目的：调查宁津县居民饮用水碘含量情况，为科学指导补碘提供依据。方法2009—2010年和2013—2014年两次以自然村为调查单位，每村采集1～3份饮用人数最多的水源样品。用砷铈催化分光光度法检测水碘。结果2009—2010年共收集水样1686份，宁津县水碘中位数为126．6μg／L ，范围在0．2～734．2μg／L之间，2013—2014年共收集水样621份，水碘中位数为2．58μg／L ，范围在0．2～6．78μg／L之间。结论宁津县居民饮水含碘量在时间和空间上均差异巨大，建议根据不同水碘类型给予相应的防治措施。

Objective To investigate the iodine content in drinking water of Ningjin County ,in order to provide scientific guidance for iodine supply .Methods In the monitored villages ,1 to 3 drinking water samples were collected during 2009—2010 and 2013 -2014 .The iodine content in the samples was measured using arsenic‐cerium catalytic speetrophotometry .Results During 2009‐2010 ,a total of 1 686 water samples were collected and the median was 126 .6 μg/L ,ranging of 0 .2~734 .2 μg/L;during 2013—2014 ,a total number of 621 water samples were collected and the median was 2 .58 μg/L , ranging 0 .2 ~ 6 .78 μg/L .Conclusion The iodine content in drinking water from Ningjin County varies greatly in both time and space , suggesting that different prevention measures should be introduced to different types of water iodine .
