Description
This module provides an overview of biogeochemical cycling, associated concepts and terminology together with the chemical, physical and biological processes governing transfer of matter through the environment.
The module is divided into two sections. The first semester will primarily deal with fundamental concepts of biogeochemical cycles including mixing times, residence times, transfer processes focussing on major element cycles (e.g. sulphur, carbon and phosphorus).
The form of elements within the major compartments (soil, air and water) will be considered in terms of speciation, the importance of particulate matter and colloids.
We will also consider ways in which measurements of elements are made within different media together with the importance of stable isotopic analysis.
The second semester will then use fundamental concepts from semester 1 to investigate how anthropogenic impacts affect and alter biogeochemical cycles and how pollutants are transported within different environmental media.
Case studies will be used extensively to illustrate examples; subjects including mining, climate change, acid deposition, pesticides and nanoparticles.
