This course introduces environmental chemistry, concentrating on the chemical impact of the environment on human health and activities, and in turn, the chemical effects of people on the environment. Aspects of water and air quality are discussed in detail, as well as the involvement of microorganisms with this chemistry. Some of the major chemical equilibria naturally present in air, water, and soil are investigated.

Topics include:

• the chemical processes that lead to environmental problems such as eutrophication of water supplies, photochemical smog, the greenhouse effect, stratospheric ozone depletion, acid rain and pesticide contamination.
• the chemical parameters that affect water quality, including dissolved gases, acidity, water hardness, phosphate and nitrate contributions
• the basic concepts of microbially-mediated chemical processes and how they impact on water quality and soil chemistry
• the environmental significance of different forms of heavy metals, particularly those of mercury and lead.

Note: This course is delivered online.

On satisfying the requirements of this course, students will have the knowledge and skills to:

Assessment will be based on:

• 3 topic quizzes (5% each, totalling 15%; LO 1, 2, 4)
• Written report on laboratory-based experiment measuring aspects of water quality, evaluating the results and putting them into context (30%; LO 1, 2, 3)
• Written assignment addressing a choice of 5 out of 7 questions relating to soil chemistry (15%; LO 1, 2, 4)
• 3000-5000 word literature-based research essay investigating a student-nominated environmental issue (40%; LO 1, 2 4, 5)
