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

Outline content:
G Marston (5 lectures) Environmental Chemistry of Aqueous Solutions
The carbon dioxide-water system will be examined at various different complexities, using a range of methods to solve the equations that result. The implications for the environment in terms of acid rain and how this impacts differing locations will be developed.

G Marston (5 lectures) Environmental Atmospheric Chemistry
The chemistry of a range of issues of importance in the atmosphere are examined, including photochemical smog, ozone depletion and the Antarctic ozone hole, climate change and acid rain.

F J Davis (10 lectures) 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 include antibiotics, dyestuffs and artificial sweeteners are considered. A discussion of the meaning and quantification of toxicity is followed by a description of the problem of the disposal of organic chemical waste.

M J Almond (3 lectures + 2 x 2 hour workshops) Applications of chemical principles to environmental systems.
Solubility products; electrode potentials and the Nernst Equation - Eh versus pH diagrams. Applications to polluted waters. The specific examples of pollution from the Devon Great Consoles mine, UK and the Rio Tinto mine, Spain will be considered.

Brief description of teaching and learning methods:
Approximately two one-hour lectures per week, plus workshops in the Summer Term.
In addition, students will prepare two substantial reports on selected areas of environmental chemistry, and present a talk.
