Download or read book Proficiency Testing for All Fiber Sizes in Drinking Water written by Laurie J. Carhart and published by . This book was released on 1999 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Laboratory Approval Program (ELAP) of the New York State Department of Health has administered a proficiency-testing (PT) program for asbestos in drinking water since 1992. While the United States Environmental Protection Agency requires that only fibers longer than 10 ?m be counted, ELAP continues to require that all fibers longer than 0.5 ?m be analyzed. ELAP mandates the use of polycarbonate filters because short fibers are apparently lost in mixed-cellulose ester filters. Thirteen different waterborne asbestos samples have been distributed to approximately two to three dozen laboratories analyzing asbestos by transmission electron microscopy. Mean total fiber concentrations have ranged from 5.49 to 3340 million fibers per liter (MFL) while mean long (>10?m) fiber concentrations have ranged from 0.377 to 76.7 MFL. Failure rates have ranged from 3.5% to 21% of participating laboratories, with equivalent failure rates for total and long-fiber analyses. As laboratories gained experience in long-fiber analysis, they appeared to report results closer to consensus means.

This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book Encyclopedia of Environmental Analysis and Remediation Volume 1 written by Robert A. Meyers and published by Wiley-Interscience. This book was released on 1998-03-23 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedia is composed of an eight-volume set that provides an overview of the field of environmental analysis. The contents are divided into major content areas including air pollution control, environmental law, and environmental sampling. Thevolumes are organized alphabetically with each article signed by the author(s). The individual articles begin with a summary of the topic heading and then divide the text into subtopics indicated by boldface headings.The articles are written clearly, however, the authors assume a basic knowledge of chemistry and math on the part of the reader. For example, the acid mine drainage article refers to the Arrhenius equation, but does not clarify this statement in the text. Each article contains graphs as well as pictures to illustrate points made in the text. The articles are long and provide a detailed explanation of each topic. The authors also provide a bibliography at the end of each article.Special features of the encyclopedia include a list of contributors, a table of conversion factors and a list of abbreviations and acronyms. The preface outlines the general contents of the encyclopedia. The preface also includes sections that suggest the target audience and recommended usages for the set. The final volume of the set contains an alphabetic index to the topics contained in the volumes.
