摘　　要：目的调查山东省生活饮用水水碘分布情况,为重新划定不同类型水碘地区,采取针对性防治措施和科学调整干预策略提供依据。方法2017年,以乡镇(街道办,以下简称乡镇)为单位在全省开展水碘分布调查。另外,对本次或既往调查发现的水碘>10μg/L的乡镇,以行政村(居委会,以下简称行政村)为单位开展调查。采用砷铈催化分光光度法检测水碘。结果共调查1844个乡镇,水碘中位数为9.2μg/L。其中水碘<10μg/L的乡镇有969个,占52.55%;10~40μg/L的乡镇有489个,占26.52%;>40~100μg/L的乡镇有139个,占7.54%;>100μg/L的乡镇有247个,占13.39%。在水碘中位数>10μg/L的乡镇中共调查37073个行政村,收集有效数据36690个。其中,水碘<10μg/L的行政村有5531个,占15.07%;10~40μg/L的行政村有17350个,占47.29%;>40~100μg/L的行政村有4859个,占13.24%;>100μg/L的行政村有8950个,占24.39%。结论山东省大部分地区为碘缺乏地区(水碘<10μg/L),水源性高碘地区(水碘>100μg/L)和"适碘"地区(水碘10~100μg/L)均有一定比例的存在,且水碘存在动态调整的可能,下一步应继续加强水碘和人群碘营养动态监测,为碘盐供应策略调整提供数据支持。Objective To investigate the distribution of iodine in drinking water in Shandong Province,and to provide a basis for redefining different types of iodine in drinking water,adopting specific prevention measures and scientifically adjusting intervention strategies.Methods In 2017,a survey on the distribution of water iodine in the whole province was carried out in townships(street offices,hereinafter referred to as townships).In addition,the administrative villages(neighborhood committees,hereinafter referred to as administrative villages)shall be taken as the units for the investigation of townships with a median water iodine of>10μg/L or more found in this or previous surveys.Arsenic-cerium catalytic spectrophotometry was used to detect water iodine.Results A total of 1844 townships were surveyed,with a median water iodine of 9.2μg/L.Among them,there were 969 townships with water iodine of less than 10μg/L,accounting for 52.55%.From 10 to 40μg/L,489 townships,accounting for 26.52%;There were 139 townships with>40-100μg/L,accounting for 7.54%;there were 247 townships of>100μg/L,accounting for 13.39%.A total of 37073 administrative villages were surveyed in the townships with a median water iodine of>10μg/L,and 36690 were collected with valid data.Among them,5531 villages with water iodine<10μg/L,accounting for 15.07%;there were 17350 villages with 10-40μg/L,accounting for 47.29%;there were 4859 villages of>40-100μg/L,accounting for 13.24%;the number of villages>100μg/L was 8950,accounting for 24.39%.Conclusions In Shandong Province,most areas are iodine deficiency area(water iodine<10μg/L),waterborne high iodine areas(water iodine>100μg/L)and"optimal iodine"(water iodine 10-100μg/L)regions exist,and there is the possibility of dynamic adjustment of water iodine.In the next step,the dynamic monitoring of iodine nutrition in water and population should be strengthened to provide data support for the adjustment of iodized salt supply strategy.
