Errata sheet for the textbook 

Graduate School Listing:
ENVR 416  Aerosol Technology (4).  Prerequisite, admission to the Department of Environmental Sciences and Engineering, or permission of the instructor.  Physical and chemical principles underlying behavior of particles suspended in air.  Rectilinear and curvilinear motion of particles in a force field, diffusion, evaporation, and condensation, electrical and optical properties and particle coagulation.  Three lecture hours a week, with several laboratory assignments. Fall.   

The objective of this course is to discuss aerosols, and their relationship to problems in environmental engineering, air pollution control, atmospheric chemistry and industrial hygiene.  The course requires knowledge of calculus and college-level physics.
