[目的]调查我省厦门市翔安区水源性高碘地区的分布和流行病学特征。[方法]以乡镇为单位进行抽样调查,以B超法测量儿童甲状腺容积,砷铈催化分光光度法测定水碘含量,过硫酸铵消化—砷铈催化分光光度法测定尿碘含量。[结果]该区水碘超过国家高碘地区标准的有17份水样(共采样检测596份);前炳村71口水井高碘井占16.9%,而且当地7~14岁学龄儿童的甲状腺肿大率和尿碘水平显著高于所在镇其它村;其它乡村检测5份水样中仅有1份水碘超标;当地井水碘含量与井深和到海边的距离有一定的关系。[结论]翔安区水源性高碘地区的分布,主要集中在新店镇前炳自然村,该村饮用水水井碘含量超标问题应引起重视。
[Objective] To investigate the distribution and epidemiological characteristics of water-rich iodine in Xiang’an District of Xiamen City. [Method] A sample survey was conducted on the basis of towns and townships. The children ’s thyroid volume was measured by B - ultrasonography, the water iodine content was determined by arsenic - cerium catalytic spectrophotometry, and the urinary iodine content was determined by ammonium persulfate digestion - arsenic and cerium catalytic spectrophotometry. [Result] There were 17 water samples (596 samples were sampled by common sampling) whose water iodine exceeded the national high iodine area standard. The iodine wells in 71 wells in Qianbing Village accounted for 16.9%, and the thyroid gland of school-age children aged 7-14 Swelling rate and urinary iodine were significantly higher than other villages in the town; only 1 out of 5 water samples tested in other villages exceeded the standard; the local well water iodine content had a certain relationship with well depth and the distance to the sea. [Conclusion] The distribution of high water iodine region in Xiang’an District was mainly concentrated in Qianbing Nature Village, Xindian Town. The problem of excessive iodine content in drinking water wells in this village should be paid more attention.
