目的了解郧县居民食用碘盐质量状况,为制订防治策略提供科学依据。方法根据《湖北省碘盐监测实施细则》进行监测,2007-2011年共抽取全县居民户1 440份盐样,采用《GB/T13025.7-1999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 2007-2011年共检测郧县居民户食用碘盐居民户盐样1 440份,其中非碘盐20份,不合格碘盐52份,合格碘盐1 368份,非碘率为1.39%,碘盐覆盖率为98.61%,碘盐合格率为96.34%,合格碘盐食用率为95.0%。结论我县居民食用碘盐的合格率逐年增加,非碘盐食用率逐年下降,2010-2011年碘盐覆盖率达100.0%,今后还需加强监督监测,强化健康教育、健康促进,以确保各项措施得到长期落实。
Objective To understand the quality of iodized salt consumed by residents in Yun County and provide a scientific basis for formulating prevention and control strategies. Methods According to the “Implementation Rules of Iodized Salt Surveillance in Hubei Province”, a total of 1 440 samples of salt were collected from 2007 to 2011 in the county. The “Determination of iodide in GB / T13025.7-1999 Common Test Methods for Salt Industry” Direct titration for quantitative detection. Results A total of 1 440 samples of salt samples were collected from households living in Yunxian County from 2007 to 2011. Among them, 20 were non-iodized salt, 52 were unqualified iodized salt, 1 368 were qualified iodized salt, and non-iodine rate was 1.39% The coverage of iodized salt was 98.61%, the qualified rate of iodized salt was 96.34%, and the qualified iodized salt was 95.0%. Conclusion The passing rate of iodized salt in our county is increasing year by year. The non-iodized salt consumption rate declines year by year. The coverage rate of iodized salt in 2010-2011 is 100.0%. In the future, supervision and monitoring should be strengthened to strengthen health education and health promotion so as to ensure that Long-term implementation of measures.
