Geochemical baselines and medical geology


 

Geochemical baselines

GeochemicalBGS is working towards providing comprehensive baseline data on the chemistry of the UK surface environment, thus improving our understanding of the sources and behaviour of chemical substances in the surface zone. Information gained from the analyses of hundreds of thousands of samples of stream water, stream sediment and soil, allows high-resolution mapping of chemical baselines in both rural and urban environments. Applications of this data are diverse and include:

  • exploration for minerals
  • mapping environmental change
  • support for environmental policymakers and regulators
  • underpinning scientific studies into possible environmental causes of human health and agricultural problems

The Geochemical Baseline Survey of the Environment (G-BASE) project is the national capability in high-resolution geochemical mapping in the UK.

This is study of the relationship between natural geological factors and health in man and animals, and the influence of ordinary environmental factors on the geographical distribution of such health problems. The team has a wide ranging research portfolio including

  • international studies on the geological controls on deficiency and toxicity of selenium and iodine in human health
  • measurement and spatial distribution of the bioaccessibility of potentially toxic elements (e.g. As, Pb, Cd) and organic substances (e.g. PAH and PCB) in soils
