Module overview

An introduction to the numerous interlinked chemical processes that take place within the Earth’s environment, and the impact they may have for life on Earth.

Module aims

To provide an introduction to some of the fundamental concepts and principles of environmental chemistry

To provide an introduction to the type of chemical processes occurring naturally and as a result of anthropogenic activities within the atmosphere, biosphere, hydrosphere and lithosphere

To provide an understanding and rationalisation of some of the key environmental problems currently confronting society, and a consideration of possible of the solutions

Module content

Indicative content includes:


Introduction to the environment and environmental cycles. Summary of role of major elements in living matter. Political relevance of environmental issues;

Water: Properties and structures of water and ice; aqueous solutions; ionic product of water, acidity and alkalinity: pH, pOH. Buffers and buffered solutions. Speciation. The water cycle. Purification of waste water: the Camelford incident.


Carbon: The carbon cycle. Photosynthesis and formation of carbon compounds. Organic pollutants in the environment;


Oxygen: The oxygen cycle. Nature and makeup of the atmosphere; atmospheric gas phases reactions;


Nitrogen: The nitrogen cycle. Nitrogen fixation, nitrification denitrification and ammonification. Fertilizers, nitrates in water supply;


Chemistry of polluted atmospheres: ozone, NOx, SOx, photochemical smog, greenhouse effect and global warming;


Sulphur: The sulphur cycle. Remediation;


Phosphorus: The phosphorus cycle. Eutrophication;


Heavy metals such as aluminium, mercury, lead, cadmium and iron within the environment: Cycles, biotransformation, bioaccumulation and speciation;


Radiation and radionuclides in the environment;


Energy: Brief review of methods of energy generation; renewable and non-renewable resources. Nuclear power – the solution to our energy problems?


Methods of Teaching / Learning

The learning and teaching strategy is designed to:



allow students to understand the key processes operating within the environment, relate them to their current understanding of chemistry, and to consider how environmental problems may be foreseen and avoided.



The learning and teaching methods include:


33 lectures
3 tutorials


 

 

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate successful achievement of the learning outcomes.

Thus, the summative assessment for this module consists of:


1.5 hour examination 70% (addresses LOs 1-4)
Coursework (2000-2500) 30% (addresses all LOs)


 

Formative assessment

Students are required to produce a detailed plan for the extended essay; tutorial sessions with problems and/or discussion topics ensure that students engage with the module and are able to measure their own progress with it.

 

Feedback

Detailed feedback is provided on the essay plan and on the extended essay – written on each printed piece of work and using the feedback form. Similar feedback given on the poster and ‘newspaper’ front page generally and individually.
