Emerging Contaminants In Water Detection And Treatment Volume 2

Emerging contaminants refer to the naturally occurring or synthetic chemicals or substances that have been identified recently and are toxic to human health and environment. These are known as contaminants of emerging concern (CECs). Some major sources of CECs are pharmaceuticals and personal care products, detergents, steroid hormones, industrial chemicals, and pesticides. The complete removal of the CECs requires the use of advanced chemical, physical and biological treatment techniques. Advanced oxidation processes (AOPs) is an emerging chemical technology used for treating wastewater. Ozone, catalyst and UV irradiation are oxidants that combine in AOPs for delivering more efficient wastewater treatment. The CECs have demonstrated low acute toxicity but studies have shown that they may cause significant reproductive effects at low levels of exposure. This book outlines the latest methods for detecting and treating emerging contaminants in water and wastewater in detail. It will help the new readers in foregrounding their knowledge in this area of study.

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

The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.

This volume provides a collection of research findings on the distribution and risk associated with emerging contaminants (ECs) in water and wastewater across the globe, and effective remediation techniques and technologies. The book covers various monitoring techniques for ECs in water and wastewater and its related impacts on the ambient environment, and offers valuable information on cost-effective monitoring techniques and sustainable treatment technologies for ECs. The authors detail the risks and biological effects of ECs and legacy persistent organic pollutants (POPs) in freshwater and marine systems, including their adverse interactions with aquatic organisms, while also discussing the associated impacts on human health. The book comprehensively covers current research outcomes on treatment methods, cost-effectiveness, and infrastructure needs for effective removal of ECs. It will be of interest to students, researchers, and scholars in environmental science and engineering, water and wastewater, toxicology, environmental biotechnology, soil sciences, and microbial ecology.

With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLsâ€"produced every five yearsâ€"include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).

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

Contaminants of emerging concern in water are an ongoing challenge globally. This Special Issue is devoted solely to emerging contaminants in water. Research papers in this Special Issue address sampling and analysis, treatment effectiveness, and regulation to limit human exposure. Emerging contaminants addressed include pharmaceuticals and personal care products, glyphosate, microplastics and nanoplastics, venlafaxine, and benzodiazepine. Regulation of emerging contaminants in drinking water is reviewed focusing on PFOA and PFOS.
