Learning Outcomes

On sucessful completion of this module, students should be able to demonstrate :-

  • knowledge of geochemical mapping and monitoring and their applicability to environmental problems
  • general basic knowledge of element behaviour in the secondary environment and an understanding of some of the problems caused by anthropogenic activities
  • general ability to estimate the role of human intervention in the environment
  • knowledge of the role of environmental geochemistry on human and animal health

Aims

To introduce the concept of geochemistry of the total environment and outline some of the problems posed to the biosphere.
