Endocrine Disrupting Chemicals In Drinking Water

Examines the potential implications of endocrine disrupting compounds (EDCs) and pharmaceutically active compounds (PhACs) for drinking water and wastewater utilities. Based on an April 2000 workshop held in Chicago, the report overviews various perspectives on identifying and measuring compounds of interest, possible public health impacts, water treatment options, and risk perception and communication issues. The resulting research needs are outlined. An appendix provides abstracts of the lectures delivered. No index. c. Book News Inc.

Endocrine disrupting chemicals (EDCs) are contaminants of emerging environmental and health concern that have been detected in freshwater, wastewater and drinking water. They interfere with the endocrine system in humans and wildlife, and produce adverse effects such as developmental, reproductive, neurological and immune effects.

Endocrine disrupting chemicals (EDCs) are contaminants of emerging environmental and health concern that have been detected in freshwater, wastewater and drinking water. They interfere with the endocrine system in humans and wildlife, and produce adverse effects such as developmental, reproductive, neurological and immune effects. Their presence in water raises concerns for the integrity of ecosystems and biodiversity. Addressing the challenges of EDCs in water is particularly complex due to their ability to trigger adverse effects at very low concentrations, their potency in mixtures with other chemicals, and the vast range of sources and entryways of this group of chemicals into the environment. This report presents new water quality monitoring methods, such as bioassays and non-targeted analysis, that are well equipped to capture the impacts of EDCs in water. These new methods supplement the traditional substance-by-substance chemical analysis of water quality. The report also outlines policy instruments to manage the chemicals' lifecycle from source to end-of-pipe. It proposes tools and regulations that respond to the negative effects of endocrine disruption, even if the culprit chemical is still unknown. The analysis draws on case studies from OECD countries to provide practical examples and concrete policy actions.

Endocrine Disrupting Chemicals (EDCs) have been shown to produce changes in the endocrine system of organisms, leading to increases in cancers and abnormalities in reproductive structure and function. This book presents research on the endocrine-disrupting effects of sewage and industrial effluents, covering the sources, fate, and transport of EDCs

EDCs and pharmaceuticals are groups of emerging contaminants that have been detected at trace concentrations in waters around the world. These contaminants encompass a vast range of molecular structure and properties. Sparse data exist on the occurrence and fate of these emerging contaminants during water treatment. This project investigated EDC/pharmaceutical occurrence in U.S. drinking water and the efficacy of conventional and advanced water treatment processes to reduce the concentrations of these contaminants. The objectives of this study were to (1) select a diverse group of representative endocrine disrupting chemicals (EDCs) and pharmaceuticals, (2) develop a robust analytical methodology capable of trace detection of target compounds in a variety of water matrices, (3) determine the occurrence of target compounds in U.S. drinking waters, (4) evaluate the EDC/pharmaceutical removal potential of conventional and advanced drinking and reuse water processes, and (5) evaluate computer models to predict target compound properties and fate. This report provides fundamental information on the removal of several classes of pharmaceuticals, personal care products, and suspected endocrine disrupting chemicals by conventional and advanced water treatment processes. A detailed description of analytical methods is provided, including information on sample preservation, extraction, and instrumental analysis. The report provides some of the first U.S. occurrence data for these emerging contaminants in raw and finished drinking water supplies. From the treatment and occurrence information, compounds with likely occurrence can be selected for monitoring programs that will represent the fate of various classes of emerging contaminants. Computer models are described that can be used to predict properties and fate of future water contaminants.
