Book Synopsis Mass Spectrometry of Priority Pollutants by : Brian Middleditch
Download or read book Mass Spectrometry of Priority Pollutants written by Brian Middleditch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the list of organic priority pollutants was first published, many mass spec troscopists went scrambling to their reference books. GC-MS was mandated for the analysis of 114 compounds, yet the spectra of many of them, if they had been recorded at all, were scattered throughout the literature. Moreover, it soon became apparent that, even if a sufficient number of instruments could be made available to undertake the task of monitoring 114 substances in the effluents of 21 categories of industry, the personnel could not be trained to perform the analyses and interpret the results. The solution to this problem has been the development of highly automated mass spectrometers which can be operated by personnel without the traditional research training. This book is for the new breed of mass spectroscopist who is not interested in the esoteric details of mass spectral fragmentation, but who merely wishes to identify specific pollutants in effluents. Our inclusion of com prehensive lists of synonyms and bibliographic data should make the book of even greater value to the reader who is not too familiar with the idiosyncrasies of chemical nomenclature and the scientific literature. The experienced mass spectroscopist should also benefit from having all of the data collected together in one volume. This is a book to be used, rather than deposited in a library distant from the laboratory: we would hope that it will fmd a place on top of every mass spectrometer used for the analysis of priority pollutants.

Book Synopsis Mass Spectrometry in Environmental Analysis by : Valeria Severino
Download or read book Mass Spectrometry in Environmental Analysis written by Valeria Severino and published by Arcler Press. This book was released on 2017-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of pollutants in the environment is a matter of debate since longtime. People are always more aware of the problem that is mainly related to anthropogenic compounds, and analytical methods able to detect low-amount pollutants are required. These compounds are strictly regulated by worldwide legislations aimed to develop accurate environmental risk assessment. Overall, environmental analysis is aimed to monitor and detect levels of contaminants in the water, atmosphere, soils, and other environmental conditions. One of the main challenges in this kind of analysis relies on the extreme complexity and variability of the sample to be analyzed. Compounds of interest, in fact, can be present in various matrices deeply variable according to the origin of collected samples. Indeed, a reliable and versatile analytical approach is necessary to overcome these challenging problems.Mass spectrometry (MS) is a wide used analytical technique in which ionized chemical species are sorted on the basis of their mass-to-charge ratio (m/z). MS is commonly used with qualitative and quantitative purposes, representing a high-performances instrument to be used in several fields. Moreover, mass spectrometers can be easily coupled to gas chromatography (GC) and liquid chromatography (LC), thus resulting in an excellent sensitive and selective tool to perform environmental analysis. Currently, MS-based methods are commonly used for environmental analyses allowing an accurate and reproducible identification and quantitation of a huge variety of pollutants, even in low amounts. This book covers several MS-based approaches for environmental analysis, illustrating a first overview of commonly used platforms followed by some interesting examples of applications. The Section 1 reports current trends in environmental analysis, highlighting the state-of-the-art of international legislations and future perspectives. The Section 2 is an overview of MS-based methods and platforms currently used for environmental analysis. MS-based metabolomics, lipidomics and other classical approaches, along with their features and limitations, are described. Moreover, some specific techniques such as the targeted parallel reaction monitoring, are included. Finally, the Section 3 contains recent and innovative applications of MS-based methods for environmental analysis. Among others, MS-based approaches have been used for the multiple screening of 90 emerging contaminants in liquid and solid environmental matrices, and for the detection of pollutants as alkanolamines, thallium and pesticides.
