Models for the distribution of estimated daily iodine intakes according to likely, best- and worst-case assumptions of water iodine content. The distribution of the study population’s iodine intake (µg/d) from the sIFFQ (n 74) estimated assuming three different iodine concentrations for tap water: (a) likely, 27 µg/l; (b) worst-case scenario using only iodine content in SWRO desalinated water, 1 µg/l; (c) best-case scenario based on the highest local iodine content measured in well water, 170 µg/l. ——— indicates Weibull fit; – – – – – indicates RDA reference line (150 μg/d) (sIFFQ, semi-quantitative iodine FFQ; SWRO, seawater reverse osmosis)
