Beschreibungen

<p><b>The most comprehensive and up-to-date volume on environmental analysis available today, this is the standard laboratory reference for any environmental or chemical engineer, chemist, or scientist.</b></p> <p>Today, environmental issues are a great cause of concern at the global level, and universities and other institutions around the world are involved in research on climate change, deforestation, pollution control, and many other issues. Moreover, environmental science and environmental biotechnology are inherent parts of various courses while some universities provide degrees in these fields. Although the environment perspective of water is discussed time and again in research, academic, and non-academic discussions, there is no book summarizing protocols involved in water quality analysis. The information seems to be sporadically distributed on the internet.</p> <p>Even if available at all, the information does not discuss limits of the protocols or caveats involved. For example, essays on chemical oxygen demand (COD) on the internet mostly do not discuss differences between organic compounds of biological origin and aliphatic/aromatic. The authors have performed nearly all the protocols mentioned in this new volume, and their protocols are discussed in a simplified, easy-to-understand manner. The book has been written after elaborative discussions with and input from faculty and research students to ensure the clarity of the material for use on many levels.</p> <p>Further, the authors have emphasized low-cost methods which involve minimal use of high-end instrumentation keeping in mind limitations faced in developing countries. A valuable reference for engineers, scientists, chemists, and students, this volume is applicable to many different fields, across many different industries, at all levels. It is a must-have for any library.</p>

<p><b>Anshul Nigam, PhD,</b> has completed his Masters and PhD from IIT Kanpur and IIT Bombay, respectively. He is the recipient of prestigious GATE, DBT and NDF fellowships in India and has eight years of experience in both academia and industry. He is currently associated with Amity University of Maharashtra as senior assistant professor and has received grants from industry for various projects. He has several publications in a variety of topics ranging from drug discovery to bioremediation. <p><b>Rupal Gupta</b> is a graduate student at Amity Institute of Biotechnology, Amity University Mumbai. She received an internship in biotech and environmental start-ups and has presented her work in various national and international conferences.
<p><b>The most comprehensive and up-to-date volume on environmental analysis available today, this is the standard laboratory reference for any environmental or chemical engineer, chemist, or scientist.</b> <p>Today, environmental issues are a great cause of concern at the global level, and universities and other institutions around the world are involved in research on climate change, deforestation, pollution control, and many other issues. Moreover, environmental science and environmental biotechnology are inherent parts of various courses while some universities provide degrees in these fields. Although the environment perspective of water is discussed time and again in research, academic, and non-academic discussions, there is no book summarizing protocols involved in water quality analysis. The information seems to be sporadically distributed on the internet. <p>Even if available at all, the information does not discuss limits of the protocols or caveats involved. For example, essays on chemical oxygen demand (COD) on the internet mostly do not discuss differences between organic compounds of biological origin and aliphatic/aromatic. The authors have performed nearly all the protocols mentioned in this new volume, and their protocols are discussed in a simplified, easy-to-understand manner. The book has been written after elaborative discussions with and input from faculty and research students to ensure the clarity of the material for use on many levels. <p>Further, the authors have emphasized low-cost methods which involve minimal use of high-end instrumentation keeping in mind limitations faced in developing countries. A valuable reference for engineers, scientists, chemists, and students, this volume is applicable to many different fields, across many different industries, at all levels. It is a must-have for any library. <p><b>This fascinating new volume from Wiley-Scrivener:</b> <ul> <li>Offers a thorough, comprehensive reference for anyone working in environmental analysis, for engineers, scientists, chemists, and students in many fields</li> <li>Analyzes in detail a wide spectrum of air, soil, and water in an easy-to-understand laboratory reference</li> <li>Outlines the practical applications of environmental analysis across many different industries and fields</li> <li>Includes coverage of the entire spectrum of environmental analysis with minimal instrumentation in one volume</li> <li>Covers low-cost methods of environmental analysis</li> </ul>
