A fundamental treatment of all aspects of the physical and chemical behavior of air pollutants. Provides a clear analysis of the chemistry of atmospheric pollutants, an extensive treatment of the formation, thermodynamics and dynamics of atmospheric aerosols, and an elementary discussion of atmospheric diffusion with commonly used atmospheric diffusion formulas derived from first principles. Also contains comprehensive coverage of atmospheric removal processes, including wet and dry deposition; statistical distributions of atmospheric concentrations, and a discussion of acid rain. Numerous problems enable students to evaluate their understanding. All major chapters contain up-to-date bibliographies.
