Available in PDF, EPUB and Kindle. Book excerpt: Lead in the Marine Environment covers the proceedings of the International Experts Discussion on Lead Occurrence, Fate, and Pollution in the Marine Environment, held in Rovinj, Yugoslavia on October 18-22, 1977. The book focuses on the release of lead to the environment, including the techniques, processes, and technologies involved in the analysis of lead in marine ecosystems. The selection first highlights the impact of human on coastal marine ecosystems; analysis of natural and industrial lead in marine ecosystems; and the occurrence of lead in Northeast Pacific and the effects of anthropogenic inputs. The book also looks at the voltammetric determination of the stability constants of the predominant labile lead complexes in sea water, as well as investigations on the nature of the effective carbonato ligand and experimental verification of a chemical model for trace metal speciation in sea water. The publication reviews studies of lead in water and biological materials using X-ray emission spectroscopy; theoretical studies of the chemical speciation of lead in sea water; and input of lead into the Mediterranean through rivers. The text also explains the chelation of lead by organic ligands in sea water and potentialities and limitations of atomic absorption spectroscopy in environmental and biological materials with reference to lead determinations. Concerns include aspects of chelation of heavy metal traces in sea water and typical lead values and analytical data for biological and environmental materials. The selection is a vital source of data for readers interested in studying the effects of lead on the environment.

Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.

Download or read book Bioaccumulation in Marine Organisms written by J.M. Neff and published by Elsevier. This book was released on 2002-04-16 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large volumes of produced water are generated and discharged to the coastal and ocean waters worldwide from offshore oil and gas production facilities. There is concern that the chemicals in the produced water may harm marine ecosystems. This book summarizes the bioavailability and marine ecotoxicology of metal and organic contaminants that may occur in oil well produced water at concentrations significantly higher than those in ambient seawater. The contaminants of concern include arsenic, barium, cadmium, chromium, copper, lead, mercury, radium isotopes, zinc, monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, phenols, and bis(2-ethylhexyl)phthalate. The first part of the book is a detailed discussion of the chemical composition of produced water from offshore oil wells worldwide and its fates following discharge to the ocean. The remaining chapters of the book summarize the current scientific literature on the sources and distributions in the ocean of each of the contaminants of concern and their bioaccumulation and toxicity to marine organisms. This book will be of value to: environmental scientists in the oil and gas industry; marine toxicologists and ecological risk assessors in academia, government, and industry; government regulatory agencies concerned with marine environmental protection. The book advances the concept that bioavailability evaluation must be included in all ecological risk assessments and other environmental assessments of chemical contaminants in marine and freshwater ecosystems.

Download or read book Chemistry in the Marine Environment written by R E Hester and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceans cover more than 70% of the earth's surface to an average depth of almost 4000 metres. It is therefore not surprising that exchanges that occur between ocean and atmosphere exert major influences on the global climate. In addition, there is great variety within the expanses of the ocean, including large temperature differences, and enormous biodiversity brought about by the great chemical diversity within the marine environment. Written by international experts in the field, Chemistry in the Marine Environment offers a multidisciplinary and authoritative review of this important topic. Included is a review of the opportunities and challenges in developing new pharmaceuticals from the sea and an examination of contamination and pollution in the marine environment, which is a cause of great concern world-wide. The international perspective of this book will engage the interest and attention of a wide readership, from chemical oceanographers to policymakers, from students in environmental science to those in oceanography programmes.

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.

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 447 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.

This book was released on 2019-08-05 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: While oceans are vast, they represent a fragile resource that must be protected if we want to protect our livelihoods and our planet. Marine pollution has been a topic of concern for a long time, and it has recently attracted the attention of scientists, environmentalists, economists, politicians and journalists in mainstream media. Besides providing food, transportation routes and other resources, the oceans serve as a heat absorbing sink which offsets the extreme heating effects of climate change, but only to a limited degree. Pollution in marine environments such as the oceans, poses a threat to coastal communities by affecting the fauna and flora in the environment and the health of the nearby population. This has a disruptive effect on the health and economy of these communities. Marine Pollution: Current Status, Impacts and Remedies emphasizes the limitations of marine resources that relevant environments provide. Readers will find chapters on methods to assess pollution as well as important information for identifying, measuring, and remediating various pollutants. The book also covers some known pollutants (heavy metals, organic pollutants, microplastics) and ways to manage these substances. Other issues covered in the book include problems caused by invasive species, and the ecological problems caused by pollutants which affect local fauna and flora. This book will prove to be a useful resource for students, researchers, and policymakers, who are working in environmental science, marine conservation and allied fields. [Series Intro] Marine Ecology: Current and Future Developments brings forth contemporary issues in the study of marine environments. The scope of the series includes ecological, toxicological and biological aspects of the topic. Each volume of the series focuses on a broad theme, with reviews contributed by several experts in the field. The series is essential reading for environmental scientists, ecologists, conservationists and marine biologists.

Download or read book Ecotoxicology of Antifouling Biocides written by Takaomi Arai and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organotin compounds, used as antifouling biocides since 1960, are chemical compounds that act as endocrine disrupters. It is not known how organotin compounds cause hormone disturbance, however, and many questions remain about their effect on aquatic organisms. Studies on organotin compounds have recently evolved, with many new findings reported. Following a worldwide ban on organotin compounds in 2008, alternative compounds will mainly be used, with the potential for coastal areas to become contaminated, causing, among other effects, cholinesterase inhibition in aquatic organisms. Use of alternative compounds must be controlled to avoid such errors. These and other findings are described and concisely summarized in this book, providing a useful reference in countries where alternative biocides are being considered. Included are studies on the effects on marine organisms, making this book an excellent aid to experts in environmental chemistry, to government organizations, and to students.

Download or read book Oil Spill Response in the Marine Environment written by J.W. Doerffer and published by Elsevier. This book was released on 2013-10-22 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid economic development of many countries since World War II has resulted in a considerable increase in the marine transport of raw materials, especially of crude oils, and in offshore activities. Inevitably, operational discharges from ships (ballast and bilge water), incidents such as collisions and groundings, and offshore exploration of oil and gas, lead to a significant amount of oil going into the sea. So far, understanding of marine environments, of oil and its behaviour when released onto the water surface, and of the methods and means of response to an oil spill, has been rather limited. This book introduces the reader to these problems and reflects the levels and trends of development in the field. The author has played an active role in combating marine pollution in the international arena since the 1970s and was awarded the International Maritime Prize for 1989 by the International Maritime Organisation.

Available in PDF, EPUB and Kindle. Book excerpt: L'accès des navires aux zones portuaires est assuré par le dragage de quantités importantes de sédiments. Les matériaux dragués ne peuvent être immergés que s'ils présentent toutes les garanties d'innocuité pour le milieu marin. Après un rappel sur la géochimie et la toxicité des différents contaminants qui sont adsorbés sur les sédiments, le présent ouvrage propose une approche globale de l'évaluation des risques environnementaux liés aux immersions. Les méthodes de caractérisation des risques à partir de l'analyse chimique (Géodrisk) et de tests de toxicité sélectionnés, de bioévaluation de la qualité des sédiments par la définition d'un Indice d'évaluation de l'endofaune côtière (I2EC) et de biomonitoring actif des zones d'immersion, sont décrites de manière détaillée. Cette démarche ascendante et itérative, appliquée au contexte réglementaire français, permet de satisfaire aux recommandations des conventions internationales et en particulier aux lignes directrices OSPAR.
