Course Details and Policies

CH217: Environmental Chemistry

Students in Environmental Chemistry will develop an understanding of how physical, chemical and biological processes in the environment create and define the natural world.   As a chemistry course the focus is on the fundamental equilibrium and kinetic processes that control the global systems of the Earth including the composition of the atmosphere, ocean, and biosphere.   Building on the concept of residence time and chemical reactivity students learn how to evaluate the impact of anthropogenic modifications to the environment over a range of spatial and temporal scales. Current topics such as acid deposition, global warming, atmospheric ozone loss, and the fate and toxicity of heavy metals are discussed in the context of natural environmental processes.  Lectures and homework focus on problem solving skills that provide solutions to new environmental problems based on fundamental chemical principles and constants.
