Many wetlands around the world act as sinks for pollutants, in particular for trace elements. In comparison to terrestrial environments, wetlands are still far less studied. A collaborative effort among world experts, this book brings the current knowledge concerning trace elements in temporary waterlogged soils and sediments together. It discusses factors controlling the dynamics and release kinetics of trace elements and their underlying biogeochemical processes. It also discusses current technologies for remediating sites contaminated with trace metals, and the role of bioavailability in risk assessment and regulatory decision making. This book is intended for professionals around the world in disciplines related to contaminant bioavailability in aquatic organisms, contaminant fate and transport, remediation technologies, and risk assessment of aquatic and wetland ecosystems.

Nickel (Ni), the fifth common element on the earth is widespread in the environment. Recently Ni has been proved essential for normal growth of many organisms, and at the same time Ni can become toxic to organisms when high in concentration. In several parts of the world, high Ni concentrations are causing serious environmental impacts. This book will be the first to discuss the problems related to Ni presence and raise the need for full investigation and more efforts to support this goal. It will present the recent advances in research on Ni nutrition of plants, Ni contamination of the environment--that is, soils, waters and plants--and methods of remediation.

This third edition of the book has been completely re-written, providing a wider scope and enhanced coverage. It covers the general principles of the natural occurrence, pollution sources, chemical analysis, soil chemical behaviour and soil-plant-animal relationships of heavy metals and metalloids, followed by a detailed coverage of 21 individual elements, including: antimony, arsenic, barium, cadmium, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, selenium, silver, thallium, tin, tungsten, uranium, vanadium and zinc. The book is highly relevant for those involved in environmental science, soil science, geochemistry, agronomy, environmental health, and environmental engineering, including specialists responsible for the management and clean-up of contaminated land.

Advances in Microbial Ecology was established by the International Committee on Microbial Ecology (ICOME) to provide a vehicle for in-depth, critical, and even provocative reviews to emphasize recent trends in the important field of microbial ecology. Advances in Microbial Ecology is now recognized as a major source of infor mation and inspiration both for practicing and for prospective microbial ecologists. Most reviews appearing in Advances have been prepared by leaders in particular areas follow ing invitations issued by the Editorial Board. Individuals are encouraged, however, to submit outlines of unsolicited contributions to any member of the Editorial Board for consideration for publication in Advances. With the publication of Volume 12 of Advances in Microbial Ecology there will be a change of Editor and the entire Editorial Board. The current Editor wishes to take this opportunity to thank the present Editorial Board, Ron Atlas, Bo Barker J~rgensen, and Gwyn Jones, as well as past members of the Board, for their assistance and encourage ment over the years. The new Editor of Advances in Microbial Ecology will be Gwyn Jones, with Bernhard Schink, Warwick F. Vincent, and David M. Ward as members of the Editorial Board. The outgoing Board wish the new Board every success in continu ing the traditions established by Martin Alexander, the founding Editor of Advances in Microbial Ecology. The topics featured in Volume 12 of Advances include some related to the meta bolic activities of bacteria; namely, bioremediation of oil spills, by R. M. Atlas and R.

When sediments are agitated by dredging and subsequent resuspension in water by discharge operations, there is a possibility that large amounts of some chemicals in the sediment could be released into the water column. To better understand the short- and long-term release effects of sediment resuspension on water quality, a functionally derived sediment selective extraction procedure was developed. This procedure explores the association of trace metals and other elements or compounds within sediments and their distribution among sediment phases of various stability and mobility. The effect of these sediment fractions or extractable phases upon water quality as indicated by the standard elutriate test and the relation of elutriate concentrations to these fractions was thoroughly investigated. The sediment chemical partitions studied in the selective extraction procedure were those dissolved or in solution in sediment interstitial water; sorbed on sediment mineral and organic material (exchangeable); occluded, co-precipitated, or bound within iron and manganese oxide and hydroxide partitions; bound in organic matter as complexes and compounds precipitated as sulfide salts; and occurring as an extremely stable residual partition in mineral crystalline lattice. Results of the sediment partitioning fractionation scheme showed that these operationally or functionally defined phases in a sediment could be isolated with good elemental mass balance and precision among the phases.
