PFAS (per and polyfluoroalkylsubstances) are known to be extremely difficult to degrade in the environment and to be bioaccumulative and toxic. Exposure to PFAS is suspected to increase the risk of adverse health effects, such as impacts on the thyroid gland, the liver, fat metabolism and the immune system. This study estimates the socioeconomic costs that may result from impacts on human health and the environment from the use of PFAS. Better awareness of the costs and problems associated with PFAS exposure will assist decision-makers and the general public to make more efficient and timely risk management decisions. Findings indicate that the costs are substantial, with annual health-relat...

A discussion of the synthesis, problems, theories and applications of fluorinated surfactants, this second edition is updated with four new chapters on repellency and protection against soiling and staining and over 2900 references, equations, and drawings (800 more than the previous edition). It lists alphabetically and explores numerous applications of fluorinated surfactants. Called "...a most useful introduction to these fascinating materials" by the Journal of Dispersion Science and Technology and "...a coherent and stimulating handbook...the most useful book in the fluorinated surfactants field to date. Recommended." by the Journal of the Chemical Society, Faraday Transactions - this book is a source of factual data, methods of manufacture, and chemical structures for the surfactant scientist and user.
Das Personenregister der DBE verzeichnet in alphabetischer Reihenfolge alle Namen von historisch fassbaren Personen, die in den Bänden 1 bis 10 einen eigenen Artikel haben oder im Text genannt sind. Beim Registerstichwort werden neben dem vollen Namen der Beruf sowie Geburts- und Sterbejahr genannt. Namensvarianten, Geburtsnamen, Pseudonyme etc. werden durch ein Verweissystem aufgeschlüsselt; verwiesen wird auf den Namen, unter dem der Artikel in der DBE zu finden ist.
Through a combination of resource efficiency, climate mitigation, carbon removal, and biodiversity protection policies, this report finds that it is feasible and possible to grow economies, increase well-being and remain within planetary boundaries. The analysis and modelling presented in this report are a first attempt to understand the impacts of our growing resource use, and to develop coherent scenario projections for resource efficiency and sustainable production and consumption that decouple economic growth from environmental degradation.
Describes the current status and potential of synthetic chemistry designed to use and to generate fewer hazardous substances. Examines new techniques for carrying out transformations in environmentally benign solvent systems. Presents research results on the replacement of hazardous feedstocks with biologically derived, innocuous feedstocks; of hazardous reagents with visible light; and of phosgene, benzene, and halogens in a variety of industrially important reactions. Provides examples of how alternative synthetic design for pollution prevention has been made commercially viable. Describes how to conduct a source-reduction assessment and analyzes computer-assisted synthetic design.
