Download or read book Contamination en métaux lourds des eaux de surface et des sédiments du Val de Milluni (Andes Boliviennes) par des déchets miniers written by Matías Miguel Salvarredy Aranguren and published by . This book was released on 2008 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sur le site minier de Milluni (Bolivie, Altiplano, 4800 m asl), la contamination des eaux de surface et des sédiments par les métaux lourds a été étudiée en combinant des approches géochimiques, minéralogiques et hydrochimiques. Pour les différents métaux, les sources minérales de la contamination ont été établies, ainsi que les processus géochimiques d'altération des minéraux primaires en minéraux tertiaires. La compréhension des mécanismes géochimiques en jeu et les bilans réalisés ont permis de déterminer les origines et les modes de transport et de contrôle des métaux dans cet environnement. Enfin, les carottages des sédiments lacustres et des tourbières ont permis d'évaluer l'évolution historique de la contamination en métaux lourds, notamment au cours du siècle dernier.

Book Synopsis The Elements of Environmental Pollution by : John Rieuwerts
Download or read book The Elements of Environmental Pollution written by John Rieuwerts and published by Routledge. This book was released on 2017-07-14 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental pollution is one of humanity’s most pressing issues and will remain so for the foreseeable future. Anthropogenic activity is disturbing natural cycles and generating pollutants that are altering the atmosphere, accumulating in the food chain and contaminating the world’s soils, rivers and oceans. Human health and ecosystems continue to be damaged by toxic metals, persistent organic pollutants, radionuclides and other hazardous materials. The Elements of Environmental Pollution provides comprehensive coverage of this essential subject. It explains the key principles of pollution science, assesses human disturbances of natural element cycles and describes local and global pollution impacts, from smoggy cities, polluted lakes and toxic soils to climate change, ocean acidification and marine dead zones. The book is informed by the latest pollution research and benefits from numerous real-world examples and international case studies. A comprehensive glossary provides clear and concise explanations of key concepts. This textbook will support teaching and learning in environment-related university courses and will be vital reading for anyone with an interest in environmental protection.
Book Synopsis Chemical Speciation in the Environment by : A. M. Ure
Download or read book Chemical Speciation in the Environment written by A. M. Ure and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considerable recent research has focused on the topic of chemical speciation in the environment. It is increasingly realised that the distribution, mobility and biological availability of chemical elements depend not simply on their concentrations but, critically, on the forms in which they occur in natural systems. Continuing developments in analytical chemistry have made speciation practicable even where analytes are present at trace levels (as is often the case in natural samples). In the second edition of this book, the expertise of scientists involved in chemical speciation in various fields have been brought together to provide an overview of the current status of speciation science and indicate how the field may develop in the future.
Book Synopsis Harmonization of Leaching/Extraction Tests by : L. Heasman
Download or read book Harmonization of Leaching/Extraction Tests written by L. Heasman and published by Elsevier. This book was released on 1997-06-10 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a unique compilation on the use of leaching/extraction methods in different fields. The use of leaching test methods is increasing in various areas including: waste treatment and disposal; incineration of waste; soil clean-up and reuse of cleaned soil; sludge treatment. This has led to (and may increasingly lead to) the development of a large number of very similar tests in these different fields. However, these developments are taking place with no clear understanding of their mutual relationships. In view of these developments, efforts are needed to harmonize the leaching procedures that could be adapted for different matrices, as well as validate the use of existing tests in other fields. The development of a wide variety of leaching/extraction tests for different matrices is undesirable from a regulatory point of view and undesirable for industry. Clarity in testing is crucial in producer-consumer relations. This collective document will assist in improving the understanding of leaching from a variety of sources and will, where appropriate, help to bring together the approaches used in different technical fields and in different countries.
Book Synopsis Methane Emissions from Major Rice Ecosystems in Asia by : Heinz-Ulrich Neue
Download or read book Methane Emissions from Major Rice Ecosystems in Asia written by Heinz-Ulrich Neue and published by Springer Science & Business Media. This book was released on 2000 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice production is affected by changing climate conditions and has the dual role of contributing to global warming through emissions of the greenhouse gas methane. Climate change has been recognized as a major threat to the global environment. Because of insufficient field data, rice-growing countries face a problem when trying to comply with the United Nations Framework Convention on Climate Change stipulations to compile a national inventory of emissions and to explore mitigation options. Given the expected doubling in rice production in Asia, the need to evaluate the interaction between climate change and rice production is critical to forming a sound basis for future directions of technology developments by policy makers, agriculturists, environmentalists, rice producers, and rice consumers. The present book comprises two sections. The first part documents a comprehensive overview of the results achieved from an interregional research effort to quantify methane emission from major rice ecosystems and to identify efficient mitigation options. This research report broadens understanding of the contribution of rice cultivation to methane emissions and clarifies that emissions are relatively low, except in specific rice ecosystems, and that these high emissions could be ameliorated without sacrificing yield. The second section shows results from other projects that investigated the role of rice cultivators in field and laboratory approaches. The findings represent inputs for future modeling approaches in the role of rice cultivators. The expanded database generated by other projects is reflected in modeling efforts.
