This book was released on 1999-09-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLsâ€"produced every five yearsâ€"include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).

Available in PDF, EPUB and Kindle. Book excerpt: Drinking water policies and research are intimately linked. It is thanks to the scientific progress made over the last 25 years in identifying and controlling toxic products in drinking water that regulations have developed in such a way that the protection of public health from waterborne diseases has drastically improved. The integration of research outputs into the policy-making progress requires close cooperation among the scientific and policy communities, which is not always straightforward. Exchanges among scientific and policy-making communities are certainly representing key elements of progress for a better environmental protection. In this respect, analytical developments linked to drinking water are at the core of the science-policy debate. This book "Analytical Methods for Drinking Water: Advances in Sampling and Analysis" reflects this awareness in joining recent analytical developments with policy considerations. A first chapter gives an overview of EU and US drinking water policies, as well as on standardization. Analytical developments are described in depth in the second chapter, focusing on bromate in drinking water. The third chapter deals with the development of a sampling protocol for lead in drinking water, thus mixing analytical development with standardization needs. Finally, the fourth chapter focuses on standardization aspects (pre-normative research) related to materials in contact with drinking water. This book, written by experts in the field of drinking water policy and analysis, illustrates recent scientific advances in this area, which have contributed to policy development and will be of direct use to policy-makers, water scientists, researchers and analytical laboratories.

Download or read book Sample Handling and Trace Analysis of Pollutants written by Damia Barcelo and published by Elsevier. This book was released on 2000-03-08 with total page 1151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an updated, completely revised version of a previous volume in this series entitled: ENVIRONMENTAL ANALYSIS -- Techniques, applications and quality assurance. The book treats different aspects of environmental analysis such as sample handling and analytical techniques, the applications to trace analysis of pollutants (mainly organic compounds), and quality assurance aspects, including the use of certified reference materials for the quality control of the whole analytical process. New analytical techniques are presented that have been developed significantly over the last 6 years, like solid phase microextraction, microwave-assisted extraction, liquid chromatography-mass spectrometric methods, immunoassays, and biosensors. The book is divided into four sections. The first describes field sampling techniques and sample preparation in environmental matrices: water, soil, sediment and biota. The second section covers the application areas which are either based on techniques, like the use of gas chromatography-atomic emission detection, immunoassays, or coupled-column liquid chromatography, or on specific application areas, like chlorinated compounds, pesticides, phenols, mycotoxins, phytotoxins, radionuclides, industrial effluents and wastes, including mine waste. Validation and quality assurance are described in the third section, together with the interpretation of environmental data using advanced chemometric techniques. The final section reports the use of somewhat advanced analytical methods, usually more expensive, less routinely used or less developed, for the determination of pollutants.

Download or read book Analytical Method Development for Measurement of Unregulated Organic Contaminants in Aqueous Samples Using Liquid Chromatography - Tandem Mass Spectrometry written by Min Yoon and published by . This book was released on 2010 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic wastewater contaminants (OWCs) such as pharmaceuticals, hormones, and perfluorinated compounds (PFCs) are of growing environmental and public health concern. These OWCs were found in U.S. drinking water supplies according to nationwide studies by the U.S. Geological Survey. Many OWCs are not, however, regulated or routinely monitored in drinking water. The objective of this dissertation was to develop and optimize analytical methods for trace analysis of unregulated organic contaminants in drinking water sources. Furthermore, household water treatment-processes were studied to measure the efficacy of removal of these unregulated organic contaminants from drinking water samples. Two liquid chromatography-ion trap mass spectrometry systems (LC-IT-MS/MS) were compared for rapid, reliable and sensitive detection of the most abundant PFCs, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). An ultra performance LC-linear IT-MS/MS achieved the lowest detection limits measured, 0.03pg and 0.24pg for PFOA and PFOS respectively, which were approximately two orders of magnitude more sensitive than an LC-IT-MS/MS. With the increased sensitivity, the direct analysis of PFOA/S without solid phase extraction pre-concentration steps was also demonstrated. In addition, MS methods using Full Scan, Single Ion Monitoring, and MS/MS were compared and optimized for a sensitive analysis of PFCs. A novel rapid method was created by switching polarity for the simultaneous analysis of twenty unregulated compounds, including pharmaceuticals. Sensitive method detection limits were achieved in the range of sub ng/L to hundreds ng/L for all target compounds. An optimized analytical method was applied to quantify low ng/L levels of these target compounds in field water samples from regions throughout New Jersey. Eight target compounds were measured below 1℗æg/L and two target compounds (i.e. metformin and estradiol) were measured slightly above 1æg/L in the field water samples. Finally, granular activated carbon (GAC) and ion resin (Brita[trademark symbol]) filtration, ozonation, and microwave heating were tested for efficacy at removing 20 target compounds in drinking water samples. The GAC/ion resin mechanism with adsorption properties demonstrated greater removal of the target compounds than the other two mechanisms. Even this water treatment-process only partially removed these target compounds with its mean removal of [less than or equal to symbol] 66%.

Available in PDF, EPUB and Kindle. Book excerpt: Determination of subpart-per-billion (sub-ppb) levels of volatile organic compounds in the atmosphere by flame ionization gas chromatography requires sample sizes of at least several hundred milliters of air. Cryogenic methods of concentrating trace compounds before analysis have the disadvantage of also concentrating large amounts of water, a serious problem in gas-liquid chromatography. A simple method was developed for sample collection and concentration using porous polymer adsorbants with the unique properties of high capacity for retention of organic compounds and minimal capacity for retention of water. This technique was used to determine sub-ppb levels of volatile organic compounds in a typical rural atmosphere. Probable sources of these organic compounds were vehicle exhaust, biological processes, natural gas leaks, and industrial chemicals.
