Clickbait. "The toxicity and health effects of brake wear particles are largely unknown". Is there any real harm found? What's the concentration of them close to the dangerous road? What's effect of them comparing to pm10 or pm2.5?

[whatshisface]

The brake pad particles are pm10 and pm2.5.

[varelaz]

Well I meant other particles treated in the regular study of them. Because effect of pm10 and pm2.5 is studied. Do break pad particles somehow worse than usual.

Do you really need an independent peer-reviewed study to know if inhaling brake dust is bad for you or not?

At some point, it's important to trust your instincts. I don't think you need a medical degree to understand that inhaling tiny particles made of nasty stuff leads to bad health outcomes.

While the sentiment on that is laudable, it's that kind of assuming that leads all kinds of idiots to jump to entirely ridiculous conclusions.

[grecy]

Given that we're on HN, I was assuming that everyone here is educated and has some kind of basic reasoning skills. Common knowledge and all that.

[varelaz]

Instincts often cheat you. I'm not saying that it's healthy but Does it really have any effect at all? What's the concentration of particles? How harful is it comparing to cooking or peeling onions? Do we need to care about it at all?

Familiar with asbestos? Its pretty widely regarded as a bad time

Asbestos in brake pads is no longer an issue I'd hope.

breathing any kind of dust is usually bad for you... even wood saw dust.
