Objective:
To study the effect of high iodine concentration in drinking water on thyroid function of elementary school student in Tianjin.
Methods:
According to the water monitoring results and determination standard of iodine concentration excess area, urine iodine level and thyroid condition of elementary students were tested in the area with high and low water iodine concentration. Meanwhile the condition of iodized salt intaked students' family was inspected.
Results:
The content of urine iodine and goiter rate of students in the area with high water iodine concentration were significantly higher than those with low water iodine concentration. But the iodine concentration of edible salt in students' family in the area with high water iodine concentration were significantly lower than those of students' family with low water iodine concentration.
Conclusion:
High water iodine concentration could impact thyroid function of elementary students in Tianjin.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
