New blog post. A mass balance shows that 11-13 million tonnes of plastic escape into the environment every year in the EU. This is not just a leakage—it’s systemic.

There is no solid evidence that plastic particles can cross the blood-brain barrier. The article you’re probably referring is a bad use of Py-GC/MS. Most toxicological results use high concentrations of unrealistic particles like PS latex. Probably I have read much more than you.

Recent article in Journal of Hazardous Materials: Aquatic toxicity of UV-irradiated commercial polypropylene plastic
particles and associated chemicals.

Should we be worried about the presence of micro- and nanoplastics in drinking water? Do they pose a health risk?rosal.web.uah.es/en/blog.html
