The Drinking Water Sanitation Standard (GB 5749-2022) has been officially promulgated and implemented, with the iodide listed as a new reference indicator for water quality. This study interprets the distribution of iodine in environmental media, the impact of water iodine on health, the significance of establishing iodide standard limits, and the use of iodide standard limits, in order to provide a scientific basis for the application of iodide standard limits in this revised standard.
《生活饮用水卫生标准（GB 5749-2022）》已正式颁布并实施，其中碘化物指标作为新增指标被列为标准的水质参考性指标。本研究从碘在环境介质中的分布情况、水碘对人体健康的影响、设立碘化物标准限值的意义以及碘化物标准限值的使用等方面进行了解读，以期为新版标准中碘化物标准限值的应用提供科学依据。.
