太康县水源水碘含量调查分析

The Investigation and analysis of iodine content in water in Taikang County

目的太康县为高碘毗邻地区,为掌握县城居民生活饮用水中碘含量的情况,给碘缺乏病防治提供依据。对辖区范围内4788份居民生活饮用水水碘含量进行了检验。方法按照《河南省高碘毗邻地区水碘普查及人群碘营养水平调查方案》要求采集样品,硫酸-高铈催化比色法进行测定。结果水碘含量在(1~10)μg/L110份;(10~100)μg/L3993份;(100~150)μg/L 685份,中位数73.4μg/L。结论按照成人每昼夜摄入水2 L^3L水平计算,每日碘摄入量200μg左右,根据世卫组织关于人体碘摄入量的最新推荐值,我县大部分为适碘区[3]。

Taikang County is near the high iodine areas. In order to master the situation of iodine content in drinking water among my county residents,and provide the basis for disease prevention of iodine deficiency,drinking water iodine content is tested within the scope of 4 788 people. Methods According to the ＂Henan province high iodine areas adjacent to the water iodine and iodine nutrition level census survey plan＂ requirements,samples are collected and measured by Sulfuric acid- catalyzed cerium colorimetric method. Results the water iodine content in 1-10 μ g/L is110;10-100 μ g/L 3993;100-150 μ g/L 685;the median was 73.4 μ g/L. Conclusion according to the 2-3L level calculation of adult intake of water every day and night,daily iodine intake is about 200 μg. Regarding the latest recommended iodine value of human intake by the World Health Organization,my county belongs to the most adaptive iodine area.
