碘是人体必需的微量元素,是合成甲状腺素的重要元素,人体碘元素的来源主要是水和食物,在无外来碘食物的条件下,水碘含量是衡量当地居民碘摄入量的重要指标~([1])。随着我市经济的快速发展以及农村改水改厕工程的实施,饮用水水源的改变和时间的变迁必将导致饮用水水碘含量的变化~([2])。内江市曾是四川省的碘缺乏地区之一,2010年实现了消除碘缺乏病。为全面了解目前我市居民生活饮用水水碘含量分布情况,更好指导碘缺乏病防治工作,我市开展了居民
Iodine is an essential trace element for the human body and is an important element for the synthesis of thyroxine. The main sources of iodine in human body are water and food. In the absence of external iodine, iodine content is an important index to measure iodine intake of local residents ~ ([1]). With the rapid economic development in our city and the implementation of rural water and lavatories, the change of drinking water source and the change of time will inevitably lead to the change of iodine content in drinking water ([2]). Neijiang was once an area of iodine deficiency in Sichuan Province. In 2010, iodine deficiency was eliminated. In order to fully understand the distribution of iodine in drinking water in our city and better guide the prevention and treatment of iodine deficiency disorders,
