Have "unsafe levels" been established, or are we just assuming that any is bad?

Edit: I see they appear to be using the European Food Safety Authority (EFSA) intake limits for most of their tests.

Initial data says they're at least bad for sea life. Doubtful it's good to have such durable micro materials bouncing around our lungs and digestive tracts. Stopping pollution is also much easier than cleaning up after the fact.

Having odd things in your lungs is bad. Having things bouncing around in your digestive tract means nothing. The whole point of the digestive tract is that you put untrusted materials into it.

As long as it actually makes it out the other end. Bits of undigestable matter the size of smoke particles is a relatively new phenomenon.

Uh, smoke particles and mineral dusts are generally non digestible - and we’ve been eating smoked/cooked meats and slightly dirty things for at least as long as recorded history?

[thatcat]

isnt smoked/charred food associated with colon cancer?

[MVissers]

Yes.

And the last decades we’ve had a new unknown cause of colon cancer increase in young adults.

My money is on plastics, but will be hard to prove.

[lazide]

Many of the chemicals in smoke particles cause cancer with extended contact.

But not new. At all.
