摘　　要：目的调查山西省晋中市水碘分布情况,为科学划定不同水碘含量地区范围提供科学依据。方法2024年3—8月,采用横断面调查方法,在全市11个县(区、市,简称县),以行政村(社区,简称行政村)为单位,以2017年全市生活饮用水碘含量调查结果为本底,核实县、乡镇、行政村的名称及行政区划变动情况,调查人口资料、水源信息和供水工程运行情况,另采用10%抽样法采集生活饮用水水样,硫酸铈催化分光光度法检测水碘含量。结果共调查2181个行政村的2402个集中供水工程,全部正常运转。全市水碘中位数为2.43μg/L,范围为0.15~556.45μg/L。水碘含量<40、40~100、>100μg/L地区覆盖的行政村数和人口数分别为1990个、2841752人,153个、372085人,38个、75493人。结论按照水碘含量划分,晋中市碘缺乏、适碘、高碘地区并存,但碘缺乏地区居多,仍需继续落实食盐加碘措施。高碘地区需继续推进改水降碘和供应未加碘盐措施落实,做好重点地区、重点人群的防病知识宣传,引导群众科学补碘,有效控制高碘危害。Objective To find out the distribution of water iodine in Jinzhong City,Shanxi Province,and provide scientific basis for scientifically delimiting the distribution range of different water iodine level areas.Methods From March to August 2024,by using a cross-sectional survey method,the administrative villages(communities,abbreviated as administrative villages)were used as units in 11 counties(districts,cities,abbreviated as counties)of the city to verify the changes in the names and administrative divisions of counties,townships,and administrative villages based on the survey results of iodine content in drinking water in the city in 2017.Population data,water source information,and water supply project operation were investigated,and 10%sampling method was used to collect drinking water samples.Cerium sulfate catalytic spectrophotometry was used to test water iodine level.Results A total of 2402 centralized water supply projects in 2181 administrative villages were investigated and all were operating normally.The median iodine concentration in the city's water was 2.43μg/L,ranging from 0.15 to 556.45μg/L.The number of villages and population covered by water iodine level of<40,40-100,and>100μg/L was 1990 villages and 2841752,153 villages and 372085,38 villages and 75493,respectively.Conclusions According to the classification of water iodine standards,Jinzhong City presents a coexistence of iodine deficiency,adequate iodine,and high iodine areas,with iodine deficiency areas still being the main focus.Therefore,it is necessary to continue implementing salt iodization measures.Areas with high iodine levels need to continue to promote the implementation of measures to improve water quality,reduce iodine levels,and supply non iodized salt.Efforts should be made to promote disease prevention knowledge among key areas and populations,guide the public to scientifically supplement iodine,and effectively control the hazards of high iodine.
