The survey found concentration of microplastic particles ranged between 0.3-25 microplastic particles per gm of moss. Proximity to urban areas did not fully explain this variation, so still more to learn! Open access paper in Microplastics and Nanoplastics: link.springer.com/article/10.1... 2/2

The first national-scale study of its kind, led by UKCEH, has found detectable microplastics in moss at 94% of UK rural sites surveyed. Lead author @richardkcross.bsky.social discusses the findings & importance of such surveys as production/use of plastics increases. 🔗 tinyurl.com/yc2acct4 🧪 1/

Forensic approaches to microplastic detection in bodies of humans and animals will boost confidence in results, says UKCEH pollution scientist @richardkcross.bsky.social. He was part of a team proposing a new approach after scrutiny of some high-profile studies. www.ceh.ac.uk/news-and-med... 1/ 🧪

🌍 A UKCEH team were observers at the latest UN talks on a global treaty to end plastic pollution. Negotiations ended without consensus after 2 intense weeks, but there are glimmers of hope 🔗 tinyurl.com/mrxmfm87 🧵🧪 1/ @samharrison.science @richardkcross.bsky.social @feuchtmayr.bsky.social #INC5

Not your typical #litter floating past in the Rhone this morning here in Geneva! Sadly not Swiss Francs I'm afraid 😂 A moments break this morning before starting on what should be the last day of the #GlobalPlasticsTreaty negatiations

#Live now! As the #PlasticsTreaty #INC5.2 negotiations nears its end, delegates and observers gather in plenary in the Assembly Hall at Palais des Nations. Follow the plenary on UN TV 📺 webtv.un.org/en/asset/k1r...

How are things at the #GlobalPlasticsTreaty #INC5.2 #PlasticsTreaty? My colleage @samharrison.science @ukceh.bsky.social nicely sums up some of the key moments over the last week 👇

I'm on my way to Geneva for #INC5.2 - the final session for nations to negotiate a #GlobalPlasticsTreaty As the negotiations near their final stage, it is now more than ever crucial that decisions are grouded in science. The @ukceh.bsky.social delegation is going with five key messages 👇

To find out more about what @ukceh.bsky.social are up to at #INC5 #GlobalPlasticsTreaty see our latest blog below👇 I'm particularly interested in how existing #plasticpollution is considered and what happens next around implementation and effectiveness #microplastics www.ceh.ac.uk/news-and-med...
