environmental problems , causes and sources of pollution. Air
pollution (emission limits and concentrations, law, effects on
health, primary and secondary pollutants, meteorology, atmospheric
dispersion). Indoor air quality (concentration levels, ventilation).
Air pollution control equipment. Equipment and methods for measuring air pollutant
The course involves optional coursework (35% weighted) using EPA's AERSCREEN software for pollutant dispersion evaluation
or using a selection of mobile measuring instruments for indoor or outdoor air quality.
