Postgraduate Course: Environmental Geochemistry (PGGE11172)
|School||School of Geosciences
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Not available to visiting students
|Summary||This course consists of 14 one-hour lectures and 6 one-hour examples class/case study/presentation sessions. The lectures cover the main characteristics and geochemical processes of soils, a fundamental treatment of acid-base equilibria in aquatic systems, and an integrated approach to redox and complexation equilibria in soil waters. The other sessions are devoted to discussion of case studies which provide 'real-world' application of the theory covered in the lectures and to student presentations and problem-solving workshops.
Characterisation of soils and sediments
Soil properties, erosion and forensic science
Mineral surface properties and cation exchange capacity
Instrumental methods for mineral characterisation in environmental samples
Characterisation of natural organic matter in soils and sediments
Transformations of organic matter: formation of fossil fuels
Composition of soil porewaters
Interaction of porewater organic contaminants with solid phase soils and sediments
Examples - soils and sediments
Feed forward - oral presentations
