Medical geology：new relevance in the earth sciences

The interdisciplinary fieldresponds to the need to betterof “Medical Geology“ understand the relationships between human health and our surrounding environment. The influence of earth resources, natural environmental factors and land-use on human health has long been recognized, dating back to ancient Rome and Peru‘s Inca civilization.
