对新修订的《水源性高碘地区和高碘病区的划定》标准的解读

An interpretation of the newly revised standard on ＂Definition and Demarcation of Water-borne Iodine- excess Areas and Iodine-excess Endemic areas＂

为了解决《水源性高碘地区和地方性高碘甲状腺肿病区的划定》（GB／T19380—2003）在指导实际工作时遇到的困难和存在的局限之处，对原标准从名称、规范性引用文件、高碘地区／病区的定义及其划分的技术指标、附录的抽样方法5个方面进行了修订，形成了《水源性高碘地区和高碘病区的划定》标准，通过对《水源性高碘地区和高碘病区的划定》标准解读，旨在为水源性高碘防治提供参考。

In order to solve some limitations and difficulties in guiding the practical work of determination and classification of the areas of high water iodine and the endemic areas of iodine excess goiter （GB/T 19380-2003）, we carried out the revision on the original standard from 5 aspects such as the name, normative reference file, the definition and the technical indicators of classification of high iodine areas and the endemic areas of iodine excess goiter, such as sampling method in appendix and so on, and worked out the standard of definition and demarcation of water-borne iodine-excess areas and iodine-excess endemic areas. Enforcement of the new standard will bring important social benefits.
