Summary module description:

The aim of this module is to further students' awareness and understanding of selected key topics in the chemistry of the environment.

Assessable learning outcomes:
Students should be able to:
• Describe and discuss the subject matter of the module, and explain the concepts raised within it.
• Critically examine the evidence related to Man's impact on the environment.
• Evaluate information obtained in the literature and synthesise it into a critically argued case.

Additional outcomes:
Through the preparation and presentation of the report students will improve their library/database skills, writing skills and oral and presentation skills. The preparation of the poster will also improve their team working skills.

Outline content:
C. Pfrang (5 lectures) Environmental Atmospheric Chemistry
A range of current issues of importance in the atmosphere are examined, including photochemical smog formation, ozone depletion, the Antarctic ozone hole, global warming and climate change.

F J Davis (8 lectures + 2 hour workshop+ 4 hour seminar session) The Environmental Impact of Organic Chemistry
Positive and negative aspects of pest control including a discussion of the impact of organo-chlorine based insecticides and the use of less persistent alternatives; including organo-phosphorous based materials and pyrethroids and the development of more specific materials including pheromones and Juvenile hormone. Other aspects where organic chemistry interacts with everyday life are discussed with particular reference to recycling and additives.

J M Elliott (2 lectures + 2 x 1 hour workshop + 1 x 2 hour workshop)
Applications of chemical principles (solubility products, pH, redox potentials (Eh), the Nernst Equation and Eh versus pH diagrams) to environmental systems will be covered. The carbon dioxide-water system and its implications for the environment in terms of acid rain will also be described. Examples of the impact that mining sites can have on the environment will be given, and interactive workshops on the anthropogenic factors that govern water quality will be undertaken.

Brief description of teaching and learning methods:

Approximately two one-hour lectures per week, plus workshops in the Autumn Term. In addition, students will prepare a substantial report on selected areas of environmental chemistry. Students will also work as a team to produce a poster.

Formative assessment methods:

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at:
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

    Length of examination:
    1.5 hours

    Requirements for a pass:
    A mark of 40 % overall.

    Reassessment arrangements:
    Reassessment will comprise of an examination worth 60%, a written essay worth 20% and a oral presentation worth 20%.
