Full Title:Environmental Chemistry
Module Code:53606
 
Credits: 7.5
Valid From:Semester 1 - 2013/14 ( September 2013 )
Module Delivered in 2 programme(s)
Module Description:Following this course, students will be able to critically synthesise and analyse the chemical processes that occur in the environment, with reference to the impacts of various natural and human inferences on associated biogeochemical cycles.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Appraise the role of environmental chemistry and biochemistry in the geosphere.
  2. Evaluate the fundamental processes that drive biogeochemical cycles at a local scale.
  3. Evaluate the effects of human-related pressures on biogeochemical cycles at a global scale, including global climate change.
  4. Describe and relate aspects of environmental chemistry and biochemistry to the physical environment.
  5. Quantify and assess changes in key chemical cycles in the environment.
 

Module Content & Assessment

Indicative Content
Environment and its chemistry
Structure and composition of main spheres in the environment; inter-relation of different spheres.
Atmospheric chemistry
Composition of the atmosphere, chemical processes, solubility of atmospheric pollutants in water; large-scale climate effects, including human related climate change, chemistry of acid deposition. Air quality standards. Gas sampling and analytical techniques.
The lithosphere
Composition and structure; weathering; leaching; soil chemistry; mineral resources and pollution; geochemical solubility.
The hydrosphere
Chemical composition and physical properties; water cycle; equilibria in aqueous systems; water pollution; large-scale human-related effects e.g. ocean acidification.
The biosphere
