Aquatic Contamination

In the early 1980s, two water-supply systems on the Marine Corps Base Camp Lejeune in North Carolina were found to be contaminated with the industrial solvents trichloroethylene (TCE) and perchloroethylene (PCE). The water systems were supplied by the Tarawa Terrace and Hadnot Point watertreatment plants, which served enlisted-family housing, barracks for unmarried service personnel, base administrative offices, schools, and recreational areas. The Hadnot Point water system also served the base hospital and an industrial area and supplied water to housing on the Holcomb Boulevard water system (full-time until 1972 and periodically thereafter). This book examines what is known about the contamination of the water supplies at Camp Lejeune and whether the contamination can be linked to any adverse health outcomes in former residents and workers at the base.

This second edition of Microplastic Contamination in Aquatic Environments: An Emerging Matter of Environmental Urgency presents 14 chapters, through which a team of global, expert contributors cover a full range of microplastic research. The first chapter describes the general patterns for sources, occurrence, and transport of microplastics to lead off the book. The next batch of chapters covers sampling analytical methods for quantifying microplastics in the environment, followed by chapters addressing the association of chemicals with microplastics. A large cluster of chapters focus on the fate and transport of microplastics in wastewater treatment plants, freshwater systems, marine environment, terrestrial settings, and riverine runoff that connects terrestrial and marine systems. The next few chapters examine biotransport and effects of microplastics in organisms. The last two chapters are dedicated to two emerging research areas: nanoplastics in the environment and management strategies for global plastic pollution. Outlooks for future research to better understand the situation and further improvements of microplastic research are also covered. In the 6 years since the previous edition published, this fast-moving area has evolved, and the contents of this revision reflect that. There are numerous brand-new chapters, chapters that have been revised, and chapters that have been completely refocused. This book provides an overview of microplastics research. It is a guide for researchers to better understand the occurrence of microplastics. Ideally, this book provides basic background knowledge of microplastics for oceanographers, ecologists, and climatologists. Provides an overview of the advantages and disadvantages of different methods for sampling, identification, and enumeration of microplastics Contains contributions from world experts with a diverse range of backgrounds, all brought together by a well-known, experienced editor Presents information on microplastics in a unified place, with easy access for the reader

This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Water containing significant amounts of inorganic and organic contaminants can have serious environmental consequences and serious health implications when ingested. Contamination of Water: Health Risk Assessment and Treatment Strategies takes an interconnected look at the various pollutants, the source of contamination, the effects of contamination on aquatic ecosystems and human health, and what the potential mitigation strategies are. This book is organized into three sections. The first section examines the sources of potential contamination. This includes considering the current scenario of heavy metal and pesticide contamination in water as well as the regions impacted due to industrialization, mining, or urbanization. The second section goes on to discuss water contamination and health risks caused by toxic elements, radiological contaminants, microplastics and nanoparticles, and pharmaceutical and personal care products. This book concludes with a section exploring efficient low-cost treatment technologies and remediation strategies that remove toxic pollutants from water. Contamination of Water incorporates both theoretical and practical information that will be useful for researchers, professors, graduate students, and professionals working on water contamination, environmental and health impacts, and the management and treatment of water resources. Provides practical case studies of various types and sources of contamination Discusses inorganic and organic contaminants and their impact on human health Evaluates effective water treatment and remediation technologies to remove toxins from water and minimize risk

Soil and Water Contamination, Second Edition gives a structured overview of transport and fate processes of environmental contaminants. Providing a structured overview of transport and fate processes of environmental contaminants, this textbook approaches the environmental issues of soil and water contamination from a spatial and earth science point of view. The new edition contains new material on pesticides and pharmaceutical contaminants and a greater number of exercises, case studies, and examples. It covers topics essential to understanding and predicting contaminant patterns in soil, groundwater, and surface water and contributes to the formation of a solid basis for adequate management and control of soil and water pollution and integrated catchment.

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.

Aquatic Contamination Authoritative resource presenting techniques and technologies to sustainably neutralize environmental contamination in aquatic plants, microorganisms, and more Two thirds of the Earth is covered with aquatic habitats that play a key role in stabilizing the global environment and providing a wide variety of services to increasing human needs. Nevertheless, anthropogenic activities are rapidly destroying the quality of both fresh and marine waters globally, due to excessive use of chemicals, fertilizers and pollution from suburban and industrial areas eventually making their way into the aquatic world. Aquatic Contamination: Tolerance and Bioremediation presents the broader spectrum of biological applicability of microbes with better understanding of cellular mechanisms for remediation of aquatic contaminants. The book also focuses on practices involved in molecular and genetic approaches, necessary to achieve targets of bioremediation and phytoremediation to solve global water contamination problems. Such approaches pave the way for the utilization of biological assets to design new, efficient, and environmentally sound remediation strategies by inculcating genomic techniques at cellular and molecular levels with model assessment. Aquatic Contamination provides a comprehensive background for readers interested in all perspectives of the contamination of aquatic environs. It covers various research aspects which are being carried out globally to understand simulation models in the assessment of xenobiotics, role of genomics, transgenic plants, and microbial enzymes for degradation and removal of toxic substances in aquatic environs. Key features include: Extensive coverage of interactions between plants, metals and microbes including the influence of biotic and abiotic factors Comprehensive discussion of the details of molecular mechanisms from assimilation to detoxification levels Exploration of the enzymatic approaches of potential plants acting as hyper-accumulators for contaminants in aquatic environs Details of sustainable tools such as transgenic plants for the manipulation of important functional microbial genes to achieve higher certainty of bioremediation Details of advances in tools and models like micro-arrays and simulation models for the complete assessment of xenobiotic compounds from cellular to degradation hierarchies Aquatic Contamination: Tolerance and Bioremediation will be substantially helpful to environmentalists, microbiologists, biotechnologists and scientists, providing essential information on various modern technologies for the remediation of contaminants in aquatic ecosystems.

In aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors’ experience, of a number of current issues which have been raised in the literature.
