Heavy Metals Contamination of Table Salt Consumed in Iran
Authors
Abstract:
Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has been banned by Iranian health authorities. In this study, heavy metal contamination of table salt consumed in Iran has been investigated. One hundred samples of rock and refined table salts were analyzed using atomic absorption spectrophotometeric methods for the presence of toxic heavy metals. The mean concentration of tested tracer metals including Cd, Pb, Hg and As was 0.024, 0.438, 0.021 and 0.094 µg/g, respectively. The concentrations of tested heavy metals were well below the maximum levels set by Codex. However, no statistically significant difference was found between contamination of rock salt and refined salt to heavy metals.

full textEvaluation of Heavy Metals Contamination of Unrefined and Refined Table Salt
Edible salt is the most used food additive worldwide. Therefore, any contamination of table salt could be considered as a health hazard to the consumers. The present study goal is to determine the levels of heavy metals in the table salt refined and unrefined. Eighty one refined salt samples and 81 unrefined salt samples were purchased from retail market in the province of Hamadan, Iran. The le...
