The chemistry of heavy metals in natural waters, industrial waste streams, and the environment is influenced by a number of factors including the prevailing matrix, their relative concentrations, and biologically or chemically induced transformations. Speciation, which entails the identification and quantification of all the forms of a metal or any other chemical entity present in a sample, is a necessary step in assessing the toxic and pollution effects and the overall impact of these entities on environmental systems. Analytical methods and protocols that can provide analytical data in the parts per billion concentration range and below are needed for these kinds of measurements. The thrust of this research was to develop metal speciation methods and techniques using direct current plasma (DCPAES) in combination with ion chromatography (IC), whereby the DCPAES serves as an element selective detector (ESD) for the metal species separated in the chromatographic column. While the metal speciation work carried out in this program has utilized the IC-DCPAES as the primary analytical measurement tool, other sample processing and preparation approaches have also been developed to enhance the effectiveness and capability of the chromatographic-element selective method of metal speciation. Post-column derivatization and solid phase extraction are two protocols which were incorporated with IC-ESD with significant improvements in the capability of the method.

The aim of this volume is to describe the most recent advances in areas of analytical chemistry that relate to the trace determination of metals and inorganics, as well as their distribution and forms (species) present, sample dependent. Analytical approaches are described that encompass a number of separation methods, such as gas and high performance liquid chromatography, interfaced with selective and sensitive detection methods that become unique for metal species/forms present in various samples. Hyphenated techniques are emphasized, such as interfacing HPLC with plasma induced emission spectroscopy, electrochemistry, post-column reaction chemistry, etc. Each chapter describes the latest instrumental and methodology advances that utilize some form of chromatography together with element-specific detection or mass spectrometry to provide absolute identification of the specific species of a metal present in various samples. The book will be of value to those concerned with the determination of trace levels of individual metal species present or suspected present in any given sample and to those involved in trace metal toxicology, metabolism of metal-containing drugs or chemicals, environmental exposures to metals and chemical speciation of real world samples. Government regulatory laboratories striving to detect and determine absolute levels of a metal species in any regulated sample will be interested in this volume, as will academic institutes involved in environmental toxicology, environmental chemistry, metal-DNA/protein interactions and researchers working with metal species.

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.

single toxicant before it, yet one that has now been brought under effective control-at least in estuaries and the nearshore environment. The problem with TBT and its cause was first recognized in France, then in the United Kingdom and the United States of America; and in these and other countries legislation is now in place (see Abel, Chapter 2; Champ and Wade, Chapter 3), but in many countries the hazard is only now being identified. This volume has the important function of making available to all a summary of the results of work on TBT and the main conclusions. It will help to minimize the duplication of research and speed the introduction of legislation around the world to control organotin pollution. It is the more valuable because research on TBT has often been published in less accessible journals and symposium proceedings. This volume brings together accounts of these findings by the major contributors to the TBT story, providing the most comprehensive account to date. The TBT problem has proved to be instructive in a number of different ways beyond the bounds of the specific issue (Stebbing, 1985). Most important is that TBT can be seen as a challenge to monitoring systems for nearshore waters, by which it can be judged how effective monitoring has been in fulfilling its purpose, and what improvements should be made. Most instructive was the time it took to bring TBT under control.

This work details minor, trace and ultratrace methods; addresses the essential stages that precede measurement; and highlights the measurement systems most likey to be used by the pragmatic analyst. It features key material on inclusion and phase isolation. The book is designed to provide useful maps and signposts for metals analysts who must verify that stringent trace level compositional specifications have been met.
