Although plastic particles in the air are increasingly coming into focus, knowledge about their distribution and effects is still limited. Chemical analyses from Leipzig now provide details from Germany for the first time: Around 4% of the particulate matter consists of plastic. Around two-thirds of this comes from tire abrasion.
It’s more so that there were already studies about this, I think. I had also heard about this years ago.
I think it’s the kind of thing people don’t retain because they don’t like it. Cars and the “freedom” they give are still very romanticized.
