Air pollution determination is one of the most important fields of gas chromatography application in practice. This book provides a systematic description of the main stages of air pollution determination, ranging from sampling problems to the quantitative estimation of the acquired data. Special attention is paid to the problem of gas, vapor, spray and solid particles extraction from air. The main methods of sampling procedure, namely, container utilization, cryogenic concentration, absorption, adsorption, chemisorption and filter usage, and successive impurities extraction are also handled. Sorption theory and the problems of sorption and desorption efficiency for hazardous impurities being extracted from traps with sorbents are discussed in detail. The practical utilization of different sorbents (silica, activated carbon, polymers etc.) to carry out sampling procedures for 200 main pollutants with known TLV (USSR and USA) is also considered. This highly informative book, reflecting several insufficiently known techniques as well as the experience of both western and Soviet researchers, should be of interest to both beginners and skilled researchers.
Gas chromatography mass spectrometry (GC-MS) has been the technique of choice of analytical scientists for many years. The latest developments in instrumentation, including tandem mass spectrometry (MS-MS) and time-of-flight (TOF) detectors, have opened up and broadened the scope of environmental analytical chemistry. This book summarizes the major advances and relevant applications of GC-MS techniques over the last 10 years, with chapters by leading authors in the field of environmental chemistry. The authors are drawn from academia, industry and government. The book is organized in three main parts. Part I covers applications of basic GC-MS to solve environmental-related problems. Part II focuses on GC-MS-MS instrumentation for the analyses of a broad range of analysis in environmental samples (pesticides, persistent organic pollutants, endocrine disruptors, etc.). Part III covers the use of more advanced GC-MS techniques using low- and high-resolution mass spectrometry for many applications related to the environment, food and industry. - Summarizes the major advances of GC-MS techniques in the last decade - Presents relevant applications of GC-MS techniques - Covers academic, industrial and governmental sectors
Modern Environmental Analysis Techniques for Pollutants presents established environmental analysis methods, rapidly emerging technologies, and potential future research directions. As methods of environmental analysis move toward lower impact, lower cost, miniaturization, automation, and simplicity, new methods emerge and ultimately improve the accuracy of their analytical results. This book gives in-depth, step-by-step descriptions of a variety of techniques, including methods used in sampling, field sample handling, sample preparation, quantification, and statistical evaluation. Modern Environmental Analysis Techniques for Pollutants aims to deliver a comprehensive and easy-to-read text for students and researchers in the environmental analysis arena and to provide essential information to consultants and regulators about analytical and quality control procedures helpful in their evaluation and decision-making procedures. - Bridges the gap in current literature on analytical chemistry techniques and their application to environmental analysis - Covers the use of nanomaterials in environmental analysis, as well as the monitoring and analysis of nanomaterials in the environment - Looks to the past, present and future of environmental analysis, with chapters on historical background, established and emerging techniques and instrumentation, and predictions
This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
The study of fire debris analysis is vital to the function of all fire investigations, and, as such, Fire Debris Analysis is an essential resource for fire investigators. The present methods of analysis include the use of gas chromatography and gas chromatography-mass spectrometry, techniques which are well established and used by crime laboratories throughout the world. However, despite their universality, this is the first comprehensive resource that addresses their application to fire debris analysis.Fire Debris Analysis covers topics such as the physics and chemistry of fire and liquid fuels, the interpretation of data obtained from fire debris, and the future of the subject. Its cutting-edge material and experienced author team distinguishes this book as a quality reference that should be on the shelves of all crime laboratories. - Serves as a comprehensive guide to the science of fire debris analysis - Presents both basic and advanced concepts in an easily readable, logical sequence - Includes a full-color insert with figures that illustrate key concepts discussed in the text
Gas chromatography continues to be one of the most widely used analytical techniques, since its applications today expand into fields such as biomarker research or metabolomics. This new practical textbook enables the reader to make full use of gas chromatography. Essential fundamentals and their implications for the practical work at the instrument are provided, as well as details on the instrumentation such as inlet systems, columns and detectors. Specialized techniques from all aspects of GC are introduced ranging from sample preparation, solvent-free injection techniques, and pyrolysis GC, to separation including fast GC and comprehensive GCxGC and finally detection, such as GC-MS and element-specific detection. Various fields of application such as enantiomer, food, flavor and fragrance analysis, physicochemical measurements, forensic toxicology, and clinical analysis are discussed as well as cutting-edge application in metabolomics is covered.
With an emphasis on passive sampling, this volume focuses on the environmental monitoring for common gaseous pollutants. It offers an overview of the history and nature of pollutants of concern to museums and the challenges facing scientists, conservators, and managers seeking to develop target pollutant guidelines to protect cultural property.
