Iodide concentrations in Saudi waters: a cause for concern

ABSTRACT

Samples of tap water and drinking mineral water from different regions of Saudi Arabia were analyzed for iodide content. Low iodide concentrations were found in all samples. This finding may reflect an overall low iodide content in the soil and consequently also in locally grown food, which could predispose to endemic goiter. In the absence of data on the prevalence of endemic goiter, we recommend the routine use of iodized salt in Saudi Arabia
