Iodine: Iodides
built 635 days ago
Iodine can be found naturally in air, water and soil. The most important sources of natural iodine are the oceans. About 400.000 tonnes of iodine escape from the oceans every year as iodide in sea spray or as iodide, hydrichloric acid and methyl iodide, produced by marine organisms. Much of it is deposited on land where it may become part of the biocycle.

Iodine is used as a disinfectant, or at least used to be. This vial contains 10 grams of resublimated iodine plus 3.5 grams of potassium iodide, and the label says it's from the "main veterinary place" in Berlin. It is said to be antique.

Iodine supplements come in various forms including ammonium iodide, calcium iodide, potassium iodide and kelp. People who live in low soil iodine areas who restrict the salt in their diet and do not eat fish may benefit from iodine supplements.

Iodine is found in the earth's crust in sparse amounts and is in the form of iodide. Since iodide is soluble, soils will be lowest in iodine in areas where there is much rainfall or where glaciers have melted and leached the iodine out of the soil.
