Download or read book Trace Element Speciation for Environment Food and Health written by L. Ebdon and published by Royal Society of Chemistry. This book was released on 2001 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing progress of science has shown that it is important for analytical scientists to determine not only the presence of particular elements, but also their species. There are many fields where this is applicable, and where there are a number of topics to be addressed. Developing separation and measurement systems for the many element species has tested the resourcefulness of analytical chemists over recent decades. A product of the EU sponsored Speciation 21 Network, this book presents a detailed review of the state-of-the-art of speciation issues in the occupational health, food and environment sectors, along with the main conclusions arising from discussions held during expert meetings. Topics covered include mercury and organotin compounds in the environment; factors affecting the health of workers; the importance of speciation of trace elements for health, and subsequent metabolism in the body; analytical methodologies; risk assessment; and legislation. Trace Element Speciation for Environment, Food and Health provides an insight into applied research in the speciation field and how it has become so important in all the fields represented. With its comprehensive coverage, it will be of particular interest to researchers in industry and academia, as well as government agencies and legislative bodies.

This book was released on 2007 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elemental analysis using ICP-MS and speciation analysis can be used in complement to confirm species recovery and mass balance. When speciation information using HPLC/GC-ICP-MS does not provide enough information, molecular mass spectrometry techniques with softer ionization techniques (able to preserve structural characteristics) can enable confident identification of a given species.

Download or read book Treatise on Geochemistry written by and published by Newnes. This book was released on 2013-10-19 with total page 14787 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!
Download or read book Hydrogeochemistry of Aquatic Ecosystems written by Sughosh Madhav and published by John Wiley & Sons. This book was released on 2022-11-30 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogeochemistry of Aquatic Ecosystems Discover the geological foundation of global water supply, focusing on resource conservation and restoration Hydrogeochemistry explores the connections between the geology of a region and the chemical characteristics and quality of its water sources, including such factors as erosion, evaporation, and, increasingly, man-made activities. With the emergence of climate change as a major factor reshaping water quality and availability, the need to understand interactions between hydrochemistry and geology has never been greater. Hydrogeochemistry of Aquatic Ecosystems meets this need by offering foundational knowledge about the hydrochemistry of different types of aquatic systems, the nature of their interactions with various pollutants and geological processes, and the possibilities and dangers of human intervention. With a particular focus on aqueous resource conservation and restoration, this is a vital, timely guide to a potentially life-saving subject. Hydrogeochemistry of Aquatic Ecosystems readers will also find: Detailed treatment of water-sediment interactions, arsenic and fluoride enrichment, sand mining, and many other subjects Coverage throughout of solute acquisition processes, the carbon cycle, and nutrient geochemistry Case studies from Asia and Africa demonstrating both natural and anthropogenic hydrogeochemical interactions Hydrogeochemistry of Aquatic Ecosystems is indispensable for professionals and researchers in environmental science and environmental engineering, as well as scholars and advanced graduate students working on aquatic ecosystems or effects of climate change.

Download or read book Speciation Studies in Soil Sediment and Environmental Samples written by Sezgin Bakirdere and published by CRC Press. This book was released on 2013-09-26 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments clearly indicate that speciation studies in biological and environmental matrices are much more important than the total element determination due to the tremendous difference in bioavailability and toxicity of various chemical forms of a particular element. Different separation-detection techniques and hyphenated systems—each with its own advantages and disadvantages with respect to precision, sensitivity and detection limit—have been developed for the identification and quantification of the species present in systems at ultra-trace levels. This book aims to evaluate the speciation analysis in depth and present a comprehensive review of state-of-the-art analytical approaches used for the speciation of elements in environmental samples.
Download or read book Speciation of Inorganic Arsenic and Selenium in Contaminated Ground Water Samples Collected from Two Areas Alkermiah and Al Sawani in Tripoli Libya written by A. Etorki and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deals with the assessment of the arsenic and selenium concentration levels in ground water in two districts of Tripoli, Libya. The study conducted from March 2009 to January 2010 and 14 samples of ground water were collected and analyzed every two months using inductively coupled plasma optical emission spectroscopy (ICP-OES). A novel absorbent was prepared by 1,3-dimercapto propane sulphonic acid chemically modifying mesoporous titanium dioxide nanoparticles and was employed as micro column packing material for simultaneous speciation of inorganic arsenic and selenium species. As and Se species could be adsorbed quantitatively on 1,3-dimercapto propane sulphuric acid modified TiO2 nanoparticles within a pH range of 3-7 and only As(III) could be quantitatively retained on the column within a pH of 10 while As(V) and Se(IV) were passed through the column without the retention. The results show that arsenic levels in ground water varied from 1.05 to 31.08 ng/ml with a mean value of 4.5 ±0.34, which is high than the recommended World Health Organization (WHO) guidelines of 10 ng/ml for drinking water in some ground water samples. The data generated in this study will provide base line values for monitoring arsenic concentrations in ground water in surveyed area.
