Air quality management is fundamental to human health and environmental stewardship. This course provides a systematic introduction to the air quality management cycle and how it is applied to protect both outdoor and indoor air quality as well as to mitigate climate change. Air pollutants pose risks at multiple spatial scales—from individual homes to regional and global geographies—and across various timelines—from hours to decades. This course describes the formation, transport, and transformation of air pollution and reviews the historical development of air pollution control programs. As science and technology evolve, the principles of air quality management enhance our ability to protect and restore healthful air quality and address both long-standing and emerging issues. Students will learn how air quality management principles shape and enable a variety of strategies to minimize negative impacts of traditional and newly developed air contaminants. Assignments emphasize analyzing air quality measurements and emissions data as well as comparing and contrasting regulatory approaches. Through a term project students apply knowledge of the principles of air quality management to timely and relevant air quality issues.
