对 176 2份碘盐进行了快速定量检测筛查 ,并与实验室方法对照 ,检测结果为 :①销售点碘盐含碘量M为 4 0 5× 10 - 6 ,合格率为 97 4 % ;非碘盐及碘盐含碘量M <2 0× 10 - 6 ,均为“0” ;>6 0× 10 - 6 为 2 6 %。②居民食盐含碘量M为 4 0 0× 10 - 6 ,合格率为 95% ;<2 0× 10 - 6 为2 5% ,>6 0× 10 - 6 为 0 7% ;非碘盐为 1 8%。本法与实验室定量方法比较 ,P >0 0 5,无显著差异。判定本法是准确的。
A total of 176 2 iodized salt samples were screened by rapid quantification and compared with laboratory methods. The test results were as follows: 1) The iodine content of iodized salt at the point of sale was 4 0 5 × 10 - 6 with a pass rate of 97 4% The iodine content of non-iodized salt and iodized salt was M <2 0 × 10 -6, both “0”;> 6 0 × 10 -6 was 26%. (2) The iodine content of residents’ salt was 4 0 0 × 10 - 6, the pass rate was 95%; that of 2 0 × 10 - 6 was 25%, that of 0 6 0 × 10 - 6 was 0 7% 18%. The method and laboratory quantitative methods, P> 0 0 5, no significant difference. Judge this law is accurate.