Book Synopsis Gas Chromatography Mass Spectrometry Applications in Microbiology by : Goran Odham
Download or read book Gas Chromatography Mass Spectrometry Applications in Microbiology written by Goran Odham and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: During recent years there has been increasing interest in the value of a number of chemical and physical-chemical analytical methods for the detection and characterization of microorganisms. Furthermore, such methods are currently used in studies on microbial metabolic processes, on the role of microorganisms in the turnover of inorganic and organic compounds, and on the impact on environmental changes by microbial activity. Moreover, the introduction of some of these methods not only shortens the analytical time period compared to ·'traditional" techniques, but also improves the analytical quality. Mass spectrometry (MS) combined with chromatographic inlet systems, particularly gas chromatography (GC), belongs to those methods which during recent years have established their value for the above-mentioned purposes. The present volume starts with basic chapters on the principles for MS and common inlet systems, particulary Gc. It discusses applications of these techniques to a number of microbiological disciplines, e.g., ecologi cal and medical microbiology. Emphasis is laid on organic compound classes vii viii / PREFACE of special relevance to microbiology, e.g., volatiles, lipids, amino acids, peptides and carbohydrates. Some compound classes of a more general biochemical rather than specific microbiological importance, e.g., steroids and nucleotides, are dealt with briefly. The editors wish to thank all those who have contributed to this book. We hope it will stimulate further research in this futuristic field and will be of practical value.
Book Synopsis The Evaluation of Environmental Contaminants Using Static Headspace Gas Chromatography Mass Spectrometry, Vacuum Ultraviolet Detection and Ionic Liquids by : Emmanuel Varona -Torres
Download or read book The Evaluation of Environmental Contaminants Using Static Headspace Gas Chromatography Mass Spectrometry, Vacuum Ultraviolet Detection and Ionic Liquids written by Emmanuel Varona -Torres and published by . This book was released on 2021 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: In analytical chemistry the term "headspace" refers to the vapor that forms above a sample (liquid or solid) in a closed container. Headspace (HS) sampling is the method to promote partition between volatile components from the sample matrix and then analyzed by gas chromatography (GC). HS is an excellent technique to introduce a"clean" vapor sample into the GC and avoids introduction of non-volatile components from the sample matrix and often used for determination of volatile organic compounds (VOCs) with minimal or no additional sample preparation. Concerns about the environmental impact of fossil fuel extraction techniques (i.e.,hydraulic fracturing and other well stimulation techniques) have risen due to its expansion in the United States and other countries. Robust atmospheric studies have attributed to the emissions of rogue greenhouse gases and VOCs to mechanical inefficiencies commonly found in the midstream production process, such as gas flaring stations, condensate tanks, and pipelines. However, the interplay between fossil fuel extraction activities and soil quality has not received much attention. Utilizing headspace gas chromatography mass spectrometry (HS-GC-MS) and an establish standard method by the Environmental Protection Agency (EPA), we present a study of soil near oil and gas production in verified emissions of volatile contaminants. The findings provide an initial indication of the interactions between atmospheric VOCs contamination events and the accumulation of those contaminants in soil where, varying soil texture was found to contribute to total amount detected. Room temperature ionic liquids (RTILs) have received significant attention in HS analysis due to their unique physiochemical properties (i.e., negligible vapor pressures, tunable thermal stabilities, tunable viscosities and wide liquid range). RTILs are salts in which ions are poorly coordinated, resulting in a liquid state at room temperature. The evaluation of RTILs as co-solvent in soil analysis, in an effort to increase sensitivity, reduce and normalized the matrix-effects associated with varying soil compositions. It was found that hydrophilic RTILs investigated, 1-ethyl-3-methylimidazolium ethylsulfate ([EMIM][ESO4]), 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM][DEP]), tris(2-hydroxyethyl)methylammonium methylsulfate ([MTEOA][MeOSO3]), reduced matrix-effect from varying soil composition thus, reducing the need to characterized and matrix-match soil textures for calibration purposes. It also reduced the analysis time and increased precision and accuracy for the quantification of VOCs in variable soil matrices relative to standard methods. Understanding the thermodynamic interactions between an analyte and the sample phase is of paramount importance when eliciting a co-solvent in HS analysis. The partition coefficient (KP) is an equilibrium constant that describes the distribution of the analyte between