A field test for detecting iodine-enriched salt.
One of the most effective and well-established methods for the prevention of endemic goitre is the enrichment of table salt with appropriate amounts of iodine. A simple field test has been developed by which anyone, without special chemical training, can verify whether a sample of table salt has been enriched with iodine as required by local health regulations. Since all the equipment needed can conveniently be assembled as a small portable kit, the proposed method, which is highly sensitive, is appropriate for health workers in areas prone to endemic goitre.
