As countries negotiate a global treaty to address the plastic pollution crisis, in this new study we identify thousands of chemicals in plastics - many harmful and largely unregulated.

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!

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):

🧪💶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.

Big updates this month to the ZeroPM Regulatory watch - on updates to #PFAS and #PMT substances in the EU
Highlights:
- PFAS in the Soil Monitoring Law
- PFAS in the Water Resilience Strategy
- @echa.europa.eu launches consultation for #TFA as PMT, vPvM and Reprotox 1b

‼️ @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.

Plastic-Associated Chemicals: Late Lessons from Early Equilibrium Partitioning Science
In this viewpoint we argue why different fields looking at the hazard and risks of plastic associated chemicals can and should unit using a common, existing framework.

A group of leading European scientists have sent an open letter to the European Commission urging stronger regulatory measures against chemical mixtures in the upcoming revision of REACH—the EU’s main regulation for chemicals. @marleneagerstrand.bsky.social

Researchers say the rule will make it impossible for the majority of scientists in the country to carry on with, or to apply to, prestigious ERC research grants, or grants from Serbia’s own national science foundation.

The Tibetan Plateau region is an important source of freshwater for two billion people. Climate change has been releasing substances from the permafrost. We reviewed the literature and applied a ML model to identify #PMT substances that are a concern to water quality.

NEW!: 3 UK military bases have been marked for investigation over fears they may be leaking toxic forever chemicals into drinking water sources and important environmental sites.
In the US, billions of dollars has been spent on military site contamination.

MoD investigating military bases in Norfolk, Hampshire & Devon feared to be leaking PFAS forever chemicals - including globally banned PFOS & carcinogenic PFOA - into drinking water sources. Our article in today's @theguardian.com

This visit is related to the implementation of the new #PMT and #vPvM hazard classes introduced in the EU #CLP Regulation - with Raoul Wolf and Anne Deininger
Agreed. Two points from the article to highlight:
1. The lack of mechanistic plausibility that particles larger than 1µm can cross blood/membrane barriers (from decades of air pollution research):
2. Results of polyethylene in tissues/blood cannot be trusted due to molecular similarities to lipids
I’ve spent the last 8 years working on a book about forever chemicals, or #PFAS, and the chemical industry’s decades-long campaign to cover up their dangers. What I discovered along the way is deeply disturbing, and yet the journey has left me hopeful.

US President Donald Trump is taking a wrecking ball to science and to international institutions. The global research community must take a stand against these attacks.

#PFAS in Europe - quo vadis? ARTE did an excellent, well-produced 10 minute news clip covering the concerns of PFAS in Europe, from its effects, clean-up and the phase out. I was very happy to be interviewed as part of this to talk about effects, clean-up and phase-out.

Yeah - old school playbook that they claim free speech while banning words, ca Orwellian "1984" Newspeak. That being said, based on the previous 2016 Trump restrictions on freedom of speech, I am most surprised by "Emissions" being banned. Perhaps its because of embarrassment of nocturnal em......
