Available in PDF, EPUB and Kindle. Book excerpt: Sediments contaminated by human activities usually contain a mixture of chemicals that produce unforeseen combined toxic effects in organisms. Thus, traditional risk assessments based on the concentrations of chemicals are unlikely to produce realistic data on toxicity. In the CONTEST project, 19 biotests were evaluated using a model contaminated sediment from the Baltic Sea. Most of the biotests applied showed concentration-dependent toxicity related to the degree of chemical pollution measured in the test sediment with some variability in the sensitivity of the test organism and the endpoint. The different biotests were analysed according to specially designed assessment criteria, and the results are foreseen to be useful for end-user groups including environmental authorities, private companies and industries, environmental laboratories, consultants, and the scientific community.

This book was released on 2017-04-04 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive science-based textbook on the biology and ecology of the Baltic Sea, one of the world’s largest brackish water bodies. The aim of this book is to provide students and other readers with knowledge about the conditions for life in brackish water, the functioning of the Baltic Sea ecosystem and its environmental problems and management. It highlights biological variation along the unique environmental gradients of the brackish Baltic Sea Area (the Baltic Sea, Belt Sea and Kattegat), especially those in salinity and climate. pt;font-family:"Arial","sans-serif"; color:#262626">The first part of the book presents the challenges for life processes and ecosystem dynamics that result from the Baltic Sea’s highly variable recent geological history and geographical isolation. The second part explains interactions between organisms and their environment, including biogeochemical cycles, patterns of biodiversity, genetic diversity and evolution, biological invasions and physiological adaptations. In the third part, the subsystems of the Baltic Sea ecosystem – the pelagic zone, the sea ice, the deep soft sea beds, the phytobenthic zone, the sandy coasts, and estuaries and coastal lagoons – are treated in detail with respect to the structure and function of communities and habitats and consequences of natural and anthropogenic constraints, such as climate change, discharges of nutrients and hazardous substances. Finally, the fourth part of the book discusses monitoring and ecosystem-based management to deal with contemporary and emerging threats to the ecosystem’s health.

Download or read book Contaminated Sediments written by Marianne Olsen and published by Nordic Council of Ministers. This book was released on 2019-07-09 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nordic Council of Ministers have recognized the need to compile the knowledge of sediment remediation strategies and to evaluate different remediation approaches. The objective of this report is to give a status of regulatory framework and sediment management within selected Nordic countries (Norway, Sweden, Finland and Denmark). In addition, the report gives a short overview of international knowledge on remediation approaches, techniques, and materials. Governance and regulatory instruments in dealing with contaminated sediments vary between countries. Of the countries presented, only Norwegian environmental authorities have implemented a national strategy for remediation of marine contaminated sediments. A Nordic database of clean-up projects and long-term monitoring would improve the exchange of knowledge between the Nordic countries.

This book was released on 2007-10-11 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first interdisciplinary book on the mobilization of nutrients and pollutants in the water phase due to hydrodynamic processes. Coverage includes the formation of aggregates in turbulent water; flocks and biofilms from organic reactions; and the formation of new surfaces for re-adsorption of dissolved pollutants. The book gathers papers resulting from an International Symposium on Sediment Dynamics and Pollutant Mobility in River Basins in Hamburg, Germany, March, 2006.

Book excerpt: A baseline study on the concentrations of contaminants in the Baltic Sea surface sediments was carried out in 1993. The study was initiated by the International Council for the Exploration of the Sea as a response to the request by the Helsinki Commission. All subareas of the Baltic Sea were covered. In addition to surface sediment samples for contaminant analyses, sedimentation rates were determined and a mineralogical study as well as a sediment characterization of the sediment cores were carried out. A recommendation is given on the use of sediment studies in relation to the monitoring of the state of the Baltic Sea.

Download or read book Ecosystems and Living Resources of the Baltic Sea written by Evald Ojaveer and published by Springer. This book was released on 2017-03-08 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a reconstruction of the formation of the environmental conditions and biota in the present-day Baltic Sea area during the last glacial cycle and thereafter under the influence of extra-terrestrial, climatic and geological factors. Abiotic conditions in the contemporary Baltic Sea (water salinity, temperature, oxygen and light conditions, currents and other water movements) are characterized and in this background the natural regional system of the sea has been generated. Important issues are considered such as life forms in the Baltic and their dependence on the natural environment (both in the conditions of the relative stable environment and during the regime shifts), as well as anthropogenic influences and the basic differences between the areas of the World Ocean and the brackish Baltic Sea. This book also equips readers with basic principles of assessments and management of ecosystems and fish resources (including the long-term assessment and forecast on ecosystems and fish resources) and provides information on the structures of international collaboration developed in the Baltic Sea.

Download or read book A Systems Analysis of the Baltic Sea written by F.V. Wulff and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: During recent decades, large-scale effects of pollution on marine estuaries and even entire enclosed coastal seas have become apparent. One of the first regions where this was observed is the Baltic Sea, whereby the appearance of anoxic deep basins, extensive algal blooms and elimination of top predators like eagles and seals indicated effects of both increased nutrient inputs and toxic substances. This book describes the physical, biochemical and ecological processes that govern inputs, distribution and ecological effects of nutrients and toxic substances in the Baltic Sea. Extensive reviews are supplemented by budgets and dynamic simulation models. This book is highly interdisciplinary and uses a systems approach for analyzing and describing a marine ecosystem. It gives an overview of the Baltic Sea, but is useful for any marine scientist studying large marine ecosystems.

Download or read book Eutrophication in the Baltic Sea written by Lars Håkanson and published by Springer Science & Business Media. This book was released on 2008-09-26 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years the reduction of eutrophication in the Baltic Sea has been a hot issue for mass-media, science, political parties and environmental action groups with manifold implications related to fisheries (will the Baltic cod survive?), sustainable coastal development (have billions of Euros been wasted on nitrogen reductions?), ecotoxicology (can we safely eat Baltic fish?). This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This includes a very special process for the Baltic Sea: land uplift. After being depressed by the glacial ice, the land is now slowly rising adding vast amounts of previously deposited nutrients and clay particles to the system. 110,000 to 140,000 tons of phosphorus per year are added to the system from land uplift, in comparison to the 30,000 tons of phosphorus per year from rivers.
