Medical geology is the study of the relationships between geoenvironmental factors and the health of plants, animals and humans. BGS has extensive expertise researching medical geology issues in the UK and internationally and the association between environmental geochemistry and health in particular.

Geochemistry and health issues can arise as a consequence of a lack of essential nutrients in geological materials such as soil and water, resulting in inadequate uptake into plants, animals and humans via the food chain. The ability of the natural environment to provide adequate essential nutrients is of prime importance to agricultural management. Issues can also be caused by exposure to high concentrations of potentially harmful chemical substances in the environment (air; dust; soil; water; foodstuffs). Elevated concentrations of potentially harmful substances can occur naturally, as a consequence of geological and other environmental processes, or as a result of pollution by human activities.

Medical geology and geochemistry and health investigations examine the source, dispersion, behaviour, uptake and health impacts of chemical substances in the environment to aid ecosystem management and health protection. In the UK, much of this work has been carried out using the G-BASE and TellusNI  geochemistry datasets. 

BGS is an international leader in the development of methods for the measurement, modelling and understanding of the mobility of chemical substances in the environment and in the determination of the bioaccessibility of potentially harmful substances to aid health hazard assessments.

In addition, extensive medical geology programmes are carried out by the Centre for Environmental Geochemistry  (access the centre’s publications) and by the BGS Groundwater programme.
