Mapping the chemical complexity of Plastics - now published in @nature.com! This we hope will be used as a launch pad to make plastics and materials more safer and circular!
Mⓐrtin Wⓐgner@martiwag.bsky.social · last yr.Over the past few years, our PlastChem team has worked tirelessly to map the chemical complexity of #plastics. Today, we publish the findings in @nature.com. We hope this evidence propels the development of safer plastics to protect human health and environment. 1/4 www.nature.com/articles/s41...
Breaking #TFA news: The Danish Ministry of the Environment is withdrawing the approval of 23 #pesticides because the products contain active ingredients that can form and leach #TFA into groundwater. This is the first country to ban #PFAS pesticides. Press release (Danish): mst.dk/nyheder/2025...
🧪💶Ambitious chemical regulations boosts the economy. A The European Parliamentary Research Service report warns, however, chemical policy needs a strong #REACH and #PFAS strategy to get the best cost-benefit outcome and save the most lives. Full report: www.europarl.europa.eu/thinktank/en...

‼️ @global2000.bsky.social have tested cereal products in Austria for TFA, finding all products to be highly contaminated. 😥TFA is a type of #PFAS and is currently under consideration for hazardous classifications such as toxic to reproduction. More in our #ToxicFree4EU briefing: buff.ly/0b9IKLC
In this lysimeter study we studied the impact of using biochars to reduce mobility of PFAS in soil. Over 100 years, nearly all PFOS are predicted to leach from no-sorbent lysimeters, while < 1 % will leach from soil treated with sewage sludge- derived biochar. www.sciencedirect.com/science/arti...

This kept me up last night. I don’t think most people realize how much US science has slipped in the last 10 years. I’ve already received unsolicited competitive recruitment offers from Chinese universities. Other counties see what’s happening here and know exactly what to do.
Rebecca R Helm@rebeccarhelm.bsky.social · 2y agoWe’re already seeing a slow down in international students, meaning the US is no longer seen as a world class leader in scientific research. In the last ten years China has taken the lead in a number of fields (chemistry, to name one)…
