今年3月.山东省单县某小学突然相继发生约500名学生中毒。据调查是该县卫生防疫站副站长私自推销大量口服碘钙营养片引起的。同期,该省宁阳县另一小学也有200多名学生中毒。上述地区为高碘区,身为卫生防疫站领导,为了获取较大利润,给孩子大量补碘而造成碘中毒,表面看是无专业知识的笑话,但类似未造成严重后果的强行向小学、幼儿园推销碘剂保健品的却不是个别的。所以,它是必然中的偶然。他们除为非法获利和无视食品法观念外,就是营养知识贫乏得可怜。为此,有必要重申有关碘的卫生知识,以防此类事件重演。一、碘的作用及供给量标准碘是最重要的营养素之一。人体每公斤体重约含0.5毫克,70—80%存在甲状腺中,含量甚微,其作用极大。碘的功能主要是对状腺功能的影响。 1.缺碘可限制甲状腺素的制造,使人体基础代谢 In March this year, a primary school in Shan County, Shandong Province suddenly and suddenly occurred about 500 students poisoning.

For this reason, it is necessary to reiterate the hygienic knowledge on iodine to prevent such incidents from recurring. First, the role of iodine and supply standards Iodine is one of the most important nutrients. Human body weight per kg of about 0.5 mg, 70-80% of the thyroid, the content is minimal, its great effect. The function of iodine is mainly the effect on the function of the glandular gland. 1.
