Download or read book Technetium in the Environment written by G. Desmet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of technetium (in 1937, by Perrier and Segre), technetium-99 and technetium-99m have become most familiar in the specialised literature, the behaviour of the former being of concern regarding its health impact, the latter having been used intensively in medical tests for many years. The knowledge of the characteristics and behaviour of this element in nature is currently increasing exponentially. It has become clear, however, that there is still a serious shortage of information needed to assess properly its burden and impact on man and his environment. Technetium may indeed be released from nuclear installations or as a waste product from medical applications. It is generally considered to be highly mobile as the anion TcOi, but it is also suspected to be readily reduced in soils and metabolised in living beings into lower oxidation states. The seminar was planned to analyse thoroughly the experimental results obtained up to now and to make recommendations of specific issues requiring further research. This book presents the papers of the different sessions in the order of presentation, and the conclusions drawn by three discussion groups which dealt separately with: problems of sources and distribution of man-made technetium and its radiological consequences; the chemical behaviour of technetium in different ecosystems; biochemical reactions and binding with macromolecules in various life systems. vi Preface The editors, together with the Programme Committee of the Seminar, wish to express their gratitude to the chairmen of the different sessions for their summary of the group discussions.

A variety of human activities, including municipal waste disposal, industrial emissions, military testing, and agricultural practices have left their impacts on soils in the form of elevated, and locally high concentrations of toxicants. In several cases sources have not yet been stopped and contamination continues. Decisions on the management of contaminated sites require information on the extent to which toxicants adversely affect the soil ecosystem. For this purpose, it is often insufficient to extrapolate from abiotic sampling. The detection of a toxicant in the abiotic environment usually does not allow a very strong conclusion on the potential hazards.

Download or read book Riparian Landscapes written by George Patrick Malanson and published by Cambridge University Press. This book was released on 1993-05-27 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.
Download or read book cotoxicochimie des hydrocarbures written by PICOT André and published by Lavoisier. This book was released on 2013-04-15 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’écotoxicochimie, est une nouvelle branche de l’écologie qui se propose d’aborder les atteintes néfastes des produits chimiques sur l’environnement et la santé, à partir des données récentes de la chimie et de la biologie, en s’appuyant sur la toxicochimie, discipline d’interface élaborée en 1979. Les hydrocarbures, famille de base des composés organiques, ont été sélectionnés comme première approche dans Écotoxicochimie – Applications aux hydrocarbures. Ces produits chimiques sont à l’origine de la carbochimie et de la pétrochimie et leur prise en compte a permis de jeter les bases d’une prévention des risques aussi bien toxicochimiques qu’écotoxicochimiques. Risques liés en particulier à toutes les pollutions hydrocarbonées qui devraient être beaucoup mieux encadrées, tant en milieu domestique que dans les milieux de travail ou dans l’environnement. Ainsi ces hydrocarbures sont impliqués dans des pollutions maritimes retentissantes, qui restent malheureusement toujours d’actualité. Si les pollutions engendrées par l’exploitation maritime du pétrole sont également très inquiétantes, un autre sujet apparaît de plus en plus préoccupant avec l’extraction du gaz et des huiles de schiste, dont la technique mise en œuvre faisant appel à la fracturation hydraulique horizontale, est constituée d’un véritable cocktail chimique à faire frémir bien des toxicologues avertis… Sans précédent dans la littérature scientifique, toutes les propriétés toxiques des composés les plus utilisés sont présentées clairement dans cet ouvrage, à partir des références bibliographiques les plus actualisées. En tant que chimistes, spécialistes en toxicochimie, soucieux de comprendre pourquoi certains produits chimiques peuvent être dangereux pour la santé et l’environnement, les auteurs André Picot et Frédéric Montandon associés à plusieurs autres spécialistes, présentent, à la fin de l’ouvrage, une approche préventive, basée sur la sélection de produits de substitution notamment pour les solvants organiques. Trente-quatre fiches résumées dites de ToxicoÉcotoxicoChimie (FRTEC) devraient permettre de faire le bon choix parmi les principaux hydrocarbures couramment utilisés, en particulier comme solvants, et ceci dans de multiples disciplines. Par son approche novatrice, cet ouvrage sera indispensable aux professionnels des industries, des PMI et PME de tous les domaines traitant ou utilisant les hydrocarbures ou leurs dérivés, mais aussi aux responsables de santé publique ou des milieux de travail, aux organisations gouvernementales et non gouvernementales, et aux écologistes de tous horizons… sans oublier les enseignants et étudiants en chimie, en biologie et en écologie désireux de mieux comprendre pourquoi la chimie est à la base de la vie, qu’il nous faut protéger au mieux.
Download or read book Weariness of the Self written by Alain Ehrenberg and published by McGill-Queen's Press - MQUP. This book was released on 2010 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Depression, once a subfield of neurosis, has become the most diagnosed mental disorder in the world. Why and how has depression become such a topical illness and what does it tell us about changing ideas of the individual and society? Alain Ehrenberg investigates the history of depression and depressive symptoms across twentieth-century psychiatry, showing that identifying depression is far more difficult than a simple diagnostic distinction between normal and pathological sadness - the one constant in the history of depression is its changing definition. Drawing on the accumulated knowledge of a lifetime devoted to the study of the individual in modern democratic society, Ehrenberg shows that the phenomenon of modern depression is not a construction of the pharmaceutical industry but a pathology arising from inadequacy in a social context where success is attributed to, and expected of, the autonomous individual. In so doing, he provides both a novel and convincing description of the illness that clarifies the intertwining relationship between its diagnostic history and changes in social norms and values. The first book to offer both a global sociological view of contemporary depression and a detailed description of psychiatric reasoning and its transformation - from the invention of electroshock therapy to mass consumption of Prozac - The Weariness of the Self offers a compelling exploration of depression as social fact.
Download or read book Marine Radioactivity written by and published by Elsevier. This book was released on 2004-09-17 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on Marine Radioactivity sets out to cover most of the aspects of marine radioactivity which have been the focus of scientific study in recent decades. The authors and their reviews divide into topic areas which have defined the field over its history. They cover the suite of natural radioisotopes which have been present in the oceans since their formation and quantitatively dominate the inventory of radioactivity in the oceans. Also addressed are the suite of artificial radionuclides introduced to the oceans as a consequence of the use of the atom for development of nuclear energy, nuclear weapons and various applications of nuclear science. The major source of these continues to derive from the global fallout of atmospheric tests of nuclear weapons in the 1950s and 1960s but also includes both planned and accidental releases of radioactivity from both civilian and military nuclear technology. The other division of the major study direction depends on whether the objective is to use the radionuclides as powerful tools to study oceanic processes, to describe and understand the ocean distribution of the various natural or artificial radionuclides or to assess the different radionuclides' impact on and pathways to man or marine organisms. The oceans cover 70% of the Earth's surface and thus contains a corresponding large share of the Earth's radioactivity. Marine Radioactivity covers topics of recent scientific study in this young field. It examines both natural radioactivity (radioactivity naturally present in oceans since their formation) and artificial radioactivity (radioactivity introduced by man and use of atomic and nuclear energy) with regard to possible effects on the global environment.
