摘　　要：目的动态了解江苏省区域供水方式改变后(2020年)居民生活饮用水碘含量变化情况。方法2020年6-10月,在江苏省2017年居民饮用水碘含量调查中水碘中位数≥40μg/L的行政村开展水碘含量调查。调查范围主要涉及淮安、连云港、宿迁、盐城、徐州5个设区市21个县(市、区)的1537个行政村。按照《碘缺乏地区和适碘地区的划定》(WS/T 669-2020)标准,水碘中位数为40~100μg/L的行政村为适碘地区。水碘检测采用国家碘缺乏病参照实验室推荐的"适合缺碘及高碘地区水碘检测的方法"。结果2020年共监测江苏省1498个行政村,均已实现集中供水;行政村水碘中位数为35.2μg/L,最小值为1.2μg/L,最大值为606.7μg/L。其中,206个行政村水碘中位数<10μg/L,占13.75%(206/1498);610个行政村水碘中位数为10~<40μg/L,占40.72%(610/1498);635个行政村水碘中位数为40~100μg/L,占42.39%(635/1498);47个行政村水碘中位数>100μg/L,占3.14%(47/1498)。除宿迁市宿城区、徐州市新沂市和鼓楼区、淮安市清江浦区和盱眙县、连云港市灌南县以外,其余15个县(市、区)的行政村2020年水碘中位数均较2017年显著下降,差异均有统计学意义(均P<0.05)。结论2020年供水方式改变后,江苏省大部分监测县(市、区)的行政村水碘含量较2017年显著下降。Objective To dynamically observe the changes in iodine level in residents'drinking water after the change of regional water supply mode(2020)in Jiangsu Province.Methods The survey of water iodine level was conducted from June to October 2020 in administrative villages of Jiangsu Province with a median water iodine≥40μg/L in 2017.The survey mainly covered 1537 administrative villages in 21 counties(cities and districts)of 5 cities,including Huaian City,Lianyungang City,Suqian City,Yancheng City,and Xuzhou City.Based on the standard of"Definition and Demarcation of Iodine Deficient Areas and Iodine Adequate Areas"(WS/T 669-2020),the administrative villages with a median water iodine of 40-100μg/L were classified as iodine adequate areas.Water iodine testing was conducted using the"Method for Water Iodine Testing in Iodine Deficient and High Iodine Areas"recommended by the National Reference Laboratory for Iodine Deficiency Disorders.Results Totally 1498 administrative vilages in Jiangsu Province were monitored in 2020,all of which had centralized water supply.The minimum value of water iodine in all administrative villages was 1.2μg/L and the maximum value was 606.7μg/L,and the median water iodine was 35.2μg/L.Among them,206 administrative villages had median water iodine<10μg/L,accounting for 13.75%(206/1498);610 administrative villages had median water iodine from 10 to<40μg/L,accounting for 40.72%(610/1498);635 administrative villages had median water iodine from 40 to 100μg/L,accounting for 42.39%(635/1498);and 47 administrative villages with median water iodine>100μg/L,accounting for 3.14%(47/1498).Except for Sucheng District in Suqian City,Xinyi City and Gulou District in Xuzhou City,Qingjiangpu District and Xuyi County in Huaian City,and Guannan County in Lianyungang City,the median water iodine in the administrative villages of the remaining 15 counties(cities and districts)in 2020 decreased significantly compared to 2017,and the differences were statistically significant(P<0.05).Conclusion After
