Atmospheric Chemistry of Iodine

Summary
Soil can affect human health in several ways leading either to specific diseases or to more general ill health. Some illnesses are caused by people's eating soil (geophagia), or by their inhaling it which can lead to malignancy if the soil contains asbestiform minerals; pathogens in the soil can lead to tetanus and infestations of hookworm, and particles may enter the body through abrasions and cause a form of elephantiasis. Radon from the soil is implicated in some cancers, and poorly drained soil has been linked recently with infant mortality. Most examples of ill health associated with the soil are caused by concentrations of elements in food or water that are either deficient or toxic. These elements include aluminium, arsenic, cadmium, copper, fluorine, iodine, lead, selenium, thallium and zinc. Their concentrations might reflect the natural condition of the soil, or the effects of people's actions, such as pollution. In isolated subsistence communities that grow their own food, distinct relations between elements and the aetiology of diseases can be identified. Examples include Keshan disease caused by selenium deficiency, and itai-itai disease caused by excess cadmium. Some of the relations between soil and health are uncertain and the causes putative, and they require further research to validate them. They include the association of heart disease with poor acid soil, as in the glaciated regions of northern Europe and the coastal plain of the eastern United States of America. Even for well-defined relations it is evident that many are more complex than was originally thought, however, and greater understanding will require multidisciplinary investigation.

Soil and human health: a review

Iodine has long been recognised as an important element environmentally. Despite this there are many gaps in our knowledge of its geochemistry and even where information is available much of this is based on old data which, in the light of recent data, are suspect. Iodine forms few independent minerals and is unlikely to enter most rock-forming minerals. In igneous rocks its concentration is fairly uniform and averages 0.24 mg/kg. Sedimentary rocks tend to have higher concentrations with average iodine contents of:-recent sediments 5–200 mg/kg, carbonates 2.7 mg/kg, shales 2.3 mg/kg and sandstones 0.8 mg/kg. Organic-rich sediments are particularly enriched in iodine. Soils, generally, are much richer in iodine than the parent rocks with the actual level being decided mainly by soil type and locality. Little soil iodine is water-soluble and much iodine is thought to be associated with organic matter, clays and aluminium and iron oxides. Most iodine in soils is derived from the atmosphere where, in turn, it has been derived from the oceans. Seawater has a mean iodine content of 58 μg/L, while non-saline surface waters have lower and very variable levels. Subsurface brines and mineral waters are generally strongly enriched in iodine. Marine plants are frequently enriched in iodine while terrestrial plants have generally low contents. Iodine is essential for all mammals. Consideration of the geochemical cycle of iodine reveals that its transfer from the oceans to the atmosphere is probably the most important process in its geochemistry.
