At EPA’s D4 meeting today: - Most reviewers industry affiliated - Most EPA scientists in sync with industry - EU, UK, Canada: “D4 very persistent and very bioaccumulatative” - EPA: “maybe persistent but not bioaccumulative” This is what corporate capture looks like www.youtube.com/live/eTZ9rjV...

a month on, @magnuslovold.bsky.social comments on the final day of UN global plastic treaty negotiations in Geneva there were rumours circulating in whatsapp groups about UNEP engaging in what might best be termed 'discretionary governance' - this blog details some of the chaos that unfolded

For the first time since Stockholm Univ. was awarded UN observer status, a researcher (Prado Domercq) attended negotiations on a global treaty to end plastic pollution as part of the Scientists' Coalition for an Effective Plastics Treaty. @marleneagerstrand.bsky.social www.su.se/department-o...

See Prof. Nina Kirchner, director of @tarfalaresstation.bsky.social, in @svtnyheter.bsky.social earlier today on how the southern peak of #Kebenekaise continues to melt. 1,5 meters since last year... 🌡️⛰️🥵 (In Swedish)

Tarfala's 80 Year Anniversary Conference @stockholm-uni.bsky.social @bolincentre.bsky.social has just started! Thank your our international speakers from Switzerland, Norway, Germany and UK making the first sessions really exciting! Artwork in the conference logo by @dominoajones.bsky.social

Scientists from Stockholm University + Swedish Museum of Natural history, in collaboration with partners in Greenland and Canada, have identified a previously undocumented class of #PFAS in blubber of killer whales. New study in Environmental Science & Technology Letters. www.su.se/english/news...

July was warm. Here are #warmingstripes @edhawkins.org showing average july temperature at #TarfalaResearchStation @stockholmuni.bsky.social @bolincentre.bsky.social. One definition of the Arctic is that July temps stay below 10 C - according to this, we are not in the Arctic...But we are...

High concentrations of nanoplastic particles were found in locations across the North Atlantic Ocean, particularly in the top 10 metres of water and near coastlines, according to an analysis in Nature. go.nature.com/44ohIok 🌊 🧪

Today we made history. Countries have come together & agreed the new Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution that will provide the 🌍 with robust, independent science. Environmental multilateralism delivering again, #ForPeopleForPlanet. www.unep.org/news-and-sto...

In a new paper, 22 scientists—including Professor Ian Cousins and Associate Professor Marlene Ågerstrand at Department of Environmental Science @stockholm-uni.bsky.social —defend the current definition of PFASs established by the OECD. #PFAS #Chemistry www.su.se/department-o...

Complaints about "viewpoint diversity" were always affirmative action for conservatives

The MAHA report highlights the need to "understand and reduce the cumulative chemical load on our children" and calls for "new risk evaluation tools" that incorporate AI... explain to me why, then, our grant from the EPA to do pretty much EXACTLY THAT was terminated 2 months after it was awarded.

New review concludes: "Nonetheless, emerging evidence indicates microplastics interact, traverse and compromise the integrity of these complex barriers." doi.org/10.1016/j.en...

🦄 Clever new accounting tricks like this intransparent mass balance scheme will not solve the #plastic crisis but rather enable increasing plastic production via #greenwashing 🔽

Last year alone, the world generated around 400 million tonnes of plastic waste. Ahead of #WorldEnvironmentDay, here’s a closer look at what plastic pollution is, why it’s such a problem, and what can be done about it. www.unep.org/news-and-sto...

I’m going to start using “eatings” to mean “food”.

I tell my students that the best things they can do for climate are to stop eating cow and dairy, stop buying so much stuff, and vote for politicians who will do something about climate change.

Cherry blossoms near Södra Huset on the Stockholm University campus April 16 2025. @stockholm-uni.bsky.social

#Massbalance calculations @vaw-glaciology.bsky.social @matthias-huss.bsky.social done - #Storglaciären @stockholm-uni.bsky.social @bolincentre.bsky.social had the largest winter accumulation (2.11 m w.e.) since 1992 and the fifth highest on record. More results to come soon :) Happy Easter!

Another view of the cherry blossoms. This time with my DSLR...

The cherry blossoms are out at Stockholm University. Not the peak yet. Maybe this weekend... @stockholm-uni.bsky.social

A leaked document reveals a PR campaign fuelled attacks on the 2019 EAT-Lancet report, which called for cutting red meat by 50% for health and climate. Scientists faced intense backlash. “I’ve never been attacked in so many ways,” said our Director Line Gordon. www.theguardian.com/environment/...

A tricky thing about modern society is that no one has any idea when they don’t die. Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

The @nationalacademies.org panel on microplastics in the environment & human exposure pathways from March 20 is online! It features me, Bart Koelmans, @traceywoodruff.bsky.social, Jane Muncke of @fpffoundation.bsky.social & @margaretspring.bsky.social. Full vid: www.youtube.com/watch?v=96rI...

New study shows (again) that none of the tested bags made of supposedly compostable #plastics (polybutylene adipate-co-terephthalate, polylactic acid, corn starch) met the ISO biodegradation criterion necessary to be considered 100% compostable. #bioplastics journals.plos.org/plosone/arti...

You think you have free will and make independent choices but then both of you on the news are white middle-aged male economists called Erik wearing glasses, grey suits, and blue ties: www.svtplay.se/video/e4dJz9... Perfectly exchangeable.

This is how it also can be :) Means we are station-bound for the coming days due to poor visibility and high avalanche risk, and can do regular office work @stockholm-uni.bsky.social @bolincentre.bsky.social

March 20th at Noon EST (17:00 CET) I will join a @nationalacademies.org panel on microplastics in the environment & human exposure pathways, with Bart Koelmans, @traceywoodruff.bsky.social and Jane Muncke of @fpffoundation.bsky.social. Register here: www.nationalacademies.org/event/44668_...

I fear a great many journalists and even environmental orgs did not read the most recent IPCC report past the Summary for Policymakers. Here's why that is a big problem: that part of the report is the only one that is lobbied to hell and back by politicians. Saudi + US pushed CCS hype into it

TarfalaResearchStation @stockholm-uni.bsky.social @bolincentre.bsky.social is now open for the season! A first check on Storglaciären revealed more winter accumulation on the #glacier so far than expected! And #northernlights are still frequent :) We are looking forward to welcoming our visitors!

The idea that the countries of the Global South will be capable of recycling materials that rich countries dump on them is unrealistic.

Visiting a lab in Lund, Sweden 🇸🇪 . Colegues here produce #nanoplastics and get their size distribution by shooting laser and seeing the Brownian motion. #microplastics

This is actually the worst thing I’ve seen from federal granting agencies thus far.

Timothy Malloy from UCLA just enlightened me about how to talk about the precautionaly principle to Americans. Just attribute the idea to Benjamin Franklin, who said in 1735: "An ounce of prevention is worth a pound of cure".

📢 Calling all #plastics scientists. #ecologists, #HumanHealth experts and #foodies! We are hosting our hybrid workshop on Plastic pollution on the 6th of March 2025. If you are interested to attend the workshop, kindly rsvp using the link: forms.gle/6tisLDBjvC9c...

Hm. People who wear contact lenses (especially females under 40) have higher body burdens of PFOA, PFHxs, and PFOS (but PFOS is not always significantly higher at 95% CI)... www.sciencedirect.com/science/arti...

Scientists don't have time to ask themselves hard questions! The brain #microplastic paper is a joke: Fat makes false positive PE - see missing high m/z ions in PyGCMS. The brain has ~60% fat, and the liver has ~5%, so that is why there are ~10x more "plastics" in the brain. doi.org/10.1038/s415...
