摘　　要：目的了解山西省外环境水碘分布情况，为缺碘、适碘或高碘地区的重新划定及实施科学补碘提供依据。方法2012—2016年，在山西省11个市119个县（市、区），以行政村（居委会）为单位，采集1～5份饮用水样品，采用砷铈催化分光光度法检测水碘含量。地区划定标准：水碘含量〈10μg／L为缺碘地区，水碘含量〉100μg／L为高碘地区。结果共调查119个县（市、区）、1362个乡（镇）、26213个行政村（居委会），覆盖2850．94万人。共采集水样32766份，水碘中位数为5．2μg／L。全省水碘〈10μg／L的村有18199个，占69．4％（人口数1812．17万人，占调查总人121数的63．6％）；10-〈50μg/L的村有6471个，占24．7％（人口数787．44万人，占27．6％）；50-〈100μg／L的村有1166个，占4．4％（人口数181．46万人，占6．4％）；≥100μg／L的村有377个，占1．4％（人口数69．87万人，占2．5％）。被调查的1362个乡（镇）中，71．1％（969个）的乡（镇）水碘中位数〈10μg／L，24．2％（330个）的乡（镇）水碘中位数在10～〈50μg／L，3．4％（46个）的乡（镇）水碘中位数在50～〈100μg／L，1．2％（17个）的乡（镇）水碘中位数≥100μg／L；119个县（市、区）中，90个（占75．6％）县（市、区）水碘中位数〈10μg／L，26个（占21．8％）县（市、区）水碘中位数在10～〈50μg／L。结论山西省大部分地区（或居住人口）为碘缺乏地区，其余各地区外环境水碘含量各异，对水碘含量不同地区应采用不同的补碘或降碘措施。Objective To understand the distribution of water iodine in the external environment of Shanxi Province, and to provide a basis for redefining and implementation of scientific iodine supplementation in iodine deficiency, iodine adequate or iodine high areas. Methods In 2012 - 2016, administrative villages （neighborhood committees） in 119 counties （cities, districts） in 11 cities of Shanxi Province were selected as the investigation units, and 1 to 5 drinking water samples were collected. Water iodine content was detected using arsenic-cerium catalytic spectrophotometry. Areas standard was designated： water iodine content 〈 10 μg/L as iodine deficiency areas, 〉 100 μg/L as iodine high areas. Results A total of 26 213 administrative villages （neighborhood committees） of 1 362 townships （towns） of 119 counties （cities, districts） were surveyed, covering 2 850.94 ten thousand people. A total of 32 766 water samples were collected and the median iodine was 5.2μg/L. There were 18 199 villages with water iodine 〈 10 μg/L, accounting for 69.4% （covering 1 812.17 ten thousand people, accounting for 63.6%）, 6 471 villages with water iodine 10 - 〈 50 p.g/L, accounting for 24.7% （covering 787.44 ten thousand people, accounting for 27.6 %）, 1 166 villages with water iodine 50 - 〈 100 μg/L, accounting for 4.4% （covering 181.46 ten thousand people, accounting for 6.4% ）, 377 villages with water iodine 100 μg/L, accounting for 1.4% （covering 69.87 ten thousand people, accounting for 2.5%）. In 1 362 townships （towns）, 71.1% （969） water iodine median was 〈 10 μg/L, 24.2% （330） water iodine median was in 10 - 〈 50 μg/L, 3.4% （46） water iodine medianwas in 50 - 〈 100 μg/L, and1.2%（17） water iodine median was - 100 μg/L. In 119 counties（cities, districts）, there were 90 counties （accounting for 75.6%） with the water median 〈 10μg/L, there were 26 counties （accounting for 21.8%） with the water median 10 - 〈 50μg/L.
