This concise book covers all the critical aspects of environmental sampling and analysis. Extensively peer-reviewed by scientists from the U.S. Environmental Protection Agency and other government agencies, industry and academia, it is packed with practical advice and tips from renowned experts.
Planning, sampling, analysis, QA/QC, and reporting are discussed for air, water, solid liquid, and biological samples, with emphasis on the interdependence between sampling and analytical activities. Special requirements for sampling devices, containers, and preservatives are provided with convenient checklists for sampling plans and protocols.
New and revised recommendations involving method detection levels, reliable detection levels, and levels of quantitation are discussed in conjunction with laboratory reports and user presentations of data near analytical detection limits.
This is a valuable and comprehensive reference book for chemists, technicians, consultants, lawyers, regulators, engineers, quality control officers, news and information managers, teachers, and students.
