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.

"Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.

Report, the editors replaced the term "speciation" wherever it occurred by "identification and quantification," or "description of abundance," or "reactivity," or "transformation" of a chemical species, according to whichever one of the four meanings the author had evidently meant to convey. In line with the Dahlem Workshop Model, this Report comprises the background papers written in advance of the meeting on the current status of problems in environmental research and on advanced analytical tech niques for the identification and quantification of chemical species, as well as the group reports summarizing the results of the discussions held during the meeting. Each group report was prepared during the meeting by one "rapporteur" with the help of members of that group and finalized by the rapporteur (listed as the first author of the group report) after the meeting, taking into account both verbal comments made during the presentation of the reports in the plenary session at the end of the workshop and written comments received afterwards.

Clearly explains how to more effectively decipher and predict contaminant fate in the environment by combining kinetic methods and molecular-scale spectroscopic and microscopic techniques to analyze mineral/water interfacial reactions in situ. The book begins with a broad overview, then continues with three sections written by internationally known expert. The first deals specifically with spectroscopic/microscopic techniques that can be used in combination with macroscopic approaches to glean mechanistic information on mineral/water reactions and processes. The second section emphasizes computer models that are used to elucidate surface mediated reaction mechanisms. The remainder of the volume is organized around reaction type, including sorption/desorption of inorganic species, sorption/desorption of organic species, precipitation/dissolution processes, heterogeneous electron transfer reactions, photochemically driven reactions, and microbially mediated reactions. Mineral-Water Interfacial Reactions will be a valuable resource for environmental scientists, geochemists, soil chemists, microbiologists, and marine engineers who need to be familiar with the most current and effective methods for testing and controlling the mobility, speciation, and bioavailability of contaminants in the environment.

Past generations of industrial development and chemical production are still very much with us-through contaminants they've left in all phases of the ecosystem. Especially vulnerable to this damage: water. Professionals from various disciplines in environmental sciences are becoming increasingly involved in water quality issues. The Manual of Bioassessment of Aquatic Sediment Quality now provides the most current techniques and methods, in the laboratory and the field, to detect and evaluate aquatic contaminants. Designed to complement the analytical methods presented in the companion volume, Manual of Physico-Chemical Analysis of Aquatic Sediments, the Bioassessment edition offers a comprehensive review of chemical forms, encompassing different elements and compounds in sediments, along with evaluation of their availability to aquatic biota. A discussion about the use of reference materials in sediment analysis also accompanies a review of laboratory safety measures. While greater environmental conscientiousness has led to sustainable industrial development and the recycling of materials, there remains the "hidden need" to remediate contaminated water sources throughout the world-essential to the continued survival of all life. The Manual of Bioassessment of Aquatic Sediment Quality will help environmental professionals ensure the protection of life-supporting streams, lakes and oceans throughout the world.

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.
