In environmental laboratory analysis, quality issues related to the taking and handling of samples are commonly unrecognized, underestimated, or ignored by the professionals involved in the chain of data acquisition, analysis and use. The ten chapters of this book provide comprehensive coverage of quality issues in environmental sampling, addressing recent developments and research advances together with advice based on the contributing experts’ practical experience. Each chapter includes a literature review and, where appropriate, a case study relevant to the topic. The book will be of value to those new to sampling as well as to those who are more experienced but who may face challenges under various scenarios of environmental, resource, and budgetary constraints. The book will be suitable to students in environmental studies as well as practitioners, such as field personnel, project managers, data users, and decision-makers.
