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.

Download or read book PFASs in the Nordic environment written by Anna Kärrman and published by Nordic Council of Ministers. This book was released on 2019-03-15 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a screening study of in all ninety-nine conventional and emerging per- and polyfluoroalkyl substances (PFASs) in the Nordic environment. In addition, extractable organic fluorine (EOF) was analysed. The latter can provide the amount, but not identity, of organofluorine in the samples, which in turn can be used to assess the mass balance between known and unknown PFASs. The study was initiated by the Nordic Screening Group and funded by these and the Nordic Council of Ministers through the Chemicals Group.A total of 102 samples were analyzed in this study, including bird eggs, fish, marine mammals, terrestrial mammals, surface water, WWTP effluents and sludge, and air. Samples were collected by institutes from the participating countries and self-governing areas; Denmark, Faroe Islands, Finland, Greenland, Iceland, Norway, and Sweden.

Download or read book Polyfluorinated Chemicals and Transformation Products written by Thomas P. Knepper and published by Springer Science & Business Media. This book was released on 2011-09-21 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC) have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and identification of biotransformation products of PFCs are described. The sorption and leaching behavior of PFC in soil is also addressed in order to predict their fate in the environment. Several contributions discuss the monitoring of PFCs in European surface, ground and drinking waters, treatment options for PFC removal from drinking water, occurrence in food, and the human biomonitoring of PFCs.

Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.
Download or read book Stabilisation Solidification of Contaminated Soil and Waste written by Colin Hills and published by . This book was released on 2015-10 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stabilisation/Solidification of Contaminated Soil and Waste comprises 2 handbooks designed to provide students, practitioners, site owners, and regulators with authoritative guidance to the science underpinning this versatile remedial technology, and how it is applied in real-world situations. Stabilisation/Solidification (S/S) uses readily available cementitious binders to turn contaminated soil and waste into a rock-like product that reduces the risk to public health and the environment. S/S has been employed at hundreds of sites in the USA, Canada, and Europe to improve the physical and/or chemical properties of contaminated soil and waste to enable development to take place or to safely manage a source of pollution. Science: Examines soil properties and the soil-binder system along with the scientific basis for immobilizing inorganic and organic contaminants. The long-term viability of S/S treatment is discussed with reference to the maintenance of design performance and groundwater quality. Practice: Describes how S/S is designed and implemented, including discussions on risk reduction, the development of performance specifications, available binders, treatability studies, in-situ and ex-situ equipment/operations, quality assurance, capping, site closure including long term monitoring strategies. The extensive appendices include a list of over 200 completed S/S remedial actions and over 40 case studies. The most complete authoritative books on the subject written in the last 20 years making them the definitive guide to S/S and still relevant in the 21st Century. Two volume set.
