目的：探讨在缺碘地区饮用水碘含量与井深的关系，为碘缺乏病防治提供科学依据。方法按《河北省居民饮用水水碘含量调查方案》对易县居民饮用水开展水碘监测，水碘检测采用水中碘的砷铈催化分光光度测定法。对饮用水碘含量与井深的关系进行相关性分析。结果井深<20.00 m，水碘均值在2.00μg/L以下。井深20.00~180.00 m，水碘均值在2.00μg/L以上。不同井深分组水碘均值均小于10μg/L。进行相关性分析，山地水碘含量与井深存在弱相关（r=0.165， P<0.05），其实际意义不大（r2=0.027）；丘陵和平原水碘含量与井深无明显相关性（r=-0.078、-0.076，P均>0.05）。结论在易县现有水井中，无论井深浅水碘含量均很低，饮水碘含量与井深无明显相关性。

Objective To explore the relationship between iodine content in drinking water and well depth in iodine deifciency area, and provide scientiifc basis for the development of prevention strategies to control iodine deifciency disorders. Methods According to the“Hebei Province resident drinking water iodine content survey program”, to carry water iodine monitoring for the residents of Yi County, water iodine contents were determined through arsenic cerium catalytic spectrophotometric method. Correlation analysis was carried out on the relationship between iodine content in drinking water and well depth. Results The water iodine average value of well depth was less than 20.00 m was 2.00μg/L or less. The water iodine average value of well depth between 20.00-180.00 m was 2.00μg/L or more. Iodine average value of different groups well depth was less than 10μg/L. By the correlation analysis, water iodine content and well depth existed the weak correlation in mountainous area(r=0.165, P<0.05), this situation had no true signiifcance(r2=0.027). There was no signiifcant correlation between water iodine content with well depth in hills and plain(r=-0.078, -0.076, P>0.05). Conclusion Water iodine content were very low, regardless of deep well or shallow well, and water iodine content has no correlation with well depth in existing wells in Yi County.
