An understanding of the fate and behaviour of organic chemicals, such as surfactants, in the environment is a prerequisite for the sustainable development of human health and ecosystems. As surfactants are being produced in huge amounts, it is important to have a detailed knowledge about their lifetime in the environment, their biodegradability in wastewater treatment plants and in natural waters, and their ecotoxicity. Parameters relevant for the assessment of long-term behaviour, such as interactions with hormonal systems need to be understood to avoid unexpected adverse effects to future generations of people and the environment. However, the identification and quantification of commercial surfactants in the environment is made more complicated and cumbersome because they comprise of tens to hundreds of homologues, oligomers and isomers of anionic, nonionic, cationic and amphoteric compounds.The EU-funded PRISTINE project (Priority surfactants and their toxic metabolites in wastewater effluents: An integrated study; ENV4-CT97-0494) provides the basis for the content of this title. It provides policy makers and industry with detailed information on analysis and concentrations of surfactants and their degradation products in the environment.In addition to a general introduction to surfactants, this book comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment. Readers will find all the necessary information for analyzing the different groups of surfactants, with special emphasis on transformation products. Quality assurance is also reported on in detail. Chapters on toxicity and risk assessment are also included and give a complete perspective on the surfactants problem in the aquatic environment.·Presents the finding of EU-funded research into fate and behaviour of organic chemicals in the environment·Comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment·Provides relevant information to all groups working in the field of surfactants

There may be nearly 300,000 waste sites in the United States where ground water and soil are contaminated. Yet recent studies question whether existing technologies can restore contaminated ground water to drinking water standards, which is the goal for most sites and the result expected by the public. How can the nation balance public health, technological realities, and cost when addressing ground water cleanup? This new volume offers specific conclusions, outlines research needs, and recommends policies that are technologically sound while still protecting health and the environment. Authored by the top experts from industry and academia, this volume: Examines how the physical, chemical, and biological characteristics of the subsurface environment, as well as the properties of contaminants, complicate the cleanup task. Reviews the limitations of widely used conventional pump-and-treat cleanup systems, including detailed case studies. Evaluates a range of innovative cleanup technologies and the barriers to their full implementation. Presents specific recommendations for policies and practices in evaluating contamination sites, in choosing remediation technologies, and in setting appropriate cleanup goals.

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.

Metal Organic Frameworks for Wastewater Contaminant Removal Discover a groundbreaking new wastewater decontamination technology The removal of wastewater contaminants is a key aspect of the water cycle, allowing water to be fed safely back into circulation within a given ecosystem. Metal-Organic Frameworks (MOFs) are a new class of porous materials which can reversibly bind and sequester both metal ions and potentially harmful organic substances, giving them a potentially crucial role in the targeted removal of wastewater contaminants. They may also enable significant cost and energy savings over now-conventional ion exchangers in water treatment plants. Metal Organic Frameworks for Wastewater Contaminant Removal provides an accessible, practical guide to the development, evaluation, and potential applications of MOFs in maintaining the water cycle. It begins with an overview of the major metallic and non-metallic contaminants found in wastewater and their interactions with major MOF-based materials, before moving to the challenges and opportunities provided by MOFs in the pursuit of a sustainable, energy-efficient water cycle. The result is a groundbreaking resource in the ever-expanding global fight to keep water clean and safe. Metal Organic Frameworks for Wastewater Contaminant Removal readers will also find: MOF technology and its water treatment applications discussed in depth for the first time in a major publication Comparison with existing decontamination technologies and environmental risk assessment Applications for environmental as well as industrial toxicants based on recent research and on case studies Metal Organic Frameworks for Wastewater Contaminant Removal is indispensable for water chemists, chemical engineers, environmental chemists, and for any researchers or industry professionals working with water decontamination technologies.
