目的　抽样调查微山湖区及运河沿岸居民饮用水中的碘含量。方法　在微山湖东西两岸及运河沿岸随机抽取水样若干份 ,用砷铈分光光度法测定其含量。结果　湖西区、湖东区、运河沿岸水碘均值分别为 170 μg/L、75 μg/L、30 μg/L ,呈正偏态分布。 结论　调查显示微山湖区及运河沿岸调查区内的地下水碘含量适中 Objective To sample the iodine content of drinking water in Weishan Lake area and residents along the canal. Methods Several samples of water samples were randomly collected along the banks of Weishan Lake and along the canal. The contents of arsenic and cerium were determined by spectrophotometry. Results The average values ​​of water iodine in the lake area, lake area and canal were 170 μg / L, 75 μg / L and 30 μg / L, respectively, showing a positive skewed distribution. Conclusion The survey shows that groundwater iodine content is moderate in the Weishan Lake area and the canal inland survey area
