摘要
碘是人体新陈代谢和生长发育的必需微量元素,化学教科书中缺乏对于科学补碘知识的基本介绍,问卷调查发现大部分师生对科学补碘知识了解得并不完善。梳理补碘知识可知:成人碘推荐摄入量为120μg·d^(-1),最高耐受量为600μg·d^(-1),水碘含量低于40μg·L^(-1)的碘缺乏地区要食用加碘盐,高于100μg·L^(-1)的高碘地区要食用无碘盐,经常食用富含碘元素食物的人群即使在碘缺乏地区也要减少食用加碘盐。据此,在教学过程和教材内容中提出科学补碘的相关建议,以提高师生补碘的认知水平,并培养学生对社会相关热点问题做出正确价值判断的能力。
Iodine is an essential microelement for human metabolism and growth.Current chemical textbooks are lack of basic introduction to knowledge of scientific iodine supplementation.Questionnaire survey found that most teachers and students do not have a complete understanding of scientific knowledge of iodine supplementation.Concluded from previous literatures,following points of iodine supplementation are essential:the recommended amount of iodine intake for adult is 120μg:d^(-1);the maximum tolerable amount of intake is 600μg·d^(-1);iodized salt should be consumed in iodine-deficient areas where water iodine is below 40μg·L^(-1),while iodine-free salt is suggested for areas above 1ooμg·L^(-1);people who regularly ingest iodine-rich food should cut back on iodized salt even in iodine-deficient areas.Therefore,advices on scientific iodine supplementation are put forward in the teaching process and textbook content,so as to improve teachers'and students'cognition level of iodine supplementation and cultivate students'ability to make correct value judgment on related hot social issues.
