Iodine was discovered as a new element two centuries ago. It is essential to human health, yet a substantial proportion of the world's population are at risk from a lack of dietary iodine. Natural processes within the oceans are responsible for the majority of atmospheric iodine. In the lower atmosphere, iodine undergoes a complex array of photochemical reactions that lead to ozone destruction and, in some cases, new particle formation, before being scavenged by aerosol. The nature and mechanisms for oceanic iodine emissions are still uncertain.
