| 目的 了解全国生产和居民层次碘盐合格及食用情况.方法 监测方法参见卫生部2004年颁布的"全国碘盐监测方案"(修订).碘盐检测采用GB/T 13025.7-1999中直接滴定法;川盐或特殊盐种检测采用仲裁法定量测定.合格碘盐判定标准:35 mg/kg±15 mg /kg(20～50 mg/kg);非碘盐判定标准:＜5 mg/kg.结果 全国生产层次碘盐的批质量合格率为98.36%;各省(自治区、直辖市)的批质量合格率均＞90%.全国居民层次的碘盐覆盖率为96.87%,合格碘盐食用率为93.75%.西藏、海南、新疆、广东省的居民碘盐覆盖率＜90%.西藏、海南、新疆、广东、青海省的居民合格碘盐食用率＜90%.2006年有80个监测盲区县,有185个县非碘盐率＞10%.在县级居民合格碘盐食用率指标上,全国距离"95%的县实现消除碘缺乏病标准"的目标还相差约10个百分点.结论 从全国水平看,生产层次碘盐合格率和居民层次碘盐覆盖率都保持在一个较高的水平;但在县级水平,有75个县碘盐覆盖率＜70%. |

| Objective To understand the national situation of quality and consumption of iodized salt at production and household levels. Methods Detailed surveillance method could be found in‘national iodized salt surveillance scheme', issued by MOH in 2004. The iodine concentrations in salt ( except some special kinds of salt ) were detected by direct titration with national standard of GB/T 13025. 7-1999, in which the iodine content in qualified iodized salt was set as between 20 and 50 mg/kg and that in non-iodized salt was set as below 5 mg/kg Results At production level, the national lot qualified rate was 98. 36 % and all the provincial lot qualified rate of production level was over 90 %.At household level, the national iodized salt coverage rate of household was 96. 87 % and the national qualified iodized salt coverage rate was 93. 75 %.4 provinces (Tibet,Hainan,Xinjiang and Guangdong) had an iodized salt coverage rate lower than 90 %，Further,the qualified iodized salt coverage rate of 5 provinces (Tibet,Hainan,Xinjiang,
Guangdong and Qinghai) was below 9096.In 2006,80 counties did not conduct the iodized salt surveillance and non-iodized salt coverage rate of 185 counties was higher than 10 %, In the respect of the qualified iodized salt coverage rate at household level, there were about 10 percent lagging behind the national goal that 95 0,6 of all the counties in China should achieve virtual elimination of iodine deficiency disorder before 2010.Conclusion At national level, the lot qualified rate at production level and the iodized salt coverage rate at household level maintained comparatively well. However, at county level, there were 75 counties
whose iodized salt coverage rate was below 70%. |
