Abstract

Over the past twenty years progress in geochemical research has led to a better understanding of the distribution of elements in rocks and soils and of the processes that control their redistribution in the surface environment. However, little systematic information is available on the geographic distribution of elements in soils, plants and waters, such as would be necessary for spatial relationships between geochemistry and health to be established. In particular, data on levels of trace element abundances in these media are considered to be essential.KeywordsIodine DeficiencyEssential Trace ElementEnvironmental GeochemistryEndemic GoitreTrace Element AbundanceThese keywords were added by machine and not by the authors.
