Book Synopsis Pollution of the North Sea by : Wim Salomons
Download or read book Pollution of the North Sea written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 753 pages. Available in PDF, EPUB and Kindle. Book excerpt: This preface is being written at a time of exceptional public interest in the North Sea, following media head lines on toxic algal blooms, the mass mortality of common seals, and concern over pollution levels. These headlines may suggest that pollution of the North Sea is a recent event. This is not the case. Although no data are available (methods simply did not exist), it is safe to assume that emission (both into air and water) of heavy metals already started to increase in the 19th cen tury. The growth of cities and introduction of sewer sys tems led to the discharge of raw sewage and sewage sludge. The introduction of man-made (xenobiotic) organ ic chemicals and their subsequent emission into the North Sea commenced before the second world war. The shallower and coastal areas of the North Sea receive the highest concentrations of these pollutants. Not unexpectedly, these areas - some Norwegian fjords, the Dutch coast, the German Bight - show signs of ecosystem deterioration and eutrophication. A certain percentage of the pollutants does not remain in the North Sea but is "exported" to the Atlantic. The North Sea therefore con tributes to the global input of pollutants to the world's oceans. The major part of the pollutants accumulate in the North Sea and are incorporated in the bottom sediments. Although they are "out of sight", they should not be "out of mind".

Download or read book Ocurrence, Transport and Fate of Persistent Organic Pollutants in the Global Ocean written by and published by . This book was released on 2015 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Open Ocean has been recognized as playing a key role on global dynamics of pollutants due to its large coverage of the planet surface, its high degradation potential and its sink and accumulation capacities towards anthropogenic chemicals. Nevertheless, there is a dearth of measurements of contaminants in the Open Ocean lower atmosphere, water column and trophic chain as a result of its remoteness and wide spatial reach. Persistent organic pollutants (POPs) are an important class of chemical contaminants due to their particular characteristics such as persistency, bioaccumulation potential, high toxicity and long range environmental transport capacity. Even though previous studies report their occurrence in the marine environment, the processes and magnitude of their fate, transport and sinks in the Open Ocean remain uncharacterized. In this Thesis two groups of organic contaminants have been selected in order to study POPs dynamics and fate in the oceanic environment. Polycyclic Aromatic Hydrocarbons (PAHs) are organic pollutants generated during incomplete combustion of fossil fuels and organic matter, but as well coming from petrogenic and biogenic natural sources. PAHs are semivolatile and highly mobile between the atmosphere and aqueous systems. Perfluoroalkylated substances (PFASs) are anthropogenic halogenated pollutants, recently developed for industrial and consumer goods usage. They are extremely persistent and exhibit higher solubility and lower hydrophobicity than most POPs, which makes them prone to be found in aqueous matrixes. During the Malaspina 2010 circumnavigation cruise across the Atlantic, Pacific and Indian oceans (35°N- 40°S), 64 PAHs were measured in the gas, aerosol, rainwater, dissolved, particulate and plankton matrixes, and 11 PFASs were quantified in dissolved phase at surface and deep chlorophyll maximum depth seawater. Degradation and atmospheric deposition of PAHs was assessed for dry deposition, wet deposition and diffusive air-water exchange, suggesting approaches for their global estimation, and proposing a global budget for PFAS, PAHs, and other semivolatile aromatic-like compounds, and their effect in the carbon global cycle. Dry deposition was obtained by direct measurements on board and parametrized for the whole tropical and subtropical Ocean; wet deposition was quantified from the precipitation rainwater gathered during the cruise; and diffusive exchange was calculated from the measured PAHs concentrations in the gas and dissolved phases, concurrently with the environmental parameters affecting volatilization and absorption (temperature, wind speed, salinity, dissolved organic carbon among others). Moreover, vertical distribution processes and influencing parameters in the surface mixed layer of the water column were assessed for PAHs and PFASs. Processes evaluated for PAHs include the vertical fluxes associated to the organic matter sinking (biological pump), biomass dilution, planktonic degradation, and air-water-particle exchange. For PFASs, the biological pump and eddy diffusive fluxes (based on turbulence eddy diffusion coefficients measured concurrently to the PFASs sampling) were assessed empirically for the first time in literature. The analysis of the complex feedback established between atmospheric depositional fluxes and the diffusive, degradative and biological pumps fluxes in the marine water column at a global scale is also covered. Furthermore, a wide array of understudied environmental parameters are reviewed as plausible factors affecting POPs fate in the Open Ocean, and a proposal of the research directions to follow and missing gaps to be filled is done. Amongst the innovative outcomes of this study, it can be highlighted the comprehensive sampling covering the tropical and subtropical global oceans, and the large amount of experimentally determined processes and influencing factors in order to better understand the global fate of chemical organic pollutants in the Open Ocean.
