Iodine as a trace micronutrient has important role in body physiology and its sufficient intake is essential for synthesize and secrete adequate amounts of thyroid gland hormones which influenced all periods of human life including fetal, childhood and adolescence. The aim of this study was to evaluate iodine concentration in marketed edible salt samples in Lorestan Province, comparing with existing standards and offering solutions necessary to fix the probably problems. Two hundred and forty samples of 20 brands of marketed edible salt were purchased randomly of eight cities in Lorestan Province during April 2014 to March 2015. Iodine concentration was measured by titration method. Results showed that iodine concentration in 64.59% of salt samples was in acceptable limits according national standard of Iran during this study. A significant number of nonstandard samples showed violation of salt factories of regulations and their noncompliance to mandatory standards. Due to importance of iodine in human health and valuable role in the vital functions of the body at different periods of human life and to avoid violations of iodized salts manufacturers, regular control of marketed salts and enforcement of laws and regulations are recommended.aflatoxin production in treated nuts.
