Overview

Fundamentals of Environmental Sampling and Analysis / Edition 1

An integrated approach to understanding the principles ofsampling, chemical analysis, and instrumentation

This unique reference focuses on the overall framework and whyvarious methodologies are used in environmental sampling andanalysis. An understanding of the underlying theories andprinciples empowers environmental professionals to select and adaptthe proper sampling and analytical protocols for specificcontaminants as well as for specific project applications. Coveringboth field sampling and laboratory analysis, Fundamentals ofEnvironmental Sampling and Analysis includes:

  • A review of the basic analytical and organic chemistry,statistics, hydrogeology, and environmental regulations relevant tosampling and analysis
  • An overview of the fundamentals of environmental samplingdesign, sampling techniques, and quality assurance/quality control(QA/QC) essential to acquire quality environmental data
  • A detailed discussion of: the theories of absorptionspectroscopy for qualitative and quantitative environmentalanalysis; metal analysis using various atomic absorption andemission spectrometric methods; and the instrumental principles ofcommon chromatographic and electrochemical methods
  • An introduction to advanced analytical techniques, includingvarious hyphenated mass spectrometries and nuclear magneticresonance spectroscopy

With real-life case studies that illustrate the principles plusproblems and questions at the end of each chapter to solidifyunderstanding, this is a practical, hands-on reference forpractitioners and a great textbook for upper-level undergraduatesand graduate students in environmental science and engineering.

What People are Saying About This

From the Publisher

"This book gives an excellent contribution to the understanding of the fundamentals of environmental sampling and analysis including. The book is a unique reference for a large audience from students to environmental scientists at different stage of their work. The book is a valuable guide and reference tool and should appeal to a wide ranging audience including students, academics and environmental professionals" (Environment International, 2008)

"As a particular feature, it includes questions and exercise problems in each chapter to help to understand these concepts." (International Journal of Environmental and Analytical Chemistry, December 2007)

"The author writes in the first person plural which gives the book a rather chatty style that works reasonably well. References to real-life case studies also helps put the material in context and some chapters have a 'practical tips' section which is a useful feature" (Chemistry World, September 2007)

"An excellent book that I am sure will be adopted by many faculty members." (Journal of Hazardous Materials, August 17, 2007)
