Beskrivning

The formation, control, and health effects of DBPs in drinking water are issues of international concern because of the health effects (e.g., bladder cancer and potential adverse reproductive-development impacts) associated with exposure to certain DBPs. As a result, many countries, as well as the World Health Organization, have regulations and/or guidelines on acceptable concentrations of DBPs in water.In recent years, DBP research worldwide has focused on determining the possible adverse health effects of emerging, yet unregulated, DBPs, specifically halogenated (e.g., iodinated) and non-halogenated nitrogenous (e.g., nitrosamines) DBPs. The breadth of DBP research is very broad from source waters (e.g., wastewater, wildfire, seawater intrusion influences) to treatment strategies and technologies, followed by distribution system and point of entry issues (e.g., biofilms, heating, swimmingpools), as well as health effects and analytical method developments. Recent research is helping to understand factors controlling formation and to develop a cost-effective control of a wide range of regulated and emerging DBPs. Furthermore, the pace of research on emerging DBP toxicity has increasedand generated diverse findings, with comparative toxicity and the molecular mechanisms leading to improved understanding of their toxicity pathways and potential adverse biological effects.This book represents the latest research efforts to understanding these important DBP-related issues. The authors of the chapters in this book are a multidisciplinary group of scientists and engineers, who are conducting studies in many parts of the world. The chapters in this book address both regulated and emerging DBPs and are organized under the sections on DBP toxicology and health effects, modeling of DBP formation, precursors and reactions involving nitrosamines, and formation ofhalogenated DBPs. This book will be of interest to researchers, drinking water utility scientists and engineers, toxicologists, epidemiologists, and regulators interested in the formation and control of and exposure to DBPs.
