摘要
碘是人体必需的一种微量元素。但是由于碘在自然环境中的分布不均匀,不同地区人群的碘摄入会产生缺乏或过量的现象,进而引起一系列的疾病。我国是世界上碘缺乏最严重的国家之一,因此实施食品及相关水体中碘含量的监测是一项长期的基本任务。然而碘在自然环境中的存在形式复杂,不同形态碘的生物有效性及毒性差异很大,因此开展不同形态碘含量的监测对于科学、准确评估人群的碘摄入具有重要意义。本文总结了近十多年来碘形态分析技术的发展,比较了各种前处理技术及分离分析技术的优缺点及适用范围,以期为相关科研工作者开展进一步的工作提供参考。
Iodine is an essential trace element for human body.However,due to the uneven distribution of iodine in the natural environment,the iodine intake of people in different regions will produce a lack or excess phenomenon,thus causing a series of diseases.China is one of the countries with the most serious iodine deficiency in the world,so monitoring iodine content in food and related water is a long-term basic task.However,the existing forms of iodine in the natural environment are complex,and the bioavailability and toxicity of different forms of iodine vary greatly.Therefore,monitoring the content of different forms of iodine is of great significance for scientific and accurate assessment of iodine intake of the population.This paper summarized the development of iodine speciation analysis technology in the past 10 years,and compared the advantages,disadvantages and application scope of various pretreatment technologies and separation analysis technologies,so as to provide reference for relevant scientific researchers to carry out further work.
