Over the past decade the sediments of many rivers, lakes, and estuaries have been contaminated by inorganic and organic materials. Contaminants from sediments, under certain conditions, can be released into overlying waters. Thus, sediments may be an important source of contaminants to waters in which littoral and atmospheric contaminants have been reduced or eliminated. Often found in aquatic sediments, metals are exposed to many reactions, such as sorption and precipitation, and are greatly influenced by the redox conditions in the sediment. The reactions - usually over a period of time - reflect biotic processing as well as chemical transformations. This book describes these important processes. Metal Contaminated Aquatic Sediments outlines advances in environmental chemistry, effective new modeling techniques, applications for biological treatment, and cycling and transport of trace metals in sedimentary environments. Each chapter contains a detailed reference section that draws upon a stunning array of sources. The book includes many figures and tables that illustrate the process under discussion. Features
The major theme of the May 1995 conference was the challenge facing water resource professionals to develop and implement decision-making approaches that integrate the numerous objectives and constraints in reaching balanced water management strategies. Papers cover such topics as urban drainage and stormwater; water rights and policy; watersheds and wetlands; water pollution control; water supply planning and management; economics, flood control, and risk assessment; water conservation and stochastic hydrology; information resources; and NAFTA.
