Chemical Speciation in the Environment

Interest in the topic of chemical speciation has grown markedly since the publication of the first edition of this book in 1995. It is increasingly realised that the distribution, mobility and biological availability of chemical elements depend not simply on their concentrations but, critically, on the forma in which they occur in natural systems. Continuing developments in analytical chemistry have made speciation practicable even where analytes are present at trace levels (as is often the case in natural samples).
In the second edition, the expertise of scientists involved in chemical speciation in various fields has been brought together to provide an overview of the current status of speciation science and to indicate how the field may develop in the future. In Part 1, the book deals with methodologies for speciation analysis. Part 2 deals with elemental speciation in particular compartments of the environment. In addition to extensive updates of existing chapters, this new edition includes three new chapters on: quality control, the marine environment and single and sequential soil extraction.

Nota biograficzna:
Dr. A. M. Ure was until recently Head of the Department of Spectochemistry in the Macaulay Institute for Soil Research in Aberdeen, Visiting Lecturer in the Department of Pure and Applied Chemistry in the University of Strathclyde in Glasgow and Consultant to the Bureau Communautaire de Référence (now Standard Measurements and Testing Programme) of the European Community, in the development of methods for the preparation of soil and sediment Reference Materials. Since his retirement he is a Visiting Researcher at Strathclyde Univesity. He holds the degrees of BSc (Hons) Chemistry, PhD and DSc from the universities, respectively, of St. Andrews, Aberdeen and Strathclyde.
Dr C. M. Davidson is a Senior Lecturer in analytical chemistry at the University of Strathclyde and leads a research group focussing particularly on the determination of heavy metals and natural radionuclides. She obtained her BSc (Hons) and PhD from the University of Glasgow, and undertook postdoctoral work at the State University of Utrecht, Netherlands, and the Scottish Universities Research and Reactor Centre.
