This course examines the fundamental chemical processes of the Earth’s natural environment, and changes induced by human activity. Topics covered are related to the atmosphere and the hydrosphere: urban air pollution, stratospheric ozone depletion, acid rain, climate change, water resources and pollution, wastewater analysis, biogeochemistry, and inorganic metals in the environment. Skills in data analysis and visualization will be developed through an introduction to the R programming language and its use in several assignments.
