Have you ever washed your car at home or the car wash and when you clean your rims they have a bunch of dust stuff on them? It's not usually black but reddish. That's break dust from the break pads. Break pads wear on the rotors.
Car mechanics would be at highest risk of exposure, followed by animals that live along windy mountain roads.
Of course they are talking about a reaction in the atmosphere that changes the particles so I wonder how it affects birds.

Secondary being ones that have chemical reactions in the air that changed them to a toxin after being emitted from the source. I was going to mention this finding but didn't have an opening during lecture.
Dave, It's also typical for humans to patch problems with band aids rather than going after the root problem.
