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.
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.
1 Ιουν 2017 · Iodine in salt is determined quantitatively by the titration method, colorimetrically by the WYD iodine checker or by a technologically advanced potentiometric method.
measuring iodine content in household salt have been an important monitoring tool for assessing the performance of salt iodization programmes. While iodine in the diet was previously assumed to come predominantly from household iodized salt, recent evidence suggests that an increasing amount of iodized salt is consumed through processed
20 Μαΐ 2016 · The median and interquartile range iodine concentration in salt was 2.9 mg/kg (IQR: 2.4-3.7). The results show that only 25 % of households use iodized salt. The recommended iodine concentration in salt of 15–40 mg/kg was met only in 4.5 % of salt samples. The bulk salt is used by 8 % of households.
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.
monitoring salt iodine content, whether at the factory, importation site, or household level. Also included are recommendations on methods for monitoring iodine status and determining urinary iodine; and on the characteristics and criteria for selection of clinical and biochemical indicators, age and physiological groups, and survey sample size.
