Book Description
The particular behavior of trace metals in the environment is determined by their specific physico-chemical form rather than by their total concentration. The introduction of atomic absorption spectrometry has lead to a plethora of scientific papers and reports in which metal concentrations in the environment are only reported as total concentrations. Only recently has the need for improved knowledge on the various forms and bioavailability of metals been realised. Considerable research effort is now devoted to measuring the concentrations of trace metals in surface waters. Efforts are made to couple chemical analytical techniques to process-related biological problems. The proceedings of the workshop on The Speciation of Metals in Water, Sediment and Soil Systems held in Sunne, Sweden, comprise these efforts and show aspects for further cooperation between analytical chemists and biologists.

Book Description
Here is an up-to-date presentation of metal speciation in soils, sediments, and water by specialists in analytical chemistry, environmental engineering, oceanography, nutrition, and soil chemistry. fate and effects-measurements-and modeling-are the major themes in this book, with overviews and examples of the significance of metal speciation to solving environmental problems, and recommendations for additional research areas. This new reference discusses separation methods, extraction techniques; bioavailability as related to humans, plants, and aquatic organisms; applications showing importance of speciation in groundwater; industrial waste treatment systems, marines and lakes, solid-solution interface; fate of organic pollutants; nature of surfaces; binding of metals to oxides and sediments (dissolved and particulate matter); interpretations of reactions in multi-ligand systems.

Book Description
This book presents new results on metal fluxes from society to the environment, on metal speciation in water, soil and sediment, and its mobility, biological uptake and toxicity. New approaches, like the Acid Volatile Sulphide (AVS) concept to predict metal bioavailability in sediments, and the Biotic Ligand Model to calculate the toxicity of metals to aquatic organisms, are critically evaluated, with a focus on copper, nickel, zinc, and, chromium.

Book Description
Metal Speciation and Contamination of Soil provides a thorough overview of the biogeochemical processes governing the behavior, transport, and bioavailability of heavy metals in contaminated soils and suggests alternative approaches for effective remediation. This important new book contains contributions from experts in various disciplines who explore the issues from theoretical, experimental, and pragmatic perspectives. Topics include redox chemistry, kinetics of metal reactions, spectroscopic characterization of metal ion reactions at surface, modeling hydrologic transport phenomena and colloid-associated transport of metals through the soil profile to ground water, and remediation alternatives.

Book Description
Numerous applications of heavy metal have caused to their wide contamination in the environmental system and raised serious concerns over potential harmful effects on public health and the environment. Water, sediment, and dietary food are the main exposure media of heavy metal pollution and key determinants of adverse human and environmental health effects. Heavy metal(s) toxicity and speciation involve various mechanistic features with specific media and some of them are not clearly investigated. In particular, biological effects such as toxicity are not related to the total concentration of heavy metals in media, and many laboratory and field studies have supported this supposition. Organisms respond to the bioaccessible and bioavailable fraction of metals only, not the total concentration. The bioaccessibility and bioavailability of toxicants are dependent on chemical properties of the contaminant, the many exposure pathways, and temporal variability of these variables with respect to uptake by the target organism. Usually, bioavailable fractions are estimated using chemical or biological approaches. For this study, biological approaches were performed to better ascertain the toxic effects of heavy metals on organisms. A better understanding of bioaccessibility and bioavailability can be a useful tool in exposure and risk assessment. Therefore, this study presents experimental designs focusing on assessing of the bioaccessibility and bioavailability of metals in aquatic, benthic organisms and dietary food. This study also examines the role of metal mixtures on the adverse effects of metals.

Book Description
This book presents a combined analysis of the geochemical, physio-chemical, biological and analytical techniques to provide a better understanding of the biogeochemical cycling of heavy metals in ex-mining areas. The findings presented in this book provide a basis for evaluation of the environmental impacts of mining activities, especially tin mining. The chapters provide a general picture of the land use, geography, concentration and chemical speciation of heavy metals in mining areas. The impacts of bioavailable metal species are supported by a detailed case study on Bestari Jaya. The book concludes with remediation methods along with classical and modern approaches, their limitations and economic feasibility.
