One of the key research fronts to remove #PFAS from water cheaper and more effectively is to develop Anion Exchange Resins #AERs that can selectively or preferentially sorb #PFAS anions over other anions. In this new #ZeroPM study, Lukas Lesmeister conducted a series of batch experiments to enhance our understanding of PFAS adsorption onto #AERs by elucidating correlations of adsorption with influential factors such as the functional resin groups, PFAA chain length and functional group, and the competitive effects of sulphate and chloride.

💙 You are invited to ZeroPM #Webinar: "A Global Perspective on the Persistence and Mobility of Regulated Chemicals" with Sivani B. and Raoul W. from the NGI - Norwegian Geotechnical Institute When: 4th of December 2024, 15.00 – 16.00 CET More info and registration link: https://lnkd.in/dThn-nzh

Parallel keynotes by ZeroPM researchers were held at two different conferences last week, with one conference on #SSbD and the other on #EnvironmentalMicrobiology Emma Schymanski presented a keynote at the Safe and Sustainable by Design (#SSbD24) Conference at Monte Verita, Ascona, with the presentation "The Importance of Open and FAIR Data for SSbD". The slides can be found here: https://lnkd.in/dP2dhHZV More info about #SSbD24 here: https://lnkd.in/d5pYrNn5 At the same day, Hans Peter Arp presented a keynote at the 4th International Conference in Microbial Ecotoxicology #EcotoxicoMic24 "A persistent problem: identifying and confronting persistent, mobile and toxic (PMT) substances", focusing on how the Environmental Microbiology community could address the "P" and "T" in PMT substances for prevention, prioritization and removal.

At long last!! What a gratifying and relieving feeling it is to see the outcome of my almost every day work life over the last two years being published. The #CLP Guidance (part 4.3) has now been updated to include, among many others, assessment elements for #persistent, #bioaccumulative, #mobile and #toxic substances. https://lnkd.in/dt6R-uWx Many thanks to all contributors (Member States, #European Commission, Stakeholder experts), as well as the brilliant internal #ECHA drafting team of Kostas Andreou, Anu Kapanen, Jane Caley, Doris Hirmann, Aiga Latsone, Romanas Cesnaitis, Simon Uphill. It has been a heavy responsibility and great privilege to co-ordinate this multi-disciplined project from the very start. Let us all make good use of the updated CLP Guidance, for the protection of human health and the environment 

🔖 📚ZeroPM regulatory watch update for November 2024 Headlines on #REACH, #PFAS and #CLP: - Commissioner for the Environment Jessika Rosswell commits to publish the legislative proposal for the #REACH revision in 2025. - Further regarding #PFAS Commissioner-designate Roswall indicated that she would ‘seek a ban the use of PFAS in consumer uses, such as cosmetics, food contact materials and outdoor clothing’ and ‘would support the continued use of PFAS in industrial applications, in particular critical ones, under strictly controlled conditions’ where ‘adequate alternatives in terms of performance and safety are not available’. - Member States call for swift REACH revision and PFAS restriction - Revised CLP Regulation and revised Urban Wastewater Treatment Directive adopted by Council - European Chemicals Agency hosts webinar on new #CLP hazard classes and guidance all this and more at https://lnkd.in/eiG5Wse3

🌎 A new study makes the case that trifluoroacetic acid (TFA), an atmospheric byproduct of #HFO1234yf and other f-gases, meets the criteria of a “planetary boundary threat” because of increasing planetary-scale exposure, where “potential irreversible disruptive impacts on vital earth system processes could occur.” 📘 The study, “The Global Threat from the Irreversible Accumulation of Trifluoroacetic Acid (TFA),” was published October 30 in the journal Environmental Science & Technology. Its authors are Hans Peter Arp. and Andrea Gredelj of the NGI - Norwegian Geotechnical Institute; Juliane Glüge and Martin Scheringer of the Institute of Biogeochemistry and Pollutant Dynamics, ETH Zürich; and Ian Cousins of the Department of Environmental Science, Stockholm University. The study received funding from ZeroPM and ARAGORN EU. 👉 Read more: https://lnkd.in/dFmr95NX #GoNatRefs #NaturalRefrigerants #TFA #PFAS #Fgases Michael Garry Sign up to our NaturalRefrigerants.com weekly newsletter https://lnkd.in/dBj2FWvR

#TFA is a tricky #PFAS, where it is a accumulating in the environment with no possibility of natural or cheap #removal from wastewater/drinking water. In this article, ZeroPM researchers say that #TFA and its precursors shouls be #prioritized for #prevention.

🧩#ZeroPMPieces #26 Sivani B., a Post-doctoral Researcher at NGI - Norwegian Geotechnical Institute, presents how data science approaches can be used to assess mobility via the Koc values for the Global Chemical Inventory, as part of #PMT and #vPvM Assessment. With the lack of reliability in experimental values in REACH registered databases, and a distinct lack of meta data, Sivani presents how we are currently applying this approach to predict and assess the probability of each of the 340,000 chemicals in the global chemical inventory as being mobile, very mobile, or not mobile. Consensus based physical-chemical property data is preferable to using a single estimated or experimental value where reliable and applicable models are available.

There has been a lot of buzz around the keynote of Ian Cousins at the recent #REMTEC meeting in #Colorado on ways to identify #Alternatives and #Substitutes to #PFAS. Curious to learn what the buzz is about? We now have the slides available for all to view on Zenodo! Have a look where you can some the great work going on in ZeroPM on developing approaches to transition away from #PFAS here: https://lnkd.in/dcqrynnw Many thanks to Mohamed Ateia Ibrahim for the great pic below!

🧩#ZeroPMPieces #24 Maxim Carlier, a Doctoral Researcher at Vrije Universiteit Amsterdam, presents how he embarked on creating in vitro hazard profiles for persistent, mobile substances, including 16 #triazoles, 9 #triazines, and 11 poly- and perfluoroalkyl substances (#PFAS) based on their agonistic and antagonistic effects in estrogen receptor (ER), androgen receptor (AR), and thyroid hormone receptor (TR) reporter gene assays, their ability to bind human transthyretin (TTR), and their effects on steroidogenesis! These results can also be found in a recent peer-reviewed paper! Such bioassays are an important step prioritize persistent and mobile substance for further research, emission reduction, environmental remediation, and regulatory purposes.
