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.

Soils with high Ni contents occur in several parts of the world, especially in areas with ultramafic rocks which cause serious environmental impacts. This book aims to extend the knowledge on the risks and problems caused by elevated Ni contents and to cover the existing gaps on issues related to various aspects and consequences of high Ni contents in soils and plants. Nickel in Soils and Plants brings together discussions on Ni as a trace element and as a micronutrient essential for plant growth and its role in plant physiology. It analyzes the biogeochemistry of Ni at the soil plant interface, and explains its behavior in the rhizosphere resulting in Ni deficiency or toxicity, or Ni tolerance of various Ni hyperaccumulators. Included are Ni resources and sources, the origin of soil Ni, its geochemical forms in soils and their availability to plants, a special reference on soils enriched with geogenic Ni, such as serpentine soils, and the special characteristics of those ecosystems. Recent advancements in methods of Ni speciation, including the macroscale and X- ray absorption spectroscopy studies as well as serious views on Ni kinetics, are also covered. Written by a team of internationally recognized researchers and expert contributors, this comprehensive work addresses the practical aspects of managing Ni in soils and plants for agricultural production, and managing soils with high Ni levels by using organic and inorganic amendments. The text also addresses practical measures related to Ni toxicity in plants, the removal and recovery of Ni from high Ni wastes, and offers environmentally friendly innovative processes for mining Ni from soils containing high Ni levels.

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.

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.
