摘要
[目的]调查日照市居民饮用水中碘的含量,为碘缺乏病的防治提供基础资料与科学依据。[方法]在所辖区域范围内,以自然村(居委会)为单位进行水样采集,利用硫酸铈催化分光光度法对水样进行碘含量分析测定。[结果]各乡镇的水碘中位数均小于10μg/L;各区县间水碘频数分布差异有统计学意义(P<0.01);沿海乡镇与内陆乡镇水碘中位数分别为6.6μg/L与3.8μg/L,其频数分布差异有统计学意义。[结论]日照市属碘缺乏地区,日照市饮用水水碘的分布不均衡。
[Objective]To investigate the content of iodine in drinking water in Rizhao city. provide basic data and scientific basis for the control and prevention of iodine deficiency disorder. [Methods]Water samples were collected from the villages （neighborhood committee） in Rizhao area,the content of iodine in drinking water was analyzed and detcrmined with cerous sulfate catalysis spectrophotometric method. [Results]The median of iodine in drinking water of each town was less than 10 μg/L. There was a difference of the frequency distribution of iodine in drinking water in different towns and regions. The median of iodine in drinking water of coastal and inland towns was 6.6 μg/L and 3.8μg/L respectively, there was a difference of the frequency distribution between them （ P 〈0.01）. [Conclusion]Rizhao city was iodine deficiency area,iodine in drinking water is not well distributed.
