Endocrine Disruptors And Pharmaceuticals 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.

The detection of pharmaceutical residues remained elusive until instruments such as liquid chromatography and mass spectrometry became commonplace in environmental laboratories. The documentation of the occurrence of pharmaceutical residues and endocrine disrupting chemicals in water resources has raused questions about their long-term effects

Explains key chemicals from drugs and cosmetics in water and clarifies their risks Covers endocrine disruptors and other biologically active compounds Reviews EPA testing protocols for steroids and hormones This book surveys current knowledge regarding endocrine disruptors and other hormone-mimicking compounds in the environment as a result of the disposal of cosmetics, drugs, and cleaning agents. The book investigates dozens of biologically active pollutants, describes their physiological effects, and assesses the evidence of their impact on humans and wildlife. Substances treated include phthalates, bisphenol-A, hormones and an array of steroids. Techniques being investigated by the EPA for the detection and analysis of steroids and hormones in water samples are presented. This is a key reference volume for environmental health, risk assessment and water/wastewater technology.

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.

Endocrine disrupting chemicals (EDCs) and pharmaceuticals and personal care products (PPCPs) are groups of emerging contaminants that have been detected at trace concentrations in waters around the world. This project studies the monitoring and removal of various EDCs and PPCPs.
