Book Synopsis The Geochemistry of Stable Chlorine and Bromine Isotopes by : Hans Eggenkamp
Download or read book The Geochemistry of Stable Chlorine and Bromine Isotopes written by Hans Eggenkamp and published by Springer. This book was released on 2014-08-25 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides detailed information on the history, analysis and applications of chlorine and bromine isotope geochemistry. Chlorine and bromine are geochemically unique as they prefer to exist as single charged negative ions. For this reason isotope fractionation reflects mostly processes that are not related to changes in the redox state and this fractionation is generally modest. The book will describe the processes that are most easily detected using these isotopes. Also isotope variations, and processes that cause them, measured in oxidised species such as perchlorates and in organic molecules will be described in this book.

Available in PDF, EPUB and Kindle. Book excerpt: "The geochemistry of chlorine isotopes" describes Hans Eggenkamp's studies to obtain his PhD degree at Utrecht University. It describes methods to measure stable chlorine isotope variations in different types of natural samples, theoretical fractionation as the result of diffusion and about ten case studies showing chlorine isotope fractionation in natural systems. In these case studies it was discovered that chlorine stable isotopes fractionate only little, although systematically, in processes such as salt precipitation and diffusion. Variations found in natural samples reflect as such in most cases processes that take place within (larger) reservoirs. The main purpose of the project was to develop procedures to measure stable chlorine isotope compositions in different sample types and to study variations therein. The study gives a good overview of the knowledge on stable chlorine isotope geochemistry at the moment of its original publication in 1994.

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chlorinated ethenes are among the most frequently detected groundwater contaminants in industrially developed countries. Although their degradation pathways have been understood, assessing the progress of natural attenuation of chlorinated ethenes still remains a challenge. This thesis explored the possibilities and limits of the use of compound-specific stable isotope analysis as a field investigation tool to document and to quantify the progress of natural attenuation of chlorinated ethenes. The thesis focused particularly on the fate of reductive dechlorination intermediates such as cis-dichloroethene (cDCE) and vinyl chloride (VC) as the success of natural attenuation of chlorinated ethenes depends principally on the fate of these compounds. Two field investigations were carried out to demonstrate the use of stable isotope analysis to characterize the progress of natural attenuation of chlorinated ethenes. One site was characterized as a complex hydrological and geochemical system at the groundwater-surface water interface where a tetrachloroethene- (PCE) plume discharged through the streambed. Another site was located under relatively stable hydrological conditions and characterized by a 2-km long plume of chlorinated ethenes. Laboratory studies evaluated the use of combined carbon and chlorine isotope analysis to distinguish different degradation pathways of cDCE and VC, and the same approach was employed at a field site to determine the fate of cDCE. Numerical studies evaluated the field applicability of isotope-based quantification, according to the Rayleigh isotope fractionation model, to estimate the extent of degradation and the first-order reaction rate under various flow conditions. In addition, a scheme to quantify the reductive dechlorination rates of chlorinated ethenes based on field concentration and isotope data at one of the field sites was proposed and evaluated with a series of 3D analytical solutions to accommodate sequential reactions. The stu.

Book Synopsis Groundwater Geochemistry and Isotopes by : Ian Clark
Download or read book Groundwater Geochemistry and Isotopes written by Ian Clark and published by CRC Press. This book was released on 2015-04-17 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: There remains a lack of understanding of environmental isotopes and their use; students and practitioners typically find the concepts of isotope concentrations and partitioning to be more complicated than for geochemistry. However, this need not be so, if the basics are presented together with geochemistry, using case studies and examples to make the point. This new book presents the basics of environmental isotopes and geochemistry together, with case studies and simple examples that build a real understanding of their use in natural and contaminated groundwater.

