This book was released on 2018-02-09 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Exposure of Marine Birds to Environmental Pollutants Lethal and reproductive effects of organochlorines on marine birds have been most pronounced in coastal areas receiving effluents discharged by manufacturing plants. For example, particularly severe ddt contamination in southern California and elevated levels of dieldrin and related chemicals in the Netherlands have killed local marine birds or inhibited their reproduction. Eggshell thinning, apparently resulting from exposure to dde, is widespread among estuarine species, and eggshells of peregrine falcons (falco peregrinus) have become thinner in all areas of the species' range thus far studied. In more contaminated coastal areas, reproductive success of the peregrine falcon is low. Adverse effects of organochlorines on the reproduction of other species also have been found. The oiling of feathers and the associated mortality of marine birds are not the only adverse effects of oil pollution; ingestion of oil may cause death by dehydration by interfering with ion transport and water balance in the gut. Surfactants used to disperse oil spills also have serious consequences for ma rine birds. Dissolved oil fractions may kill or poison the biota the birds feed on. The physiological effects of the incorporation of more persistent com pounds into marine food webs are unknown.

Download or read book Environmental Pollutants and Eggshell Thickness written by Harry M. Ohlendorf and published by . This book was released on 1979 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1972 and 1973 we collected 1,339 clutches of eggs of anhingas (Anhinga anhinga) and 17 species of waders (herons, egrets, bitterns, ibises, and storks). We analyzed the eggs for organochlorine residues and compared shell thickness of these eggs and others collected since 1946 (and now in museum collections) with shell thickness of eggs collected before the widespread use of organochlorine pesticides. Eggshells were significantly thinner in one or more regions for the post-1946 samples of anhinga, great blue heron, black-crowned night heron, and wood stork. We detected no significant change in the other species.

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.
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.
Download or read book Environmental Contaminants in Wildlife written by James P. Meador and published by CRC Press. This book was released on 1996-03-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have been written about the effects of toxic chemicals on wildlife, but none has focused on the practical question, "How much of a chemical in the tissues of an animal is harmful?" This book deals exclusively with that question. This comprehensive reference will certainly become the standard resource on the topic, offering authoritative and sound advice on many environmental contaminants. With chapters written by outstanding experts in their respective fields, this is not only a scholarly collection of discussions on different chemicals, but, for those who have the day-to-day task of evaluating the harm of environment contaminants to wildlife, this book will provide answers on, for example, how to interpret 1 ppm lead in the liver of a duck or fish. The authors explain the snags of interpreting data that are sometimes conflicting or insufficient, providing the reader with helpful advice on how to cope with such data. Each chapter reviews literature on a specific chemical, followed by a easy-to-understand summary providing technical guidance. For many years this book will remain the preeminent reference on how to interpret contaminant levels of organochlorine pesticides, PCBs, dioxins, PAHs, metals, selenium, and fluorides in wildlife.

Download or read book Organochlorine Residues in Eggs of Alaskan Seabirds written by and published by . This book was released on 1982 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: One egg from each of 440 clutches of eggs of 19 species of Alaskan seabirds collected in 1973-76 was analyzed for organochlorine residues. Both frequency of occurrence and concentration of residues in the eggs differed geographically and by species, apparently reflecting non-uniform distribution of organochlorines in the environment, dissimilar feeding habits and migration patterns of the species, or metabolic differences among the species.
