Available in PDF, EPUB and Kindle. Book excerpt: In order to evaluate ultra-trace concentrations of MeHg in various matrices, a new HPLC-CV-AFS method was developed. To achieve exceptionally low limits of detection (0.4 ng/L) Hg species are first trapped on the preconcentration column with possibility of on-line preconcentration of up to 200 mL of sample. Then trapped Hg species are eluted and separated on HPLC column and detected by CV-AFS. The robustness of the method was validated with 6 certified reference materials (DOLT-2, DOLT-4, DORM-3, TORT-2, IAEA-140/TM, ERM®-CC580), which showed recovery in the range of 88 – 104%. Moreover, a comparison between MeHg concentrations in the biological tissues carried out by species-specific isotope dilution gas chromatography inductively coupled plasma mass spectrometry and HPLC-CV-AFS showed very good correlation (R2 = 0.97) what is further advocating the reliability of the newly developed method.

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.

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 Environmental Chemistry and Toxicology of Mercury written by Guangliang Liu and published by John Wiley & Sons. This book was released on 2011-11-07 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the fundamentals, recent developments, and future research needs for critical mercury transformation and transport processes, as well as the experimental methods that have been employed in recent studies. The coverage discusses the environmental behavior and toxicological effects of mercury on organisms, including humans, and provides case studies at the end of each chapter. Bringing together information normally spread across several books, this text is unique in covering the entire mercury cycle and providing a baseline for what is known and what uncertainties remain in respect to mercury cycling.
Download or read book Elemental Speciation written by Joseph A. Caruso and published by Elsevier Science Limited. This book was released on 2000 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. This book provides a comprehensive discussion of the major aspects involved in elemental speciation. Sample preparation, separation techniques, instrumentation and quality assurance are all discussed. In addition, individual chapters are devoted to speciation of environmental samples and speciation of biological, clinical, and nutritional samples. Individual chapters are written by leaders in the field, and the book has been organized so that the reader may learn how to collect a sample and prepare it. Ways to separate and detect analytes of interest, and steps to take to ensure the validity of the measurements are also discussed. This book is unique in its comprehensive treatment of this subject.
