Iodine was discovered by Bernard Courtois in 1811. He was born to a manufacturer of saltpeter (a vital part of gunpowder). At the time of the Napoleonic Wars, France was at war and saltpeter was in great demand. Saltpeter produced from French niter beds required sodium carbonate, which could be isolated from seaweed washed up on the coasts of Normandy and Brittany. To isolate the sodium carbonate, seaweed was burned and the ash then washed with water. The remaining waste was destroyed by adding sulfuric acid.

Iodine is primarily retrieved from underground brines (water with many dissolved salts and ions) that are associated with natural gas and oil deposits. It is ... retrieved as a by-product with nitrate deposits in caliche deposits. Chile’s production of iodine is from this source. Seawater contains 0.05 ppm (parts per million) iodine which means that there are approximately 76 billion pounds of iodine in the world’s oceans. Iodine was first discovered in seaweed. Dried seaweeds, particularly those of the Liminaria family, contain as much as 0.45% iodine.

Iodine deficiency in children and adolescents is often associated with goiter. The incidence of goiter peaks in adolescence and is more common in girls. School children in iodine-deficient areas show poorer school performance, lower IQs, and a higher incidence of learning disabilities than matched groups from iodine-sufficient areas. A meta-analysis of 18 studies concluded that iodine deficiency alone lowered mean IQ scores in children by 13.5 points (11, 12).

Iodine is found mainly in sodium and potassium compounds. Thus, Iodine is required in humans. You can find more Iodine in old salt wells and salt brines. Its natural form is a blue-black solid.

Iodine is absorbed intestinally from dietary sources or dermally from topical iodine applications or from iodine vapors produced as byproducts of industrial activity. Iodine vapor is ... emitted from cleansing agents used commercially in sterilization processes and from fossil fuel combustion such as occurs in automobile engines. Currently, the most common source of exposure to iodine is from automobile exhaust. In the 1970's, the amount of iodine measured in the environment reached levels that were a cause for concern prompting the dairy industry to discontinue use of iodine-containing agents in sterilization of milking equipment to reduce the iodine content of milk.

Iodine is commonly used in topical disinfectant preparations for cleaning wounds, sterilizing skin before surgical/invasive procedures, or sterilizing catheter entry sites. Betadine solution, for example, contains povidone-iodine. Other topical disinfectants include alcohol and antibiotics, and iodine is sometimes used in combination with these. Commercially prepared iodine products are recommended in order to assure appropriate concentrations.
