4 Δεκ 1996 · Based on this information, this document summarizes current WHO, UNICEF and ICCIDD recommendations concerning iodine levels in salt, risk of associated iodine-induced hyperthyroidism, and requirements for monitoring both iodine status and adequacy of iodine levels in salt.
Exposure to iodine may occur through drinking-water, pharmaceuticals, and food. At a concentration of 4 µg/litre in drinking-water, adult human daily intake will be 8 µg of iodine, on the assumption that 2 litres of drinking-water are consumed per day. KINETICS AND METABOLISM IN LABORATORY ANIMALS AND HUMANS
If the water iodine of the village fit the pre-set level, the drinking water of the children's and pregnant women's households was sampled to test the actual water iodine level. The table salt of the children's and pregnant women's households was sampled for testing through a semi-quantitative method (<5 mg/kg was defined non-iodised salt).
For women living in countries with weak, sporadic, or uneven iodized salt distribution, the WHO recommends iodine supplementation for all women of childbearing age to achieve a total iodine intake of 150 mcg/day.
Determine the performance of a laboratory spectrophotometric method and three single-wavelength spectrophotometric devices for quantifying iodine in salt against the standard iodometric titration method. Compare the analytical accuracy and precision, simplicity of use, and cost.
9 Σεπ 2013 · The two main methods used to determine iodine levels in urine and milk are as follows: The instrumental method and the colorimetric methods in association with Sandell and Kolthof reaction.
1 Φεβ 2010 · The concentration of iodine in urine and salt provide data on the key indicators used in the assessment of iodine nutritional status in populations. Iodine is determined in salt samples collected at the production sites, retail and household levels and in urine samples collected from children, women and infants.
