Toxic plastic pollution is everywhere, even clogged arteries. We asked a Colorado doctor how to stay healthy. (www.cbsnews.com)

Micro- and nano-scopic sized pieces of plastic people use everyday can eventually find its way into the most unlikely of places, even in the plaque of clogged arteries of cardiac patients, a recent study found.

"If microplastics might be promoting coronary disease, you might not be able to avoid ingesting the microplastics, because they're everywhere, but you can sure do the other things. You can keep your blood pressure low. You can exercise. You can get your cholesterol measured," Gerber said.

Right, but PFAS isn't even plastic, it's a chemical used as a coating to make things like take-out containers waterproof. PFAS is its own environmental catastrophe, but it doesn't relate to whether microplastics are toxic.

Plastic itself isn't toxic, in fact plastic is biochemically inert (not a source, but further reading on Wikipedia). Various additives to plastic have been shown to be toxic, but those are less relevant to discussions of accumulating microplastics in the body.

Some contexts would be more likely to have negative health impact from microplastics, like when there are larger particles of plastic in the air that factory workers get in their lungs, maybe those particles could cause mechanical damage to the lungs that lead to cancers or other conditions.

That is speculative, and it shows we need more studies to find ways that microplastics impact health, but the title is a little misleading characterizing plastics as toxic in the context of microplastics in arterial plaque, since that is not demonstrated to pose a health risk (even if we all agree it is concerning and may pose some kind of health risk we aren't yet aware of).
