In city, the median of salt iodine was 33.4~ 35.6 mg/kg, and the rate of qualified iodinated salt was 87%~96% in 4 groups (exclude infant's group), the rate of qualified iodinated salt was below 90% in breast-feed woman group.
Results The median of local water iodine content was 3.05 μg/L and the average salt iodine concentration was (36.4± 5.4)mg/kg while 98.8% of the household consumed sufficient iodized-salt.
Results The results showed that the rates of iodized salt at household levels were 49.2% in 1995,84.0% in 1997,87.1% in 1999 and 93.0% in 2002,with the median of iodized salt content was 0,23.3,28.6 and 29.0(mg/kg),correspondingly.
Results The median of iodized salt in household consuming was 34.9 mg/kg, the rate of qualified iodized salt was 87.2%, variation coefficient of iodized salt was 26.8%, the proportion of high concentrate iodine salt (> 60 mg/kg or >50 mg/kg) was significantly lower than the third surveillance.
Based on the comparison between sodium hypochlorite oxidation method of GB/T13025.7-1999and saturated bromine water oxidation method of GB/T13025.7-91in iodine content testing of iodized salt,saturated bromine water oxidation method of GB/T13025.7-91is recommended as the arbitration of testing io-dine content in iodized salt.
Results Iodine concentration median of iodized salt (235 samples) was 32.8 mg/kg ( range 0.1 -83.0 mg/kg,90% more than 15mg/kg) , 29.6 mg/kg in urban district and 33.2 mg/kg in rural area.
Conclusion:Iodine nutrition status of children differed not only from individual to individual but also from area to area, and it could be significantly influenced by salt iodine content.
Results The multilevel model of geographic distribution of children's urine iodine in three years showed that the differences of children's urine iodine were significant in various regional and individual levels. Besides,salt iodine content had an obvious effect on the urine iodine level.
Results The median of iodized salt in household consuming was 34.9 mg/kg, the rate of qualified iodized salt was 87.2%, variation coefficient of iodized salt was 26.8%, the proportion of high concentrate iodine salt (> 60 mg/kg or >50 mg/kg) was significantly lower than the third surveillance.
-Result- Thyroid gland swell rate of children is 3.34%,the median of urine iodine is 124.3μg/L, there is no specimen which median of urine iodine is lower 50μg/L, salt iodine is 25.79±10.23mg/Kg, the percentage of household consuming effective iodine salt is 94.0%.
[Results]There are 256 residents in 8 communities(include individual commerce),and by detecting 256 edible salt samples,we find that the mean of Iodine salt is(29.98±9.14) mg/kg,the use of Iodine salt is 96.48% and eligible of Iodine salt is 91.40%.
Objective Assessing the 30 county labs on quality control in order to do well to the iodine salt monitoring network of all over country and insure accuracy of salt iodine measure.
It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not.
The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary.
Iodine concentration in canteen meals prepared with or without iodized salt
In each of two university canteens differing in the use (canteen A) or non-use (canteen B) of iodized salt for food preparation, 15 mostly equal lunch meals were collected for iodide and NaCl analysis.
Consequently, the use of iodized salt in central catering seems to play a more important role in a sufficient I intake than assumed so far.
To investigate iodine and selenium levels of neonates in the Shaanxi sub-clinical cretinism region of China after supplement of iodine salt for nearly twenty years.
The inhibiting action of alkyltriphenylphosphonium iodine salt ((C8H17)Ph3P+,I-) towards the corrosion behaviour of nickel in 1 M H2SO4 solution has been studied.
