Download or read book Endocrine Disrupters in Wastewater and Sludge Treatment Processes written by J. W. Birkett and published by IWA Publishing. This book was released on 2002-12-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocrine Disrupting Chemicals (EDCs) have been shown to produce changes in the endocrine system of organisms that lead to increases in cancers and abnormalities in reproductive structure and function. Recent research has highlighted the existence of hormonally active compounds in sewage and industrial effluents and their potential for recycling back into the environment - including drinking water supplies- through point sources and non-point sources. Endocrine Disrupters in Wastewater and Sludge Treatment Processes presents the latest research on EDCs, covering the sources, fate, and transport of EDCs in sewage and industrial effluents, and sludge treatment and disposal options in light of effects on receiving environments. In addition, the authors review current legislation, future research needs, and potential management strategies for endocrine disrupters in the environment.
Download or read book Synthesis of 4 tert octylphenoxyacetic Acid and Its Determination in Canadian Sewage Treatment Plant Effluents written by Hing-Biu Lee and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Residues of non-ionic surfactants such as alkylphenol ethoxylates and their metabolites in the environment have become a concern of late. These residues, readily found in the municipal sewage treatment plant effluents, are not only toxic to certain aquatic organisms but also weakly estrogenic and behave as endocrine disrupters. This report describes the synthesis of a metabolite of 4-tert-octylphenol ethoxylates and its determination in sewage effluents. This research supplement our current work on the assessment of the occurrence, fate and pathway of nonylphenol ethoxylates (a PSL 2 substance) in the Canadian environment"--Management perspective.
Download or read book Sample Preparation for Hyphenated Analytical Techniques written by Jack Rosenfeld and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linking “standard” but often mutually incompatible analytical techniques – so called hyphenation – generally leads to enhanced analytical performance, so hyphenated techniques are widely used in areas where samples are presented in complex matrices, eg environmental, pharmaceutical and biochemical analysis. With these hyphenated techniques, sample preparation is often the most time-consuming step in analysis, particularly where compounds are present in low concentration, and it has a huge influence on the quality of the analytical results. Sample preparation is still not given the importance it deserves, however. The purpose of this book is to demonstrate the sample preparation chemistry that has enabled the present sensitivity, specificity and high throughput available across a range of hyphenated analytical techniques, and to illustrate the successful utilization of existing sample preparation methodologies in various analytical applications. It identifies the problems in biology, environmental science and pharmaceutical chemistry that require new ideas in chemistry and provides considered opinion on those newer techniques that may address these problems. By dealing with wider issues than is generally found in review papers, this book will provide analytical chemists with insights that are not available by searching the literature for papers on a specific topic.

National Guidelines and Standards Office and published by National Guidelines and Standards Office. This book was released on 2002 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonylphenyl (NP) and NP ethoxylates (NPEs) are a group of organic chemicals that are widely used as surfactants, emulsifiers, wetting agents, and dispersants in a wide variety of industrial processes & commercial products. This document provides the rationale for development of Canadian environmental quality guidelines for NP & NPEs. It contains technical background information on the chemical & physical properties of NP & NPEs and a review of their sources & emissions in Canada, the distribution & behaviour of these chemicals in the environment, their toxicological effects on aquatic & terrestrial species, and NP/NPE guidelines developed in other jurisdictions. The information is then used to derive water, sediment, & soil quality guidelines for NP/NPEs to protect ecological receptors in each of these environmental compartments. The final sections suggest areas for future research & provide guidance on implementation of the guidelines.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
