This book was released on 2022-03-08 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: https://pub.norden.org/temanord2022-510/ Per- and polyfluoroalkyl substances (PFASs) are a large group of substances that have been widely used in articles since many years. They are found wherever extreme conditions prevail and particularly high demands are placed on materials. Their use spans over many different sectors ranging from fire-fighting foams to the manufacture of everyday articles like water-repellent outdoor jackets or stain-proofing agents.On the other side, PFASs are not easily degradable and can remain in the environment for decades. In addition, the use of PFASs has raised human and environmental concerns. In Europe, some PFASs are therefore classified as persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB) under the REACH Regulation. The following report provides an overview of currently available analytical methods for PFASs in different matrices.

This book was released on with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: https://pub.norden.org/temanord2024-510/ Per- and polyfluoroalkyl substances (PFAS) are a large group of substances that have been widely used for decades due to their surface-active properties. However, their characteristic resistance to degradation in combination with other properties of concern for human health and the environment has resulted in regulatory actions such as restrictions towards this group of substances, in the EU and globally. Compliance with restrictions as well as enforcement by authorities is key to reduce intentional use of restricted PFAS in articles and chemical products. To analyse PFAS accurately, robust and reliable analytical methods are required. This report evaluates the current situation related to PFAS-analyses and enforcement (including challenges and needs) and propose measures/strategies to enable and/or improve enforcement of, and compliance with current and future, PFAS restrictions.
Download or read book Environmental Sampling and Analysis written by Lawrence H. Keith and published by CRC Press. This book was released on 1991-03-18 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This concise book covers all the critical aspects of environmental sampling and analysis. Extensively peer-reviewed by scientists from the U.S. Environmental Protection Agency and other government agencies, industry and academia, it is packed with practical advice and tips from renowned experts. Planning, sampling, analysis, QA/QC, and reporting are discussed for air, water, solid liquid, and biological samples, with emphasis on the interdependence between sampling and analytical activities. Special requirements for sampling devices, containers, and preservatives are provided with convenient checklists for sampling plans and protocols. New and revised recommendations involving method detection levels, reliable detection levels, and levels of quantitation are discussed in conjunction with laboratory reports and user presentations of data near analytical detection limits. This is a valuable and comprehensive reference book for chemists, technicians, consultants, lawyers, regulators, engineers, quality control officers, news and information managers, teachers, and students.
Download or read book Guide to Environmental Analytical Methods written by Robert E. Wagner and published by . This book was released on 1992 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide condenses the information used most often from major environmental documentation such as SW-846; EPA 200, 500, and 600 Series; Standard Methods; and the Contract Laboratory Program (CLP) into one reference. The tabular approach effectively summarizes the key information (differences and similarities) of the most frequently referenced analytical methods. Included are method detection limits, calibration techniques, quality control requirements, analytes covered, sample storage, sample preservation, instrumentation, field sampling requirements, and other key parameters. There is also a compound cross-reference master list that allows the user to search for information by compound name. This table lists the methods in which the compound can be found, supplying an easy route for method selection. Quality assurance/quality control tables from the original methods have been included in the Appendix along with vital EPA regional information and a glossary of common terms and abbreviations.

Download or read book Sampling and Sample Preparation written by Markus Stoeppler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significant progress achieved in modern instrumental analysis has led to a continuous lowering of detection limits and improved precision. This should in principle permit the reliable and extremely precise analysis of trace compounds mainly trace elements, at levels down to the lowest natural concentrations. However, the frequently observed very high discrepancies between the analyt ical results of different laboratories as well as the deviations from true values are, regrettably, still common in analytical practice. Basic methodological errors at the determination step can usually be minimized or even avoided by carefully per formed quality control measures - e. g. by interlaboratory comparisons and the proper use of certified reference materials. The most severe and often under estimated error sources, however, are those connected with the whole and often extremely complex sampling process, and also to a lesser extent, with sample pre paration prior to analysis. Thus, for these initial steps of an analytical procedure particular experience is needed, as well as a detailed knowledge of the interrela tions between these steps, which always have to be applied with the utmost care. In collaboration with a number of very experienced colleagues working in dif book has tried to contribute to a better ferent research areas, the editor of this understanding of these particular error sources and how they can be overcome in a series of training courses held during the last decade at the "Haus der Technik", Essen, Germany.

Download or read book Valid Analytical Methods and Procedures written by Christopher Burgess and published by . This book was released on 2000 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Analytical Methods Committee of the Royal Society of Chemistry has for many years been involved in national and international efforts to establish a comprehensive framework for achieving appropriate quality in chemical measurement.This handbook attempts to select or define robust procedures that ensure the best use of resources and enable laboratories to generate consistent, reliable data. Written in concise, easy-to-read language and illustrated with worked examples, it is a guide to current best practice and establishes a control framework for the development and validation of laboratory-based analytical methods. Topics include samples and sampling, method selection, equipment calibration and qualification, method development and validation, evaluation of data and statistical approaches for method performance and comparison. Valid Analytical Methods and Procedures will be welcomed by many organisations throughout the world who are required to prove that the validity of their analytical results can be established beyond reasonable doubt.
