，对山东省淄博市饮用水中的氟化物进行健康风险评价。结果 2015-2020年山东省淄博市3 112份生活饮用水中氟化物浓度为0.29(0.00,3.86)mg/L,超标率为1.00%。不同年度、不同水源类型的水氟浓度差异有统计学意义(P<0.01)。区域分布和Kriging插值显示，高青县饮用水氟化物浓度最高，且存在明显的高氟带。Spearman秩相关分析结果显示，饮用水中氟化物浓度与pH值、铝、铁、锰、氯化物、硫酸盐、溶解性总固体、耗氧量呈正相关(r_s为0.070～0.520,P<0.01),与硝酸盐氮、锌、总硬度呈负相关(r_s为-0.083～-0.411,P<0.01)。0～5岁儿童、6～17岁儿童和成人经饮用水途径暴露氟化物的平均健康风险值分别为0.25、0.15、0.19,最大健康风险分别为3.37、2.02、2.55。高青县饮用水氟化物平均和最高健康风险明显高于其他区县。结论 山东省淄博市饮用水氟化物总体健康风险较低，局部高水氟区域对居民尤其是0～5岁儿童存在健康风险。更多还原

【Abstract】 Objective To analyze the concentration of fluoride in drinking water in Zibo city, Shandong province, and evaluate the health risk. Methods A total of 3 112 samples of drinking water were collected from 2015 to 2020 in urban and rural areas in Zibo city, Shandong province.The fluoride content was detected to assess health risk of fluoride in drinking water by the the environmental health risk assessment model of “Technical Guideline for Environmental Health Risk Assessment of Chemical Exposure”(WS/T 777-2021). Results The fluoride concentration of 3 112 drinking waters was 0.29(0.00,3.86) mg/L from 2015 to 2020 in Zibo city, Shandong province,and the excess rate was 1.00%.The differences of water fluoride concentration in different years and in different water source types were statistically significant(P<0.01).The results of regional distribution and Kriging interpolation showed that Gaoqing county had the highest fluoride concentration in drinking water, and there was an obvious high fluoride zone.The results of Spearman rank correlation analysis showed that the concentration of fluoride in drinking water was positively correlated with pH,aluminum, iron, manganese, chloride, sulfate, total dissolved solids, and oxygen consumption(r_s:0.070～0.520,P<0.01),negatively correlated with nitrate nitrogen, zinc and total hardness(r_s:-0.083～-0.411,P<0.01).The average health risk values for children aged 0-5,children aged 6-17 and adults exposed to fluoride through drinking water were 0.25,0.15,and 0.19,respectively.The maximum health risks were 3.37,2.02,and 2.55,respectively.The average and highest health risks of fluoride in drinking water in Gaoqing county were significantly higher than those in other districts and counties. Conclusion The overall health risk of fluoride in drinking water is low in Zibo city, Shandong province, and local high water fluoride areas have health risks to residents, especially children aged 0-5 years.更多还原
