Description

This unit aims to give students an understanding of the biogeochemical processes that couple the lithosphere, hydrosphere, atmosphere and biosphere. We will also focus on the chemistry controlling the behaviour of pollutants in soil, groundwater and surface water. This unit will provide the chemical background for the contaminant transport course. Specific aims are to provide a baisc understanding of:

  • biogeochemical processes
  • carbon geochemistry and carbonate equilibria
  • weathering reactions
  • sorption and ion-exchange reactions that on the chemical compositions of natural waters
  • the chemistry of the oceans, rivers, lakes and groundwaters
  • the major organic and inorganic pollutants in soil and groundwater and the biogeochemical controls on their fate.

Intended learning outcomes

On completion you should be able to:

  • do simple chemical equilibrium calculations to predict concentrations of dissolved chemical components in aqueous solutions.
  • describe the geochemical controls on the compositions on natural waters
  • predict the fate of important environmental pollutants
  • give a qualitative account of the geochemical cycles of C and N.
  • explain the origin of acid mine drainage

Lectures and practicals

Assessment Details

The course will be assessed from a 2-hour closed examination. This will cover both concepts presented in lectures and calculations learned in practicals.
