Available in PDF, EPUB and Kindle. Book excerpt: At the First International Symposium on Aquatic Oligochaete Biology in Sidney, B. C. , the suggestion was made to hold the second in Pallanza, on Lake Maggiore, at the C. N. R. -Istituto Italiano di Idrobiologia. At the same time it was decided that there should be a symposium every third year. The organization of the symposium was made considerably easier by the Senior Editor's having been in personal contact with several Russian colleagues (courtesy of a kind invitation from the U. S. S. R. Academy of Sciences), the 'Hamburg Group' and the Junior Editor. Correspondence with various students of Oligochaeta also furnished many useful suggestions. The Second International Symposium on Aquatic Oligochaete Biology was therefore held in Pallanza in late September 1982 and was attended by 53 scientists from 16 countries in Europe, North America, Asia and Australia. No review papers were formally invited as this had already been done at the first symposium: all the papers were accordingly allotted the same time for oral presentation. These proceedings contain all papers Hrabe and Slepukhina, which were given in absentia, as it presented at the symposium, including those by was impossible for the authors to join the group. The main topics were taxonomy and evolution of Oligo chaeta, life-cyle and population studies, the role of Oligo chaeta in assessing water pollution, physiolog ical studies, community and distribution studies. Special taxonomic workshops took place in the evenings.

Book Synopsis Lessons from Amazonia by : Richard O. Bierregaard
Download or read book Lessons from Amazonia written by Richard O. Bierregaard and published by Yale University Press. This book was released on 2001-12-11 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deforestation is occurring at an alarming rate in many parts of the world, causing destruction of natural habitat and fragmentation of what remains. Nowhere is this problem more pressing than in the Amazon rainforest, which is rapidly vanishing in the face of enormous pressure from humans to exploit it. This book presents the results of the longest-running and most comprehensive study of forest fragmentation ever undertaken, the Biological Dynamics of Forest Fragments Project (BDFFP) in central Amazonia, the only experimental study of tropical forest fragmentation in which baseline data are available before isolation from continuous forest took place.A joint project of Brazil’s National Institute for Research in Amazonia and the U.S. Smithsonian Institution, the BDFFP has investigated the many effects that habitat fragmentation has on plants, invertebrates, and vertebrates. The book provides an overview of the BDFFP, reports on its case studies, looks at forest ecology and tree genetics, and considers what issues are involved in establishing conservation and management guidelines.

Book Synopsis Analyse du risque chimique en milieu marin by : Michel Marchand
Download or read book Analyse du risque chimique en milieu marin written by Michel Marchand and published by Editions Quae. This book was released on 2006 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: La législation européenne sur les produits chimiques impose une évaluation des risques afin d'assurer une protection de l'homme et de l'environnement. La procédure adoptée est basée sur un manuel technique d'évaluation du risque chimique commun à l'Union européenne ("Technical Guidance Document" ou TGD). La présentation de ce document est limitée à la seule approche environnementale pour la protection des milieux aquatiques et plus précisément du milieu marin. Ceci constitue une référence pour les gestionnaires de l'environnement, notamment du milieu littoral, confrontés aux problèmes posés par la contamination chimique des milieux aquatiques.

Download or read book Contaminated Sediments in Ports and Waterways written by Division on Engineering and Physical Sciences and published by National Academies Press. This book was released on 1997-04-20 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated marine sediments threaten ecosystems, marine resources, and human health. They can have major economic impacts when controversies over risks and costs of sediment management interfere with needs to dredge major ports. Contaminated Sediments in Ports and Waterways examines management and technology issues and provides guidance that will help officials make timely decisions and use technologies effectively. The book includes recommendations with a view toward improving decision making, developing cost-effective technologies, and promoting the successful completion of cleanup projects. The volume assesses the state of practice and research and development status of both short-term and longer-term remediation methods. The committee provides a conceptual overview for risk-based contaminated sediment management that can be used to develop plans that address complex technological, political, and legal issues and the interests of various stakeholders. The book emphasizes the need for proper assessment of conditions at sediment sites and adequate control of contamination sources.
Book Synopsis Bioévaluation de la qualité environnementale des sédiments portuaires et des zones d'immersion by : Claude Alzieu
Download or read book Bioévaluation de la qualité environnementale des sédiments portuaires et des zones d'immersion written by Claude Alzieu and published by Editions Quae. This book was released on 2003 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage propose des méthodes de suivi qui permettent de vérifier l'hypothèse préalable d'impact et d'y apporter si nécessaire les mesures correctives. Ainsi, l'indice d'évaluation de l'endofaune côtière permet d'affecter à chaque sédiment une note de qualité biologique et, grâce aux propriétés accumulatrices des bivalves, les procédures de la surveillance en mer ouverte offrent la possibilité de contrôler les effets des apports en contaminants. Un chapitre est consacré à la surveillance des apports d'un dépôt à terre. Les gestionnaires, scientifiques et techniciens de l'environnement y trouveront une démarche ascendante qui leur permettra de suivre les recommandations des lignes directrices OSPAR.
Book Synopsis Caractérisation et traitement de sédiments de dragage contenant des polluants métalliques by : Franck Marot

This book was released on 1998 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette étude est d'évaluer les possibilités de décontamination des vases de dragage polluées par des métaux lourds et de déterminer leur devenir après traitement. Les travaux portent sur des sédiments d'estuaires et de canaux prélèves sur différents sites français. Dans un premier temps, les caractérisations physiques, chimiques et minérales de ces produits ont montré des pollutions complexes et parfois très marquées. Les études de spéciation menées par une succession de séparations physiques, d'observations binoculaires et d'analyses au microscope électronique a balayage et a la microsonde, ont permis de déterminer pour chaque sédiment, les principaux porteurs de métaux (microsulfures, précipitations de carbonates, adsorptions sur des grains d'oxyde de fer, particules anthropiques,...). A l'issue de ces travaux, des essais de traitement physique et physico-chimique visant à concentrer ces porteurs sur une fraction pondérale réduite, ont été effectués. La flottation a conduit aux résultats les plus prometteurs. L'efficacité de cette technique de tri est cependant très sensible à la nature des collecteurs chimiques utilises et seuls des tests d'optimisation sont en mesure de parfaire leur choix. Par ailleurs, selon les objectifs de décontamination fixés, des séparations gravimétriques ou densimétriques complémentaires peuvent permettre d'affiner le traitement. Dans un troisième temps, le devenir des matériaux traités a été étudié sur le plan du comportement mécanique. Avec des fractions fines souvent importantes, la consolidation de ces produits est très lente. Pour prédire son évolution dans le temps, une étude expérimentale a été menée en centrifugeuse sous macrogravité. Les degrés de consolidation atteints en fin d'essai (90% après un temps équivalent de 900 jours) et les tassements mesures (70% de la hauteur initiale) ont montré la lenteur et l'importance du phénomène étudié.
