This module focuses primarily upon inorganic geochemistry (notably trace metals) within the secondary environment. The module is concerned with understanding the natural and anthropogenic factors that influence the abundance of toxic and non-toxic elements within the environment. It considers how we can establish 'normal' elemental abundance and how we can establish the presence of potentially toxic elements. The module looks at contamination issues within different environments (riverine & riparian, atmospheric, soils) and the implications for human health and environmental legislation and are considered along with approaches to environmental/geochemical monitoring and implications for environmental management and remediation.
Cynnwys cwrs
- Context and major concepts: key terminology, introduction to the primary environment and natural elemental abundance, importance of mineralization.
- Introduction to the secondary environment. Geochemical behaviour in the secondary environment, cations and valency, processes of sorption, importance of pH and Eh.
- Natural release of metals to the environment: processes of physical, biological and chemical weathering, volcanic activity, determining `background' metal concentrations.
- Mapping of environmental geochemistry and the use of geochemical maps.
- Human activities as sources of metals to the environment: mining, smelting, petrol combustion, waste incineration, use of sewage sludge.
- Geochemistry and human health: toxicity and deficiency.
- The importance of the fluvial environment in pollutant dispersal and storage.
- Remediation techniques.

trothwy
Grade D- to D+ Adequate knowledge of the key concepts in inorganic geochemistry. Presentation of appropriate examples to illustrate geochemical processes. Structured, accurate and relevant description of the impacts of trace metal contamination on environmental and human health. Limited quantification, but with some errors and no critical evaluation.
C- i C+
Grade C- to C+ Adequate understanding and knowledge of the key concepts in inorganic geochemistry but with no or very limited evidence of reading and knowledge of recent developments in the subject. Multidisciplinary issues are not emphasised, with a limited and unbalanced description of natural and anthropogenically-influenced geochemical processes. Mostly accurate quantification but limited critical evaluation. Adequate standard of presentation.
da
Grade B- to B+ Clear understanding and thorough knowledge of the key concepts in inorganic geochemistry with evidence of reading and knowledge of recent developments in the subject. Multidisciplinary issues emphasised, and thoroughly described with a balanced review of natural and anthropogenically-influenced geochemical processes. Thorough quantification and critical evaluation of case studies. High standard of presentation.
ardderchog
Grade A- and above Clear understanding, wide and thorough knowledge of the key concepts in inorganic geochemistry. Evidence of substantial reading, and appreciation of recent and potential future research developments. Multidisciplinary issues emphasised, and thoroughly described with a balanced review of natural and anthropogenically-influenced geochemical processes. Detailed quantification and explanation of derivations. Critical evaluation with well reasoned opinion. Elegant and flowing presentation, with flair for subject.
