Environmental Chemistry: A Global Perspective provides a comprehensive introduction to the heterogeneous systems in the natural environment. This unique text discusses the chemistry of the atmosphere (air), the hydrosphere (water), and the terrestrial environment (soil) from a global perspective, describing the chemistry of these natural environmental systems, their composition, and the processes and reactions that operate within and between the various components. The systems are also studied in relation to perturbations--both natural and those caused by the developing human population whose wastes, by-products, and life-styles affect many natural chemical processes within these systems. Focusing on basic knowledge and general chemical principles--both descriptive and quantitative--that apply to environmental studies, Environmental Chemistry is ideal for undergraduate courses in environmental chemistry and environmental science. It illustrates concepts with examples drawn from all over the world and includes a broad range of problem exercises.
