Download or read book Determination and Speciation of Mercury in Sediment and Related Samples from Greece and Scotland written by Olga Cavoura and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury is a global pollutant. Research is needed to improve methods for Hg detection and improve understanding of its biogeochemical cycle and risks to human health. In this study, a simple, colorimetric method utilising the reaction of Hg with copper(I)iodide was characterised and adapted for screening marine samples, and the speciation and relationships of Hg with other sediment parameters in contaminated environments was examined. Field application of the colorimetric method indicated Hg concentrations in sediments from West Scotland, U.K., and Kifissos River, Greece, were below Canadian sediment quality guideline values of 0.13 and 0.17 mg/kg for marine and freshwater sediment respectively, whereas sediment from the Falkirk area of the Union Canal, U.K., and Elefsina Bay, Greece, had Hg concentrations above probable effect levels (0.49 and 0.7 mg/kg). Total sediment Hg concentrations, determined quantitatively using cold-vapour atomic absorption spectrometry (AAS), ranged from 0.220 to 2.96 mg/kg in Elefsina Bay. Concentration was influenced by proximity to nearshore pollution sources but was not found to vary seasonally or be related to sediment organic matter content. Sequential extraction indicated that Hg speciation - hence mobility - varied between sites. No Hg was detected in the fish Mugil Cephalus indicating no threat to humans from consumption. Total sediment Hg concentrations in the Union Canal ranged from 22 to 1200 mg/kg. Both sequential extraction and speciation analysis using thermodesorption AAS indicated that ca.>70% of the Hg present was mobile. Analysis by gas chromatography inductively coupled plasma mass spectrometry showed that the methylmercury content was
Download or read book Handbook of Mineral Elements in Food written by de la Guardia and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral elements are found in foods and drink of all differenttypes, from drinking water through to mothers’ milk. Thesearch for mineral elements has shown that many trace andultratrace-level elements presented in food are required for ahealthy life. By identifying and analysing these elements, it ispossible to evaluate them for their specific health-givingproperties, and conversely, to isolate their less desirableproperties with a view to reducing or removing them altogether fromsome foods. The analysis of mineral elements requires a number ofdifferent techniques – some methods may be suitable for onefood type yet completely unsuited to another. The Handbook of Mineral Elements in Food is the firstbook to bring together the analytical techniques, the regulatoryand legislative framework, and the widest possible range of foodtypes into one comprehensive handbook for food scientists andtechnologists. Much of the book is based on the authors’ owndata, most of which is previously unpublished, making theHandbook of Mineral Elements in Food a vital andup-to-the-minute reference for food scientists in industry andacademia alike. Analytical chemists, nutritionists and food policymakers will also find it an invaluable resource. Showcasing contributions from international researchers, andconstituting a major resource for our future understanding of thetopic, the Handbook of Mineral Elements in Food is anessential reference and should be found wherever food science andtechnology are researched and taught.

Download or read book Global and Regional Mercury Cycles Sources Fluxes and Mass Balances written by W. Baeyens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential themes in the biochemical cycling of mercury are the relative importance of anthropogenic versus natural sources, transformation and migration processes at the local, regional and global scale, global emission inventories of different mercury sources (both point and diffuse) of both natural and anthropogenic origin. In this regard, Siberia, with its vast territory and variety of natural zones, is of special interest in the global mercury cycle and in terms of the influence of geographical zones on source and sink terms in regional budgets. Siberia contains large areas of mercuriferous belts; natural deposits that emit mercury into the atmosphere and water. Siberian gold has been mined with the use of mercury since the early 1800s. But there, too, huge forest zones and vast areas of tundra and wetland (bogs) can act as efficient sinks for atmospheric mercury. Audience: Environmental scientists, legislators, politicians and the interested citizen wishing to gain a clear picture of the biogeochemical cycling of mercury.

Available in PDF, EPUB and Kindle. Book excerpt: Vapor Generation Techniques for Trace Element Analysis: Fundamental Aspects provides an overview and discussion of the fundamental aspects governing derivatization reactions of trace-level elements for analytical purposes. Vapor generation techniques coupled with atomic or mass spectrometry have been employed for over 50 years, but their popularity has dramatically increased in recent years, especially as alternative vapor generation approaches have been developed. This book bridges the knowledge gap of the derivatization mechanisms that yield volatile compounds and provides an update on recent developments in vapor generation techniques used for the determination and speciation of trace elements by atomic optical and mass spectrometry. It will serve as a comprehensive, single-source overview of recent developments, providing readers with an understanding of the correct implementation—and limitations—of applying vapor generation techniques to everyday analytical problems facing the trace element analyst. - Covers reaction mechanisms and fundamental processes of vapor generation in detail - Includes classical and alternative vapor generation approaches: alkylation, chelation, plasma, photochemical and electrochemical - Guides the interpretation of experimental results and implementation of vapor generation techniques in the laboratory

Download or read book Analytical Methods in the Determination of Bioactive Compounds and Elements in Food written by Magdalena Jeszka-Skowron and published by Springer Nature. This book was released on 2021-02-02 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most bioactive compounds have antioxidant activity, particularly tocochromanols, phenolics (flavonoids and phenolic acids), methylxantines and capsaicinoids. Some of these compounds have also other properties important for human health. For example, vitamin E protects against oxidative stress, but it is also known for its “non-antioxidant” functions, including cell signalling and antiproliferation. Selenium compounds and indoleamins are the components of the antioxidant enzymes. Selenium makes vitamin E acquisition easier and controls its physiological functions. In taking part in enzymatic reactions and protecting the cell against free radicals, selenium shows immunomodulative, antiphlogistic, and antiviral activity. Capsaicinoids possess not only antioxidant, but also antibacterial, analgesic, weight-reducing and thermoregulation properties. Studies have also demonstrated their gastroprotective and anticancer properties. Analytical Methods in the Determination of Bioactive Compounds and Elements in Food explores both the influence of particular compounds on human health and the methods used for their determination. Chapters describe various aspects of food and plant analysis, including chromatographic and non‐chromatographic approaches as well as hyphenated techniques. Readers of this book will gain a comprehensive understanding of the important groups of bioactive compounds relevant to human health.
