Methods for Environmental Trace Analysis

by John R. Dean

Published 14 January 2003

Provides the basic skills and information required to prepare an environmental sample for analysis. Divided into two sections, i.e. Inorganic Analysis and Organic Analysis, this book covers selected techniques, principally atomic spectroscopy and chromatography. Using flow diagrams to augment the experimental information, it highlights the most appropriate methods and the likely results. * Detailed experimental information provided in an easy-to-follow style with illustrations * Describes the specific sample preparation approaches necessary to analyse a particular sample type * Discussion of selected literature sources highlights the most appropriate methods and the likely results obtained

Practical Inductively Coupled Plasma Spectroscopy

by John R. Dean

Published 1 January 2005

The book provides an up-to-date account of inductively coupled plasmas and their use in atomic emission spectroscopy and mass spectrometry. Specific applications of the use of these techniques are highlighted including applications in environmental, food and industrial analysis. It is written in a distance learning / open learning style; suitable for self study applications. It contains contain self-assessment and discussion questions, worked examples and case studies that allow the reader to test their understanding of the presented material.

Bioavailability, Bioaccessibility and Mobility of Environmental Contaminants

by John R. Dean

Published 1 January 2007

This book covers all aspects of bioavailability, as related to environmental contaminants. After a discussion of the definition of bioavailability and its context, focus is placed on the role of risk assessment and bioavailability. Methods of analysis are then discussed including a range of atomic spectroscopic and electrochemical techniques for metal analysis and chromatographic approaches for persistent organic pollutants (POPs). The occurrence, properties and eco-toxicity of POPs and metals in the soil/sediment environment are discussed. Particular emphasis is placed on the uptake of POPs and metals by plants (phytoextraction). Examples of POPs and metals in the environment are reviewed.

Methods to assess the bioavailability of POPs and metals in the environment are discussed. The particular approaches considered are:

• non-exhaustive extraction techniques
• single extraction techniques
• sequential extraction techniques
• use of cyclodextrin and surfactants
• in-vitro gastrointestinal methods including physiological-based extraction test
• the use of bioasssays including earthworms.

Finally, selected case studies highlight the importance of determining the bioavailability of POPs and metals.

Extraction Techniques in Analytical Sciences

by John R. Dean

Published 27 November 2009

Increasing environmental regulations have resulted in the need for new methods of analysis for environmental samples. As an updated version to Extraction Methods for Environmental Analysis published in 1998, Extraction Techniques in Analytical Science provides the fundamentals of extraction methods in environmental organic contaminants. The text explores topics like aqueous samples, solid samples, gaseous samples, comparisons of extraction methods, and resources. Also, the book discusses methods of analysis, including chromatographic approaches for environmental organic analysis. Written in the AnTS style, this text is ideal for students as a self-study guide.
