The lecture and laboratory portions of this course will highlight sorption and phase partitioning; hydrolysis reactions; convective/diffusive transport; properties and behaviour of particles, including sedimentation, coagulation, and light scattering; and the significance of particulate matter in the atmosphere. Quantitative calculations will be emphasized. The lecture component will provide theoretical background for experiments and instrumentation used for chemical measurements. The course also includes an independent, student-designed air quality monitoring project. Prerequisites: CHEM 263; CHEM 213 or 298 or 313; CHEM 303 or 373. Note: Restricted to students in the Environmental Physical Sciences and Chemistry (Honors, Specialization, and General Science with concentration in Chemistry) programs.
