Chemical hazards in drinking-water - iodine
Iodine is considered in the WHO Guidelines for Drinking-water Quality. You can link from here to:
The Guidelines for drinking water quality also consider for individual chemicals:
-
Aspects of analytical achievability [Section 8.3, pp. 157-166]

Rolling revision of the WHO Guidelines for Drinking-water Quality
Iodine is included in the plan of work of the rolling revision of the WHO Guidelines for Drinking-water Quality.
Background
The Guidelines for Drinking-water Quality Final Task Force meeting (Geneva, 2003) recommended that iodine be referred to JECFA because of toxicological concerns regarding the use of iodine as a disinfectant in emergency situations and that a background document on iodine be prepared as part of the rolling revision. A CICAD on iodine, based on an ATSDR report, is in the drafting process.
Expected end-product(s)
Revised background document (taking essentiality aspects into consideration as well as updated toxicological information) for second addendum to Third Edition or for Fourth Edition
Progress to date
The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2004) agreed on a plan of work, which was revised by the Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005). The first step is to review the CICAD draft for the next meeting.
