Produktbeschreibung

Fundamentals of Environmental Sampling and Analysis A fully reworked and updated introduction to the fundamentals and applications of environmental sampling and analysis Environmental sampling and analysis are essential components of environmental data acquisition and scientific research. The acquisition of reliable data with respect to proper sampling, chemical and instrumental methodology, and QA/QC is a critical precursor to all environmental work. No would-be environmental scientist, engineer, or policymaker can succeed without an understanding of how to correctly acquire, assess and use credible data. Fundamentals of Environmental Sampling and Analysis, 2nd edition provides this understanding, with a comprehensive survey of the theory and applications of these critical sampling and analytical tools. The field of environmental research has expanded greatly since the publication of the first edition, and this book has been completely rewritten to reflect the latest studies and technological developments. The resulting mix of theory and practice will continue to serve as the standard introduction to the subject. Readers of the second edition of Fundamentals of Environmental Sampling and Analysis will also find: * Three new chapters and numerous expanded sections on topics of emerging environmental concerns * Detailed discussion of subjects including passive sampling, Raman spectroscopy, non-targeted mass spectroscopic analysis, and many more * Over 500 sample problems and solutions along with other supplementary instructional materials Fundamentals of Environmental Sampling and Analysis is ideal for students of environmental science and engineering as well as professionals and regulators for whom reliable environmental data through sampling and analysis is critical.
