My last (but certainly not least) paper from my PhD! Our latest research article on the #fate of newly developed #PFAS in wastewater treatment plants (WWTP) and surface waters has been published in Environmental Toxicology and Chemistry! 📝Our study unveils an exciting finding: hydrofluoroether PFAS containing thioethers, used in novel surfactants, have the potential to completely break down in the environment! This highlights the importance of intelligent chemical architecture and opens new doors for environmental protection and sustainability. 🌱 I'm immensely thankful to everyone who helped out on the project, WWTP sludge wasn't the most glamorous sampling, but most chemical waste ends there at some point! Let's continue pushing boundaries for a cleaner, safer, more informed world. 💧 #EnvironmentalScience #Research #WastewaterTreatment #Sustainability #FateAssessment (Open access article below)

Relevant for Life Cycle Assessments of chemicals in products, and choosing safest options for a function, because of vast expansion on number of compounds that can be evaluated, and because of derivation in line with today's global LCA consensus method (known as UNEP-Life Cycle Initiative GLAM process). https://lnkd.in/etRuZ5nK

This Sience commentary by Robert F. Service highlights a breakthrough that could signal a turning point for PFAS remediation. PFAS, the forever chemicals, are significant contributor to our exposome. The two independent studies published in Nature show how light-powered catalysts can break down PFAS under mild conditions, offering a cost-effective and environmentally friendly solution compared to current high-energy approaches: Study 1: Researchers at the University of Science and Technology of China developed a violet-light catalyst to dismantle PFAS. Released fluorine atoms are captured as non-toxic potassium fluoride. Study 2: Colorado State University researchers created a blue-light catalyst that replaces fluorine atoms with hydrogen, transforming PFAS into useful hydrocarbons. As noted in this commentary, these studies "show these carbon-fluorine bonds are not as inert as we thought." While challenges like cost and scalability remain, these discoveries signal progress in the fight to mitigate PFAS contamination sustainably. Such science-driven solutions are crucial towards a better environment and a better health. #PFAS #EnvironmentalHealth #Exposome #SustainableSolutions #ScienceLeadership #YSPH #Yale #NIHES #GreenChemistry #PublicHealth

PFAS or forever chemicals are getting a lot of attention lately, including by the Minnesota legislature, which just passed a law that bans nonessential use of PFAS and makes it illegal to sell or distribute some products with intentionally added PFAS. Researchers at the University of Minnesota are also thinking about PFAS. Included among these researchers is Matt Simcik, whose research focuses on how and why organic pollutants end up in the atmosphere and water, and Christy Haynes, who has designed nanomaterials from different earth-abundant elements that can interact with PFAS and facilitate PFAS uptake into plants, which removes them from the soil.

Great piece from Sally Brown at BioCycle. The debate around the safety of biosolids is utterly toxic (pun intended). Time and again it has proven safe for use within the bounds of available evidence and risk assessment capabilities. However... it is undoubtedly the final output from an open pipe process, with few deliberate controls over the quality of inputs from which it's derived - meaning that it's characteristics will reflect those of the activities which take place in the associated sewer catchments. We need a dispassionate debate around the nature and quality of available data on biosolids, our ability to build robust risk assessment models on those data - and the implications of switching to alternate solutions. We also need to get much better about communicating risk. https://lnkd.in/eTrpT8M2

⚠️ Beware: Trifluoroacetate – A Harmful Forever Chemical 🧪 Did you know trifluoroacetate (TFA) is a game-changer in chemical reactions? This strong acid plays a key role in organic synthesis, catalyzing reactions and purifying compounds in the pharmaceutical world! Whether you're into biochemistry, drug development, or just fascinated by cool chemical structures, TFA is a versatile player that never gets old. While trifluoroacetate (TFA) plays a vital role in industrial and pharmaceutical processes, it’s also classified as a forever chemical, persisting in the environment for centuries. These compounds don’t easily break down, accumulating in water, soil, and even wildlife. Long-term exposure can pose risks to ecosystems and human health. Let’s stay informed and work towards sustainable solutions! 🌍♻️ #ForeverChemicals #EnvironmentalAwareness #PollutionPrevention #EcoHealth #SustainableScience #GreenChemistry #SaveOurPlanet #ChemicalFootprint https://lnkd.in/dSYN9i62
