天然水中碘浓度与动植物中的含量关系密切,是碘缺乏病监测的一项重要辅助指标,曾有材料指出水碘须于24小时内测定,但在偏僻地区往往不易做到,有人对水样存放于冰箱或室温不同时间进行观察,又因样本含量太小和未作统计学分析,使其参考价值受限。对此我们进行了初步分析观察。 Natural water, iodine concentration and animal and plant content is closely related to iodine deficiency disorders monitoring is an important ancillary indicators, there have been materials that should be determined within 24 hours of water iodine, but often difficult to do in remote areas, some people on the water Samples stored in the refrigerator or at room temperature at different times for observation, but also because the sample is too small and not for statistical analysis, the reference value is limited. We conducted a preliminary analysis of this observation.