two phases (i.e., sample phase/ gas phase). Kp determinations by HSGC is acquired by two methods: vapor phase calibration (VPC) and phase ratio variation (PRV). Kp determinations of analytes in HS co-solvents can help guide the analyst in which to use for the analysis at hand. Here we demonstrate the ability of using a pressurized - loop HS system in conjunction with gas chromatography vacuum ultraviolet detection (HS-GC-VUV) to directly calculate the concentration of the analyte in the gas phase, by pseudo-absolute quantification (PAQ), thus allowing for quick determination of Kp and other thermodynamic properties such as enthalpy ( ∆H )and entropy (∆S ) of the system. The Kp determinations by PAQ were comparable to those obtained using theVP C method, with differences in the average values ranging

Book Synopsis Sample Handling and Trace Analysis of Pollutants by : Damià Barceló
Download or read book Sample Handling and Trace Analysis of Pollutants written by Damià Barceló and published by Elsevier Science Limited. This book was released on 2000 with total page 1138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an updated, completely revised version of a previous volume in this series entitled: ENVIRONMENTAL ANALYSIS -- Techniques, applications and quality assurance. The book treats different aspects of environmental analysis such as sample handling and analytical techniques, the applications to trace analysis of pollutants (mainly organic compounds), and quality assurance aspects, including the use of certified reference materials for the quality control of the whole analytical process. New analytical techniques are presented that have been developed significantly over the last 6 years, like solid phase microextraction, microwave-assisted extraction, liquid chromatography-mass spectrometric methods, immunoassays, and biosensors. The book is divided into four sections. The first describes field sampling techniques and sample preparation in environmental matrices: water, soil, sediment and biota. The second section covers the application areas which are either based on techniques, like the use of gas chromatography-atomic emission detection, immunoassays, or coupled-column liquid chromatography, or on specific application areas, like chlorinated compounds, pesticides, phenols, mycotoxins, phytotoxins, radionuclides, industrial effluents and wastes, including mine waste. Validation and quality assurance are described in the third section, together with the interpretation of environmental data using advanced chemometric techniques. The final section reports the use of somewhat advanced analytical methods, usually more expensive, less routinely used or less developed, for the determination of pollutants.

Book Synopsis Persistent Organic Pollutants in Human Milk by : Rainer Malisch
Download or read book Persistent Organic Pollutants in Human Milk written by Rainer Malisch and published by Springer Nature. This book was released on 2023-11-12 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the trends of persistent organic pollutants (POPs) in human milk and discusses the main findings of five global surveys that were coordinated by the World Health Organization (WHO) and the United Nations Environment Programme (UNEP) from 2000 to 2019. Human milk was selected as core matrix for human exposure under the Global Monitoring Plan for effectiveness evaluation of the Stockholm Convention on Persistent Organic Pollutants. Milk from well-defined groups of mothers was collected and mixed to form a representative sample per country. Datasets collected represent the largest global human tissues survey with a harmonized protocol, carried out in a uniform format for more than two decades. Altogether 69 countries participated in these studies between 2000 and 2015, and more than 40 countries participated in the study from 2016 to 2019. Divided into 5 parts, the book offers an authoritative overview of human milk biomonitoring; collates the harmonized sampling requirements and analytical methods for the identification and quantification of contaminants in human milk; examines the results of the WHO/UNEP-coordinated exposure studies, including the identification of selected chlorinated pesticides, dioxin-like compounds, industrial chemicals like polychlorinated biphenyls (PCB) and chlorinated paraffins, polybrominated POPs and PFAS, among others; and traces geographic, temporal and cross-substance trends and correlations, and human health risks. The book finishes by providing the reader with the summary of the main findings and outlook from these studies, in which the comparison of concentrations found for the wide range of POPs listed in the Stockholm Convention allowed the identification of possible needs for actions and follow-ups in different countries/regions. This book contributes to the understanding of exposure to hazardous chemicals and pollution as addressed by the UN Sustainable Development Goals on Good Health and Well-being (SDG 3) and will appeal to environmental and analytical chemists, researchers, professionals, and policymakers interested in learning more about contaminants in human milk. Given its breadth, this book will also appeal to a broader audience interested in maternal and child health.
