食盐是人们日常生活的必需品,我国缺碘地区市售的食盐都必须是加碘食盐,简称碘盐。目前我国有些地方的不法之徒销售无碘私盐来冒充碘盐,这不仅使国家每年丧失上亿元的税收,而且使人民群众的身体健康受到严重的缺碘伤害。因此,对碘盐的研讨是一个十分重要的现实问题。 Salt is the daily necessities of people’s daily necessities, iodine-free areas of China’s commercial salt must be iodized salt, referred to as iodized salt. At present, unscrupulous people in some parts of our country sell iodine-free salt to pretend to be iodized salt, which not only deprives the country of hundreds of millions of yuan of tax revenue every year but also harms the people’s health from being seriously iodine deficiency. Therefore, the study of iodized salt is a very important practical problem.
