摘要
目的:掌握焦作市解放区小学生食用碘盐情况,为消除碘缺乏病提供科学依据。方法:焦作市解放区每年按东、南、西、北、中划分5个抽样片区,在每个片区各随机抽取个1所学校,每所学校抽取30名8～10岁学生,样品采集家中食用盐。采用直接滴定法(GB/T13025.7-1999)测定盐中碘含量。结果:2010年～2012年检测855份,合格碘盐825份,不合格碘盐27份,3份非碘盐,碘盐合格率96.83%,碘盐覆盖率99.65%,碘盐食用率96.49%。结论:碘盐合格率、碘盐覆盖率、合格碘盐食用率>90%,达到碘缺乏病持续消除状态。
Objective ：To grasp the situation of pupils edible iodate in Jiefang district,Jiao- zuu city, and to provide scientific basis for e- liminatiulg IDD. Methods ： five sampling area have been divided according to the east, south, west, north and centre,each random l school, every school extraction 30 eight to ten years old students. The experimental pe- riod is 2010 -2012 year in Jiefang district, Jiaozuo city, sample collection from home edible salt. Direct titration method （GB/ T13025.7 -1999）has been used to deter- minates the iodine in salt. Resuhs：855 cop- ies have been detected during 2010-2012, the eligible iodate 825 copies,unqualified i- odate amt 3 non iodate,iodate qualified rate is 96. 83%, iodate coverage rate is 99. 65% ,iodate edible rate was 96.49%. Con- clusious： iodate pass percent, iodate cover- age,qualified iodate edible rate are all over 90%,and achieve continuous idd elimina- tion state.
