- Medical Geology: a globally emerging discipline J. E. Bunnell R. B. Finkelman J. A. Centeno O. Selinus Ciencias de la Tierra Human health Public health Medical geology Environmental health Medical Geology, the study of the impacts of geologic materials and processes on animal and human health, is adynamic emerging discipline bringing together the geoscience, biomedical, and public health communities to solvea wide range of environmental health problems. Among the Medical Geology described in this review are examplesof both deficiency and toxicity of trace element exposure. Goiter is a widespread and potentially serioushealth problem caused by deficiency of iodine. In many locations the deficiency is attributable to low concentrationsof iodine in the bedrock. Similarly, deficiency of selenium in the soil has been cited as the principal cause ofjuvenile cardiomyopathy and muscular abnormalities. Overexposure to arsenic is one of the most widespreadMedical Geology problems affecting more than one hundred million people in Bangladesh, India, China, Europe,Africa and North and South America. The arsenic exposure is primarily due to naturally high levels in groundwaterbut combustion of mineralized coal has also caused arsenic poisoning. Dental and skeletal fluorosis also impactsthe health of millions of people around the world and, like arsenic, is due to naturally high concentrations in drinkingwater and, to a lesser extent, coal combustion. Other Medical Geology issues described include geophagia, thedeliberate ingestion of soil, exposure to radon, and ingestion of high concentrations of organic compounds indrinking water. Geoscience and biomedical/public health researchers are teaming to help mitigate these healthproblems as well as various non-traditional issues for geoscientists such as vector-borne diseases 2007 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50550305 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.3 Vol.5
