2010—2012年天津市塘沽区碘盐监测结果

Monitoring results of iodized salt in Tanggu District of Tianjin City from 2010-2012

目的为了解塘沽居民户食用碘盐质量状况,动态评价人群碘营养状况,为制定防治策略提供科学依据。方法根据《天津市碘盐监测实施方案》进行居民户碘盐监测,2010—2012年共选点采取居民户876份盐样,采用GB/T 13025.7-1999《制盐工业通用试验方法碘离子的测定》直接滴定法进行定量检测。结果 2010—2012年共检测塘沽居民户食用碘盐样品876份,其中非碘盐35份,不合格碘盐21份,合格碘盐820份,碘盐覆盖率为96.00%,碘盐合格率为97.50%,合格碘盐食用率为93.61%。结论塘沽居民合格碘盐食用率水平较高,现阶段居民合格碘盐食用率指标达到国家消除碘缺乏病判定标准,但仍需加强监督监测,强化健康教育,以确保各项措施得到长期落实。

[ Objective ] To understand the quality of iodized salt of households in Tanggu District, dynamically evaluate the iodine nutritional status of population, and provide scientific evidence for developing the control strategies. [ Methods ] Iodized salt was monitored according to the Iodized salt monitoring ordinance in Tianjin, and a total of 876 iodized salt samples were collected from households from 2010-2012. The quantitative detection was conducted by direct titration method from the General test method in salt industry-Determination of iodide ion （GB/T 13025.7-1999）. [ Results] A total of 876 iodized salt samples of households in Tanggu District were tested from 2010-2012. There were 35 samples of non-iodized salt, 21 samples of unqualified iodized salt, and 820 samples of qualified iodized salt. The coverage rate of iodized salt was 96.00%, the qualified rate of iodized salt was 97.50%, and the consumption rate of qualified iodized salt was 93.61%. [ Conclusion ] The consumption rate of qualified iodized salt among resi-dents in Tanggu District is high, which has reached the national standard of eliminating iodine deficiency disorders at present. How-ever, it is necessary to strengthen the supervision and monitoring, improve health education, to ensure the long-term implementation of all measures.
