Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

Aquatic and Surface Photochemistry provides a broad overview of current research in the emerging field of environmental aquatic and surface photochemistry. Selected reviews and current research articles are blended to provide an in-depth treatment of various aspects of this research area. The first part of the text deals with photochemistry in the environment, covering recent research on the following topics: aquatic photochemistry of organic pollutants and agrochemicals, photochemical cycling of carbon and transition metals (especially iron), photochemical formation of reactive oxygen species in natural waters, photoreaction in cloud and rain droplets, and photoreactions on environmental surfaces (soil, ash, metal, oxide). The second part provides discussions and data on both heterogeneous photocatalytic and homogeneous processes, with topics ranging from applications to mechanistic studies. These chapters illustrate the wide diversity of pollutant classes that are degradable by photochemical techniques and the effects of various reaction conditions on the rates and efficiency of the techniques. Current kinetic studies are presented, which provide new information about the role of adsorption and the nature of the reactive oxidizing species that mediate these photoremediation processes.This book will interest civil, chemical, and environmental engineers, as well as chemists, soil scientists, geochemists, and atmospheric chemists.

Chemical Kinetics and Process Dynamics in Aquatic Systems is devoted to chemical reactions and biogeochemical processes in aquatic systems. The book provides a thorough analysis of the principles, mathematics, and analytical tools used in chemical, microbial, and reactor kinetics. It also presents a comprehensive, up-to-date description of the kinetics of important chemical processes in aquatic environments. Aquatic photochemistry and correlation methods (e.g., LFERs and QSARs) to predict process rates are covered. Numerous examples are included, and each chapter has a detailed bibliography and problems sets. The book will be an excellent text/reference for professionals and students in such fields as aquatic chemistry, limnology, aqueous geochemistry, microbial ecology, marine science, environmental and water resources engineering, and geochemistry.

Aquatic Chemistry An Introduction Emphasizing Chemical Equilibria in Natural Waters Second Edition Edited by Werner Stumm and James J. Morgan This second edition of the renowned classic unites concepts, applications, and techniques with the growing amounts of data in the field. Expanded treatment is offered on steady-state and dynamic models employing mass-balance approaches and kinetic information. New chapters address such topics as: environmental aspects of aquatic chemistry; new material on organic compounds in natural water systems; the use of stable and radioactive isotopes in chemical and physical processes; the latest advances in marine chemistry; solid-solution interface; kinetic considerations of equilibria; metal-ligand interactions; and an expanded compilation of thermodynamic data for important reactions in natural water systems. 1981 (0 471-04831-3) Cloth 780 pp. (0 471-09173-1) Paper Chemical Processes in Lakes Edited by Werner Stumm This is a multidisciplinary analysis of recent research on the physical, chemical, and biological processes in aquatic systems. Coverage includes: distribution of elements and compounds in water and sediments; sedimentation and sediment accumulation of nutrients and pollutants; eurtophication and acidification; atmospheric deposition; redox-related geochemistry and sediment-water exchange of nutrients and metals; sediment dating and paleolimnology; and steady-state and dynamic models. Most chapters focus on the role of biological processes and the coupling of elemental cycles by organisms. 1985 (0 471-88261-5) 435 pp. Principles of Aquatic Chemistry Francois M. M. Morel Here is a quantitative treatment of the chemical principles that govern the composition of natural waters. Features include an in-depth examination of the use of conservation principles in chemical systems, a review of thermodynamic and kinetic principles applicable to aquatic systems, and a novel presentation of a systematic methodology for equilibrium calculations. Detailed coverage is provided on the topic of aquatic chemistry, following the traditional divisions of acid-base, precipitation-dissolution, coordination, redox and surface reactions. 1983 (0 471-08683-5) 446 pp.
