Contaminants Of Emerging Concern In The Marine Environment

Contaminants of emerging concern in the marine environment: current challenges in marine pollution reviews the available data in relation to contaminants of emerging concern (CECs) in the marine environment: main sources, transport pathways, distribution in seawater and sediments, bioaccumulation, and biological effects. Each chapter recaps the most relevant information about the main groups of CECs, describing the particularities and specificities of each group and focusing on the most relevant individual contaminants. CECs are not regulated substances, and therefore not considered in national and international monitoring programs, even though they may have a potential impact on the environment due to their continuous input, relative persistence, and/or toxicity. CECs are relevant not only in continental and coastal areas close to their main sources, but also in the open sea, because some of them are likely to be transported long distances through air deposition or absorbed into particulate material. The persistence of many degradable substances in the marine environment increases when they are absorbed into particulate material/sediments and/or when they are subjected to anaerobic conditions that slow down the degradation kinetic of many contaminants. Bioaccumulation of several CECs has been confirmed in different coastal organisms; however, in general, the information available (species and trophic levels considered) is very limited because most studies are mainly focused on specific coastal areas. This book offers useful information about not regulated contaminants that are not considered in international monitoring programs but have potential impacts in coastal and open-sea areas. Therefore reading the book will allow them to improve their view about the real impact of current-use contaminants in the marine environment. Presents a comprehensive view of the most relevant groups of CECs Includes an overview of each group of CECs, including uses, properties, analysis, distribution, bioaccumulation, and effects Provides information on all environmental compartments and marine areas (coast, continental shelf, and open sea)

Management of Contaminants of Emerging Concern (CEC) in Environment provides information about new concepts and latest developments in origin, reaction pathways, transportation, transformation products, identification, and adverse effects of CEC, as well as recent remediation technologies and tools for CEC. The book explores processes such as nanotechnology for the degradation of CEC by using various heterogeneous catalysts. The chapters incorporate both theoretical and practical aspects and can serve as a baseline for future studies. So, Management of Contaminants of Emerging Concern (CEC) in Environment is an indispensable resource for university students, teachers, and researchers, especially those working in the area of remediation and management of contaminants of emerging concern. Takes a holistic approach, focusing on the origin of contaminants, type of contaminants, remediation technologies, regulations and legal aspects Applies chemical, physical and biological processes for the treatment of emerging contaminants Written by a team of internationally reputed and rising researchers

Emerging Contaminants in the Environment: Challenges and Sustainable Practices covers all aspects of emerging contaminants in the environment, from basic understanding to different types of emerging contaminants and how these threaten organisms, their environmental fate studies, detection methods, and sustainable practices of dealing with contaminants. Emerging contaminant remediation is a pressing need due to the ever-increasing pollution in the environment, and it has gained a lot of scientific and public attention due to its high effectiveness and sustainability. The discussions in the book on the bioremediation of these contaminants are covered from the perspective of proven technologies and practices through case studies and real-world data. One of the main benefits of this book is that it summarizes future challenges and sustainable solutions. It can, therefore, become an effective guide to the elimination (through sustainable practices) of emerging contaminants. At the back of these explorations on sustainable bioremediation of emerging contaminants lies the set of 17 goals articulated by the United Nations in its 2030 Agenda for Sustainable Development, adopted by all its member states. This book provides academics, researchers, students, and practitioners interested in the detection and elimination of emerging contaminants from the environment, with the latest advances by leading experts in emerging contaminants the field of environmental sciences. Covers most aspects of the most predominant emerging contaminants in the environment, including in soil, air, and water Describes the occurrence of these contaminants, the problems they cause, and the sustainable practices to deal with the contaminants Includes data from case studies to provide real-world examples of sustainable practices and emerging contaminant remediation

This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

There is growing concern about the state of the world's oceans. The rapid growth of human populations in coastal regions has led to increasing dependence on marine resources. Beneficial features related to food supply and life style need to be balanced against the hazards presented by microbial pathogens, chemical pollutants, and toxic algal blooms. In this book, a group of experts from a range of backgrounds review the key aspects of the marine environment in relation to human health. An initial overview explains the need for integrating a range of disciplines, from physical oceanography and marine biology to molecular biology and epidemiology. Only by this approach can we hope to predict the consequences of environmental change and exploitation of natural resources upon our coastal ecosystems and, ultimately, on society and human health. Subsequent chapters then focus on more specialized topics. Firstly, waterborne pathogens are reviewed in detail and the microbial measures and policy implications important for protecting humans from exposure are described. Next, the consumption of contaminated seafood is considered along with its implications regarding the growth of aquaculture. Priority pollutants, emerging contaminants, and plastics are investigated as are the effects of climate change on pollution. Some phytoplankton produce biotoxins which accumulate in the flesh of filter-feeders such as bivalve molluscs. This creates a health risk when the shellfish are consumed by humans. The penultimate chapter, therefore, concentrates on harmful algal blooms (HABs) and the methodologies used to safeguard human health. The book concludes by proposing a holistic systems approach, such as Integrated Coastal Zone Management, to address the interconnected scientific challenges of increased human population pressure, pollution, over-exploitation of food resources, and the urgent need for effective public health solutions to be developed from politically and environmentally meaningful policies.
