This book introduces a comprehensive overview on the fundamentals and applications of environmental sampling and analysis for students in environmental science and engineering as well as environmental professionals involved in sampling and analytical work. The book details fundamentals of sampling, selection of standard methods, QA/QC, sample preparation, chemical and instrumental principles, and method applications to various contaminants in environmental matrices (air, water, soil, waste, and biological samples). The book gives an integrated introduction to sampling and analysis – both are essential to quality environmental data. For example, contrary to other books that introduce a specific area of sampling and analysis, this text provides a balanced mix of field sampling and laboratory analysis, essential knowledge in chemistry/statistics/hydrology/regulations, wet chemical methods for conventional chemicals as well as various modern instrumental techniques for contaminants of emerging concerns. The new edition adds three standalone chapters regarding the basics of analytical and organic chemistry, environmental data analysis, mass spectrometry and other significant amounts of new materials such as time-integrated passive sampling, incremental sampling, green sample preparation, Raman spectroscopy, chiral separation, and non-target analysis. In addition, the second edition provides more examples, visual aids, case studies, and end-of-chapter exercise problems to enhance a better understanding of the fundamentals of environmental sampling and analysis while incorporating current literature (mostly peer-reviewed journal papers) regarding the applications and challenges in the field of environmental sampling and analysis.