Download or read book Application of Environmental Isotope Methods for Groundwater Studies in the ESCWA Region (Economic and Social Commission for Western Asia) written by Wolfgang Wagner and published by Bundesanstalt Fur Geowissenschaften Und Rohstoffe. This book was released on 1999 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous hydrological projects have been carried out using isotopic methods over the last two decades in the ESCWA region, which includes the Arabian Peninsula, the Arabian countries to the north, and Egypt. The large amount of data obtained from groundwater samples has been evaluated together with the hydrogeological, hydrochemical and water management data available for the area. Analyses of the stable isotopes of oxygen, hydrogen, and carbon in the groundwater samples, as well as the naturally occurring radioactive isotopes of hydrogen and carbon are used for the localization of groundwater recharge areas; determination and quantification of mixtures of groundwater from different sources; reconstruction of groundwater flow systems on regional and local scales; determination of the paleoclimatic effects on the geohydraulic conditions; determination of groundwater ages, i.e., residence times; and distinguishing between renewable and fossil groundwater resources. Extensive hydrological studies using isotopic methods have been conducted in the ESCWA region on the following aquifer systems and topics: isotopic composition of precipitation in Jordan and Syria; groundwater turnover in karst aquifers in the highlands of western Jordan, the mountains in western Syria and the West Bank; groundwater recharge from precipitation and surface water on the Damascus plain; origin and age of groundwater in the basalt aquifer system in Jordan and Syria; recently recharged freshwater lenses and fossil groundwater in Badiye and Hamad (steppe and desert regions in Syria and eastern Jordan and the adjacent areas in Iraq and Saudi Arabia); low of fossil groundwater and local, recently recharged groundwater in Paleogene carbonate aquifers in eastern Saudi Arabia, the Golf region, and southern Oman; groundwater recharge from flash floods in the aquifers in unconsolidated rock in wadis and coastal plains of the Arabian Peninsula; age and origin of groundwater in aquifers in consolidated rock in the mountains of Oman. The discussion of the hydrogeological significance of isotope data is supplemented by comments on the most important current hydrogeological problems in the ESCWA region that could be investigated using isotopic methods. These include problems of groundwater recharge, the provenance of groundwater, groundwater flow systems on regional and local scales, paleohydrological conditions, and groundwater quality, particularly contamination by human activities. All available publications on the isotope hydrology of the ESCWA region are listed in the bibliography, as well as basic publications on isotope hydrology in arid regions.

Book Synopsis Encyclopedia of Geochemistry by : William M. White
Download or read book Encyclopedia of Geochemistry written by William M. White and published by Springer. This book was released on 2018-07-24 with total page 1680 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia is a complete and authoritative reference work for this rapidly evolving field. Over 200 international scientists, each experts in their specialties, have written over 330 separate topics on different aspects of geochemistry including geochemical thermodynamics and kinetics, isotope and organic geochemistry, meteorites and cosmochemistry, the carbon cycle and climate, trace elements, geochemistry of high and low temperature processes, and ore deposition, to name just a few. The geochemical behavior of the elements is described as is the state of the art in analytical geochemistry. Each topic incorporates cross-referencing to related articles, and also has its own reference list to lead the reader to the essential articles within the published literature. The entries are arranged alphabetically, for easy access, and the subject and citation indices are comprehensive and extensive. Geochemistry applies chemical techniques and approaches to understanding the Earth and how it works. It touches upon almost every aspect of earth science, ranging from applied topics such as the search for energy and mineral resources, environmental pollution, and climate change to more basic questions such as the Earth’s origin and composition, the origin and evolution of life, rock weathering and metamorphism, and the pattern of ocean and mantle circulation. Geochemistry allows us to assign absolute ages to events in Earth’s history, to trace the flow of ocean water both now and in the past, trace sediments into subduction zones and arc volcanoes, and trace petroleum to its source rock and ultimately the environment in which it formed. The earliest of evidence of life is chemical and isotopic traces, not fossils, preserved in rocks. Geochemistry has allowed us to unravel the history of the ice ages and thereby deduce their cause. Geochemistry allows us to determine the swings in Earth’s surface temperatures during the ice ages, determine the temperatures and pressures at which rocks have been metamorphosed, and the rates at which ancient magma chambers cooled and crystallized. The field has grown rapidly more sophisticated, in both analytical techniques that can determine elemental concentrations or isotope ratios with exquisite precision and in computational modeling on scales ranging from atomic to planetary.
