Commercial tea bags release millions of microplastics, entering human intestinal cells (medicalxpress.com)

UAB research has characterized in detail how polymer-based commercial tea bags release millions of nanoplastics and microplastics when infused. The study shows for the first time the capacity of these particles to be absorbed by human intestinal cells, and are thus able to reach the bloodstream and spread throughout the body.

There is also this page that says which tea brand don’t use plastics with sources to the announcement.

Unless they were talking about PLA plastics which from a (very) quick search seems to pose no risk

I have more bad news: [https://www.sciencedirect.com/science/article/pii/S0048969724007307](Are bioplastics safe? Hazardous effects of polylactic acid (PLA) nanoplastics in Drosophila)

Your study is from 1/4/24 the one I linked is from 26/6/24

Or am I just being a muppet here?

Silly me. Glad that is resolved.

Findings from a new meta-study sponsored by Holland Bioplastics, Futerro, TotalEnergies Corbion, and NatureWorks reveal that PLA ‘eventually’ fully hydrolyses and biodegrades in the environment

This is the summary blurb at the top of the article.

I would be very skeptical of ingesting something and believing it harmless if the study finds that it eventually breaks down in the environment, let alone it’s clearly funded by a company with ‘bioplastics’ in the company name.
