目的了解芗城区居民食用盐的碘含量及分布。方法每年4月在芗城区的东西南北中方向各随机抽取居民户家中食用盐60份,据GB/T 13025.7-2012的直接滴定法检测。结果 2012—2013年共采居民户家中食用碘盐600份,碘盐覆盖率99.7%,碘盐合格率98.8%,合格碘盐食用率98.5%,不合格碘盐率1.2%,非碘盐率0.3%;2013年合格碘盐食用率高于2012年,碘盐合格率和不合格碘盐率均低于2012年;2012年盐碘均数27.09mg/kg,检出范围0~61.8mg/kg,其中18~33mg/kg占92.3%,<5mg/kg占0.7%,5~18mg/kg占2.3%,>33mg/kg占5.3%;2013年盐碘均数26.29mg/kg,检出范围16.50~40.10mg/kg,其中18~33mg/kg占99.3%,<18mg/kg占0.3%,>33mg/kg占0.33%;2012年18~33mg/kg构成比低于2013年。结论芗城区碘缺乏病得到控制,达到消除碘缺乏病的目标。2013年碘盐检测结果已接近国标,但监测仍需长期坚持。
Objective To understand the iodine content and distribution of edible salt in Xiangcheng District. Methods In April of each year, 60 samples of household salt from households were randomly collected in the east, west, south and north directions of Xiangcheng District, and detected according to the direct titration method of GB / T 13025.7-2012. Results In 2012-2013, there were 600 iodized salt, iodized salt coverage rate of 99.7%, iodized salt rate of 98.8%, qualified iodized salt rate of 98.5%, unqualified iodized salt rate of 1.2%, non-iodized salt rate 0.3%. In 2013, the qualified iodized salt consumption rate was higher than that in 2012, the qualified rate of iodized salt and the unqualified iodized salt rate were lower than that of 2012; the average iodine salt number was 27.09 mg / kg in 2012, with the detection range of 0 to 61.8 mg / kg, accounting for 92.3% at 18-33mg / kg, 0.7% at <5mg / kg, 2.3% at 5-18mg / kg and 5.3% at> 33mg / kg; The range of 16.50 ~ 40.10mg / kg, of which 18 ~ 33mg / kg accounted for 99.3%, <18mg / kg accounted for 0.3%, 33mg / kg accounted for 0.33%; 2012 18 ~ 33mg / kg constituent ratio lower than 2013. Conclusion Tancheng iodine deficiency disorders are controlled to achieve the goal of eliminating iodine deficiency disorders. 2013 iodized salt test results are close to the national standard, but the monitoring still need long-term adherence.
