Details the water research applications of nanotechnology in various areas including environmental science, remediation, membranes, nanomaterials, and water treatment At the nano size, materials often take on unique and sometimes unexpected properties that result in them being ‘tuned’ to build faster, lighter, stronger, and more efficient devices and systems, as well as creating new classes of materials. In water research, nanotechnology is applied to develop more cost-effective and high-performance water treatment systems, as well as to provide instant and continuous ways to monitor water quality. This volume presents an array of cutting-edge nanotechnology research in water applications including treatment, remediation, sensing, and pollution prevention. Nanotechnology applications for waste water research have significant impact in maintaining the long-term quality, availability, and viability of water. Regardless of the origin, such as municipal or industrial waste water, its remediation utilizing nanotechnology can not only be recycled and desalinized, but it can simultaneously detect biological and chemical contamination. Application of Nanotechnology in Water Research describes a broad area of nanotechnology and water research where membrane processes (nanofiltration, ultrafiltration, reverse osmosis, and nanoreactive membranes) are considered key components of advanced water purification and desalination technologies that remove, reduce, or neutralize water contaminants that threaten human health and/or ecosystem productivity and integrity. Various nanoparticles and nanomaterials that could be used in water remediation (zeolites, carbon nanotubes, self-assembled monolayer on mesoporous supports, biopolymers, single-enzyme nanoparticles, zero-valent iron nanoparticles, bimetallic iron nanoparticles, and nanoscale semiconductor photocatalysts) are discussed. The book also covers water-borne infectious diseases as well as water-borne pathogens, microbes, and toxicity approach.

Группа авторов Drinking Water Regulation and Health


The Drinking Water Act Amendments of 1996 instituted wide-ranging regulatory changes to the seminal Safe Drinking Water Act (SDWA)-such as providing funding to communities facing health risks, focusing regulatory efforts on contaminants posing such health risks, and adding flexibility to the regulatory process- and the amendments continue to shape regulations and regulatory policy to this day. Editor Frederick Pontius's Drinking Water Regulation and Health provides a comprehensive, up-to-date resource on the current regulatory landscape. Drinking Water Regulation and Health serves as a guide for water utilities, regulators, and consultants, forecasting future trends and explaining the latest developments in regulations. A diverse group of contributors covers topics such as water treatment, water protection, how some of the regulations have been interpreted in the courts, how water utilities can stay in compliance, and how to satisfy customer expectations, especially sensitive subpopulations. Divided into four sections – The SDWA and Public Health, Regulation Development, Contaminant Regulation and Treatment, and Compliance Challenges – the book includes chapters on: * Improving Waterborne Disease Surveillance * Application of Risk Assessments in Crafting Drinking Water Regulations * Control of Drinking Water Pathogens and Disinfection By-Products * Selection of Treatment Technology for SDWA Compliance * Death of the Silent Service: Meeting Consumer Expectations * Achieving Sustainable Water Systems * What Water Suppliers Need to Know About Toxic Tort Litigation

Группа авторов Partition and Adsorption of Organic Contaminants in Environmental Systems


Given the presence of a wide variety of contaminants in the environment, it is important to understand what drives a contaminant from one medium to another, as well as the manner and extent to which a contaminant associates with the different media or phases within a local environmental system. Partition and Adsorption of Organic Contaminants in Environmental Systems forms a comprehensive resource on the behavioral characteristics of contaminants so that appropriate strategies can be adopted to either prevent or minimize their adverse impacts on human welfare and natural resources. Cary Chiou’s far-reaching text depicts the processes by which nonionic organic contaminants are sorbed to natural biotic and abiotic substances. This book focuses on physical principles and system parameters that affect the contaminant uptake by soil from water, air, and other media; by fish from water; and by plants from soil and water. As contaminant uptake by natural organic substances is often predominantly a partition interaction, the partition characteristics in several solvent-water model mixtures are treated in detail to elucidate the relevant physicochemical parameters. The account of contaminant sorption to soils, fish, and plants is strengthened by companion chapters on: Fundamentals of solution theory Interphase partition equations Fundamentals of adsorption theory Vapor adsorption on mineral and carbonaceous solids No other single source in the field delivers as compelling a combination of background understanding and «state-of-the-science» comprehension of current issues. Ideally suited for a graduate-level environmental course, Partition and Adsorption of Organic Contaminants in Environmental Systems also serves as a technical guide to current and future research in the field.
