摘要
目的调查河北省所有县(市、区,以下简称县)居民生活饮用水碘含量,明确河北省水碘分布特征和水源性高碘地区的分布范围。方法2017年,在河北省所有县,以乡(镇、街道办事处,以下简称乡)为单位,根据不同供水方式采集水样检测碘含量;在水碘中位数≥10μg/L的乡,以村(居委会,以下简称村)为单位采集水样检测碘含量。结果共对168个县的2199个乡进行水碘调查,乡水碘中位数范围为0.0~1113.7μg/L。其中1579个乡水碘中位数<10μg/L,占总体的71.81%;≥10μg/L的乡有620个。水碘中位数≥10μg/L的乡含监测村数17930个,其中水碘<10μg/L的村有2312个(12.89%),≥100μg/L的村有6104个(34.04%),≥300μg/L的村有1577个(8.80%)。高碘水源主要分布在沧州、邯郸、邢台、衡水和廊坊5个市的39个县中,呈片状或点状分布。结论水源性高碘地区在河北省分布范围广泛,呈片状或点状分布。
Objective To master the iodine content of drinking water in all counties(cities,districts)and clarify the distribution characteristics of water iodine and the distribution range of water-borne high iodine areas in Hebei Province.Methods In all counties(cities,districts)of Hebei Province,water samples in townships(towns,street office,hereinafter referred township)were collected according to different water supply methods to detect iodine content in 2017;in townships with a median of water iodine≥10μg/L,the administrative village(neighborhood committee,hereinafter referred village)was used as a unit to collect water sample to detect iodine content.Results A total of 2199 townships in 168 counties(cities,districts)were surveyed for water iodine.The median range of water iodine of the townships was 0.0-1113.7μg/L.The median of water iodine in 1579 townships was<10μg/L,accounting for 71.81%of the total;the number of townships with water iodine of 10μg/L or more was 620.The village water iodine survey was carried out in the townships with water iodine of 10μg/L or more,the number of villages monitored was 17930.The number of villages with a median of water iodine of less than 10μg/L was 2312(12.89%),and there were 6104 villages with water iodine of 100μg/L or more,accounting for 34.04%.The number of villages with median of water iodine≥300μg/L was 1577(8.80%).The water-borne high iodine areas in Hebei Province were distributed in 39 counties(cities,districts)of five cities,namely,Cangzhou,Handan,Xingtai,Hengshui and Langfang.They were mainly distributed in sheet shape or spot shape.Conclusion The water-borne high iodine areas in Hebei Province are widely distributed,in the form of sheet or spot.
