CE 579 Principles of Air Quality Engineering
3 Credit Hours
The topics covered in this course include air quality management issues, sources of air pollutants, atmospheric physics and chemistry and their relationship to pollutant transport and transformations, air quality meteorology, and air pollutant dispersion modeling. Students will learn about the major types of regulations that motivate the need to estimate and measure atmospheric air quality, the major types of pollutants that are regulated by such air quality standards (e.g., sulfur oxides, nitrogen oxides, particulate matter, carbon monoxide, tropospheric ozone, and lead), the major emission sources for such pollutants, the role of anthropogenic and biogenic sources in global chemical cycles, gas and aqueous-phase chemistry in the atmosphere, basic principles of meteorology as applied to air quality (including energy balance, winds, temperature, equations of motion, and atmospheric diffusion), the fundamentals and practical aspects of commonly used air quality models and linkages between air pollution and global climate change.
Prerequisite
It is assumed that you have had a college-level chemistry course and that you are familiar with basic calculus and reaction kinetics.
Course Objectives
Students completing this course will be able to: (1) identify major types of air quality problems based upon types of pollutants, chemical transformations, and temporal and spatial scales; (2) apply mass and energy balance, chemical equilibrium, and chemical kinetic concepts to estimating pollutant emission rates; (3) apply similar concepts to estimating the formation of secondary pollutants (e.g., ozone); (4) classify, compare, and evaluate alternative air quality models; (5) develop and apply simplified air quality models for both non-reactive and reactive pollutants; and (6) identify and evaluate control strategies for mitigating atmospheric air pollution problems.
