- An accurate and precise method of iodine determination in drinking water using ICP-MS was developed. The method LOQ (considering the 2-fold dilution of the sample and possible memory effect) was <0.1 µg I L-1. Use of an alkaline matrix (2% NH4OH + 0.1% EDTA) for sample dilution and calibration standard preparation prevented carbonate precipitation and, as a result, nebulizer clogging. A sampling of the bottled mineral water brands available in the Israeli market demonstrated relatively low average iodine content (7.68±2.41 µg L-1 ). The measurement of total iodine concentration in tap water samples across Israel revealed a decrease in the present-day iodine status compared with the data from literature sources. We observed 0.3 – 12.3 µg I L-1 (median values); however, approximately 5 – 50 µg I L-1 was recommended by other researchers as a risk-reducing concentration.