Book Synopsis Marine Anthropogenic Litter by : Melanie Bergmann
Download or read book Marine Anthropogenic Litter written by Melanie Bergmann and published by Springer. This book was released on 2015-06-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Protection of the North Sea focuses on measures and initiatives for the protection of the North Sea. The book first discusses the physical features, North Sea resources, and biological considerations. The compilation then takes a look at the distribution of anthropogenic organic compounds in the North Sea, including analytical aspects and reporting format for polychlorinated biphenyls (PCBs); transport of PCB in abiotic phases in rivers, estuaries, and the North Sea; and PCB in biota. The text examines the environmental impacts of organic chemicals. History of pollution; environmental effects of chemicals; effects of chemicals on marine biota; and chemicals of potential concern are described. The compilation also underscores the sources of pesticides in the North Sea; environmental impacts of PCBs in the marine environment; and contamination of the North Sea by the production and utilization of organic chemicals. The book also looks at environmental protection strategies for organic chemicals; assessment of environmental impacts of nutrients in the North Sea from the perspectives of the fertilizer and detergents industries; and pathology of fish diseases in the North Sea. The compilation is a good source of data for readers interested in environmental protection.
Book Synopsis Global Sources of Local Pollution by : National Research Council
Download or read book Global Sources of Local Pollution written by National Research Council and published by National Academies Press. This book was released on 2010-02-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in air pollution monitoring and modeling capabilities have made it possible to show that air pollution can be transported long distances and that adverse impacts of emitted pollutants cannot be confined to one country or even one continent. Pollutants from traffic, cooking stoves, and factories emitted half a world away can make the air we inhale today more hazardous for our health. The relative importance of this "imported" pollution is likely to increase, as emissions in developing countries grow, and air quality standards in industrial countries are tightened. Global Sources of Local Pollution examines the impact of the long-range transport of four key air pollutants (ozone, particulate matter, mercury, and persistent organic pollutants) on air quality and pollutant deposition in the United States. It also explores the environmental impacts of U.S. emissions on other parts of the world. The book recommends that the United States work with the international community to develop an integrated system for determining pollution sources and impacts and to design effective response strategies. This book will be useful to international, federal, state, and local policy makers responsible for understanding and managing air pollution and its impacts on human health and well-being.

Book Synopsis Oil in the Sea III by : National Research Council
Download or read book Oil in the Sea III written by National Research Council and published by National Academies Press. This book was released on 2003-03-14 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
Book Synopsis Biomagnification and Fate of Persistent Organic Pollutants (POPs) in Marine Mammal Food Webs in the Northeastern Pacific Ocean by : Donna Lynn Cullon
Download or read book Biomagnification and Fate of Persistent Organic Pollutants (POPs) in Marine Mammal Food Webs in the Northeastern Pacific Ocean written by Donna Lynn Cullon and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Elevated polychlorinated biphenyl (PCB) concentrations have been detected in marine mammals inhabiting the Strait of Georgia, British Columbia (Canada) and Puget Sound, Washington State (USA). This raises concerns about adverse health effects and underscores the importance of documenting source, transport, and fate of contaminants. This marine mammal-oriented study- (1) examines dietary exposure to complex mixtures of persistent organic pollutants (POPs); (2) characterizes POP accumulations using congener-specific contaminant analyses, stable isotope ratios, and multivariate statistical methods; and (3) explores some of the influencing factors for POP bioaccumulation in marine mammals. A first application of a food basket approach to assessing real-world dietary exposure to mixtures of chemicals in marine mammals has revealed Puget Sound as a regional?hotspot? for PCB contamination. The consistency between PCB concentrations in Puget Sound and the Strait of Georgia harbour seals (Phoca vitulina) and their food baskets validates the use of this method as a basis for exploring dietary exposure, metabolism, biomagnification, and health risks in marine mammals. Concentration rankings of POPs and estimated daily intakes based on our food baskets suggests that both legacy (e.g., PCB, dichlorodiphenyltrichloroethane [DDT]) and new (polybrominated diphenyl ethers [PBDEs]) POPs may pose potential health risks to seals. Accumulations of PCBs in the Strait of Georgia seal food web demonstrate the bioaccumulative nature and persistence of PCBs. Correlations of PCB concentrations with physicochemical properties and trophic level revealed the important role that metabolism plays in biomagnification in seals, alongside trophic level and log Kow. We estimate a PCB load of 77 kg within the Strait of Georgia biomass, with the largest proportion (36 %) detected in marine mammals. Dietary exposure of POPs to resident killer whales (Orcinus orca) was assessed by measuring POPs in four stocks of chinook salmon (Oncorhynchus tshawytscha), their primary prey. Differences in POP concentrations between chinook smolts and returning adults suggest that the majority of POPs are acquired at sea during the major growth period in their life cycle. Higher POP concentrations and low lipid content were observed among the more southerly stocks suggesting a migration-associated metabolism and loss of lighter congeners, thereby exposing southern residents to more highly contaminated chinook salmon. Consumption on a lipid-weight basis, (higher consumption on a wet weight basis), as well as consuming prey from a more contaminated region, likely increases killer whale exposure to POPs, offering an explanation for higher contaminant burdens in southern residents. While previous research has examined species inhabiting different trophic levels or food chains in other regions, this study has provided an assessment of POP dietary exposure, biomagnification, and influencing factors on trophic accumulations in a North-eastern Pacific marine mammal food web. These results have provided further insight into the influence of such factors as age, sex, lipid content, diet, migration-related metabolism, physicochemical properties (degree of chlorination, log Kow), and chemical structure on POP accumulation in marine mammals. We have identified the largely unregulated PBDEs as posing potential health risks to marine mammals and offered a means to update existing tissue residue guidelines for the protection of wildlife.
