Bringing together world-renowned experts in air chemistry and pollution (including 1995 Nobel Laureates in Chemistry, P.J. Crutzen and M.J. Molina), this unique volume analyzes and integrates the scientific evidence behind the myriad issues of air pollution. Tracing the history of air pollution, from localized microenvironments to regional and global levels, it provides important insights into the mean physical and dynamic characteristics of the atmosphere, the effects of population and industry on atmospheric composition, and quantifiable sources of air pollution. Includes extensive coverage of photochemical smog, tropospheric ozone, stratospheric ozone depletion, acid rain, and global warming. Features chapters on ozone chemistry written by recipients of the 1995 Nobel Prize in Chemistry.
