ABSTRACT

Objective:

To investigate the iodine content distribution of drinking water in Jiangsu Province.

Methods:

In 2017, the iodine content in drinking water of residents in townships (streets, hereinafter referred to as townships) of Jiangsu Province was investigated. Administrative villages (neighborhood committees, hereinafter referred to as administrative villages) of Jiangsu Province were selected as units for the investigation of townships with the median water iodine greater than 10 μg/L. Delimitation criteria the median iodine content of water < 40 μg/L was iodine deficiency area, 40-100 μg/L was suitable iodine area, and > 100 μg/L was high iodine area.

Results:

A total of 1 285 townships were surveyed in 101 counties (cities, districts) in 13 cities, and the median water iodine in townships was 7.28 μg/L. Among them, there were 875 townships with median water iodine < 10 μg/L, accounting for 68.09%; 315 townships 10-< 40 μg/L, accounting for 24.51%; 56 townships 40-100 μg/L, accounting for 4.36%; 39 townships > 100 μg/L, accounting for 3.04%. The water iodine survey at the administrative village level was conducted in 5 864 administrative villages in 410 townships in 6 cities. Among them, 769 administrative villages with median water iodine < 10 μg/L, accounting for 13.11%; 3 558 administrative villages 10 - < 40 μg/L, accounting for 60.68%; 613 administrative villages 40 - 100 μg/L, accounting for 10.45%; and 924 administrative villages > 100 μg/L, accounting for 15.76%.

Conclusion:

According to the water iodine, there are iodine deficiency, suitable iodine and high iodine areas in Jiangsu Province, mainly in iodine deficiency areas.
