Document Summary
Interdisciplinary science dealing with the relationship between geological factors and health problems in humans, animals and plants. Looks at health problems caused or exacerbated by geologic materials such as trace elements, rocks, minerals, water, petroleum and geologic processes (eg. volcanic eruptions, earthquakes and dust) Natural occurrence of elements in the geologic environment: eg. ingestion of food grown in soils with element deficiencies or toxicities. Elemental occurrence relative to natural hazards: earthquakes, volcanic eruptions, flooding and landslides. Identify geochemical anomalies in soils, sediments and water that can/could have an adverse impact on the health of humans and animals. Exposure to toxic levels of trace (non-)essential elements. Naturally occurring toxic organic and inorganic compounds in drinking water (esp. arsenic) Element pathways to the food chain are governed by geology geological knowledge is needed to understand human health issues. Inhalation: primary pathway for airborne particles, natural and anthropogenic sources.
