This book was released on 2013-11-11 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past ten years a variety of methods involving mass spectrom etry have been developed for the analysis of environmentally important compounds. Much has been accomplished in that period to solve some of the important problems in the field. Growth of this methodology and its accomplishments has reached the point where an individual scientist can no longer have an in-depth knowledge of all the areas involved. We have attempted to provide this in-depth picture to those scientists con cerned by having the important topics treated by experts in the subject matter. In order to provide all the relevant material in one volume we begin with the general topics which provide the basic background material necessary to understand the techniques discussed in the in-depth topics. These general chapters are kept brief, containing only the essentials needed by the working scientist to deal with the practical applications. References in these chapters are chosen to permit a more complete study of each chapter. The concept for this book was developed during the activities of two of the editors under a NATO travel grant. These editors gratefully acknowledge this support which made the initial planning of this book possible. The editors would like to thank the individual authors of each chap ter for their cooperation and generously giving of their time for this project.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This detailed handbook covers different chromatographic analysis techniques and chromatographic data for compounds found in air, water, and soil, and sludge. The new edition outlines developments relevant to environmental analysis, especially when using chromatographic mass spectrometric techniques. It addresses new issues, new lines of discussion, and new findings, and develops in greater detail the aspects related to chromatographic analysis in the environment. It also includes different analytical methodologies, addresses instrumental aspects, and outlines conclusions and perspectives for the future.

Download or read book Mobile Field Monitoring of Volatile Organics and Toxic Air Pollutants Using a Mobile Tandem Mass Spectrometer System written by BI. Shushan and published by . This book was released on 1990 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent marriage of tandem mass spectrometry (MS/MS) to mobile trace atmospheric gas analyzer (TAGA) technology has resulted in an analytical system capable of real-time direct air analysis for toxic air pollutants (TAP), volatile organic compounds (VOC), and odor compounds at concentrations as low as a few parts per trillion. This direct analytical approach obviates problems associated with conventional trapping methods. The latest design of a mobile MS/MS laboratory comprises a customized 9-m (30-ft) transit motor coach configured with a TAGA 6000EM MS/MS system and ancillary equipment. This paper discusses the incorporation of a sorbent cartridge purge unit into the TAGA system to assist in rapidly distinguishing between isomeric compounds (for example, ethylbenzene and xylene) using gas chromatography (GC/MS/MS. This paper also describes combining real-time TAP analysis with meteorological data to rapidly and accurately characterize plume profiles and emission frequencies. The mobility of the TAGA detector permitted the precise location of point source and fugitive emissions. Examples are provided for industrial emissions of methyl ethyl ketone and dimethyl sulfide. A simple method of on-site calibration was used, based upon headspace syringe injection. Under interactive computer control, calibration constants were determined in about 5 min per compound within the ambient air matrix. Other recent software developments are discussed, including the ability to simultaneously monitor up to 128 different compounds with real-time output in concentration units.
Download or read book Characterization of Particulate Pollution by Aerosol Mass Spectrometry written by Courtney Leigh Herring and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric aerosols impact human health, climate, and air pollution and arrive in the atmosphere by countless number of sources. One of the largest uncertainties in understanding these impacts is due to limitations in our understanding of the organic aerosol (OA) components. To understand this complex mixture of thousands of compounds accurate high-resolution chemical speciation is needed. An Aerodyne High Resolution Time of Flight Aerosol Mass Spectrometer (HR-ToF-AMS or HR-AMS) was deployed in two separate month-long studies to measure atmospheric particulate pollution. The first study, at the Lovelace Respiratory Research Institute (LRRI), focused on the measurement of gasoline and diesel engine exhaust under various loads and dilutions in controlled chamber experiments. HR-AMS data demonstrated clean signal associated with 53 polycyclic aromatic hydrocarbon (PAH) compounds. PAHs are of interest due to their carcinogenic implication and negative health effects especially when associated with submicron particles. From this work a novel methodology was developed for quantifying these compounds by their molecular ion signal (P-MIP). In the second study, conducted in Yakima, WA, ambient wintertime pollution was characterized and the OA components were deconvolved using positive matrix factorization (PMF). This investigation resulted in the identification of two new amine associated factors which were identified by mass spectra peaks from six dominant amine ions (C3H8N+, C2H6N2+, C4H 10N+, C3H8N2 +, C5H12N+, and C6H 14N+). Amine ions are of interest to atmospheric research because of their implications on climate and formation of new particles. The unifying implication from both studies was the utilization of the HR-AMS to identify atmospheric pollutants that continue to generate ongoing research interests (due to their impacts on climate, pollution, or human health) and are typically difficult to measure by the HR-AMS. Additionally, included in this dissertation are four examples of science/engineering related inquiry-based lessons that were developed to relate well with my own Master's research field and implemented into three high school science and math classrooms over the course of a two year NSF STEM Fellowship. Lastly, a two-year long case study following qualitative and quantitative data from 296 students one of these activities provides examples of the positive impact by these types of developed activities.
