Analytical Methods For Pfas In Products And The Environment

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.

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.

Presents research results related to various aspects of palladium emissions in the environment, as well as an assessment of their effects on the environment and health. This book focuses on the following topics: analytical methods; sources of palladium emissions; occurrence, chemical behaviour and fate in the environment; and more.

Per- and polyfluorinated alkyl substances (PFAS), often referred to as per- (and poly) fluorinated compounds (PFCs), have been used for years in many everyday3⁄4 and some lifesaving3⁄4 products. However, their use has been linked to adverse health effects in humans, a problem compounded by their persistence in the environment. This book discusses the various challenges of PFAS in our environment today, including their historical use as well as their chemical and toxicological properties. It also presents robust discussion of analytical challenges and special considerations in sampling. The work goes on to give practical recommendations for dealing with these compounds in today's dynamic regulatory landscape and includes several chapters on various remediation techniques. Key Features: Comprehensive overview of per- and polyfluorinated alkyl substances (PFAS) historical use and chemical/physical properties which help us understand their persistence, transport, and transformation pathways in the environment In-depth analysis of PFAS toxicology Detailed descriptions of conventional and state-of-the-art remediation technologies Practical recommendations for dealing with PFAS in a dynamic regulatory landscape Robust discussion of important sampling and analytical considerations Perfluoroalkyl Substances in the Environment: Theory, Practice, and Innovation explores the challenges across the topical areas of regulation and management, toxicology, environmental remediation, and analytical sampling and analysis.Readers will find this text helpful in understanding complexities associated with PFAS and informing management strategies to effectively protect this and future generations.
