This volume attempts to summarize the joint efforts of a group of workers who developed systems for analysing marine pollution for use with marine animals and then use these systems to monitor certain select marine populations. Approach taken is to seek pollutant-induced changes in metabolite (e.g. glutathione, ascorbate) concentrations, in hormone concentrations, in enzymes associated with pollutant metabolism (e.g. the cytochrome P-450 mixed-function oxidase system), in immunological capacity and in cellular morphology. The work reported here details the specific methods used and summarizes the results of measurement of the parameters in both pristine and exposed animals. Not all systems exhibited changes in response to the pollutants tested; these systems are also discussed here to help others avoid these potential, but insensitive, markers.

Marine Pollution: Sources, Fate and Effects of Pollutants in Coastal Ecosystems bring together the theoretical background on common and emerging marine pollutants and their effects on organisms (ecotoxicology). Written by a renowned expert in the field who is a researcher, teacher and advisor of national and international institutions on issues such as oil spills, water quality assessment and plastic pollution, this book offers a thorough account of the effects of pollutants on marine organisms, the relevant environmental regulations, and the public health implications, along with the biological tools advocated by the international institutions for marine pollution monitoring.Marine Pollution: Sources, Fate and Effects of Pollutants in Coastal Ecosystems presents information in a detailed and didactic manner, reviewing the latest scientific knowledge alongside examples of practical applications. Provides an in-depth analysis of the uptake, accumulation and fate of pollutants in the marine compartments Delivers a critical appraisal on biological tools for the practical monitoring of marine pollution Presents key concepts and case studies to provide a comprehensive study of the different categories of marine pollution and its effects

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.

Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.

Modern Treatment Strategies for Marine Pollution provides an overview of assessment tools that identify contaminants in marine water, also discussing the latest technologies for removing these contaminants. Through templated and consistently structured chapters, the author explores the importance of seawater to our marine ecosystems and the devastating effects pollutants are causing. Sections cover the emission of toxic pollutants from industries, wastewater discharge, oil spills from boarding ships, ballast water emission, abnormal growth of algal blooms, and more. Techniques explored include huge diameter pipelines erected for removing floating debris from seawater, which is denoted as a primary idea for cleaning contaminants. The book includes numerous case studies that demonstrate how these tools can be successfully used. It is an essential read for marine ecologists and oceanographers at the graduate level and above, but is also ideal for those looking to incorporate these techniques into their own work. - Presents and discusses advanced technologies used in the treatment of marine water - Includes case studies to show what techniques have been successful - Provides new information on contamination assessment and analytical protocols for identifying pollutants, which is essential for readers to use in their own work

Marine Ecotoxicology: Current Knowledge and Future Issues is the first unified resource to cover issues related to contamination, responses, and testing techniques of saltwater from a toxicological perspective. With its unprecedented focus on marine environments and logical chapter progression, this book is useful to graduate students, ecotoxicologists, risk assessors, and regulators involved or interested in marine waters. As human interaction with these environments increases, understanding of the pollutants and toxins introduced into the oceans becomes ever more critical, and this book builds a foundation of knowledge to assist scientists in studying, monitoring, and making decisions that affect both marine environments and human health. A team of world renowned experts provide detailed analyses of the most common contaminants in marine environments and explain the design and purpose of toxicity testing methods, while exploring the future of ecotoxicology studies in relation to the world's oceans. As the threat of increasing pollution in marine environments becomes an ever more tangible reality, Marine Ecotoxicology offers insights and guidance to mitigate that threat. - Provides practical tools and methods for assessing and monitoring the accumulation and effects of contaminants in marine environments - Unites world renowned experts in marine ecotoxicology to deliver thorough and diverse perspectives - Builds the foundation required for risk assessors and regulators to adequately assess and monitor the impact of pollution in marine environments - Offers helpful insights and guidance to graduate students, ecotoxicologists, risk assessors, and regulators interested in mitigating threats to marine waters

Aquatic Pollutants: Transformation and Biological Effects contains the proceedings of the Second International Symposium on Aquatic Pollutants held at Noordwijkerhout (Amsterdam), The Netherlands on September 26-28, 1977. Organized into 47 chapters, this book first describes the aquatic pollutants and their potential biological effects. Subsequent chapters elucidate chemicals with pollution potential; multidetection approach to analysis of organic pollutants in water; volatilization of pollutants from water; microbial transformations of aromatic pollutants; and photochemical transformation of pollutants in water. Other chapters address oxidation of organic compounds in aquatic systems; laboratory microcosms for use in determining pollutant stress; continuous biomonitoring systems for detection of toxic levels of water pollutants; and health aspects of water recycling practices. This book will be useful as a review of existing knowledge in this field. It will also stimulate further thought and research.
