为消除碘缺乏病,全面、准确掌握津南区农村居民食用盐状况,抽取了津南区5个镇,按照《全国碘盐监测方案》,2006—2008年各镇选取4个村,每村随机抽取8户居民;2009—2010年各镇选取4个村,每村随机抽取15户居民,共检测居民食用盐1 080份。按照GB/T 13025.7—1999《制盐工业通用试验方法碘离子的测定》2.1直接滴定法检测食盐碘的含量。根据GB5461—2000《食用盐》进行评价。表1可见,农村居民碘盐覆盖率、碘盐合格率、合格碘盐食用率均为2008年最低,2009年最高。而2009年和2010年检测的农村居民碘盐覆盖率、碘盐合格率、合格碘盐食用率均在95%以上。
In order to eliminate iodine deficiency disorders, we comprehensively and accurately grasped the status of salt consumption of rural residents in Jinnan District. Five towns in Jinnan District were extracted. According to the National Iodized Salt Monitoring Program, four villages were selected from each town in 2006-2008. 8 households; from 2009 to 2010, 4 townships were selected in each town, and 15 households were randomly selected from each village. A total of 1 080 household salt samples were tested. According to GB / T 13025.7-1999 “Salt Industry General Test Method for Determination of Iodine” 2.1 direct titration salt iodine content. According to GB5461-2000 “edible salt” for evaluation. Table 1 shows that rural residents iodized salt coverage, qualified rate of iodized salt, qualified iodized salt consumption rates were the lowest in 2008, the highest in 2009. The coverage rates of iodized salt, iodized salt and iodized salt in rural residents tested in 2009 and 2010 were above 95%.
