You keep saying deep into the lungs. You don't exchange that much air "deep into the lungs" unless you're really huffin and puffin. And mucus nor cillia don't care what the um is of the particle. They move out bacteria and viruses the same way.
If you were chronically dehydrated sitting behind an exhaust stack belching black smoke for years while you were breathing deeply and you had had already or were concurrently frying your goblet cells and cilia because you're also a smoker, then yes, you would be correct. However, chemical vapor don't work the same way. It 100% goes to wherever the air travels to and is absorbed into the cells to cause DNA damage.
In the event that soot particulate gets lodged in a cell, the immune system will try to gobble it up or the cell will try to push it out. If the cell survives and the two former things failed, the damage the particulate causes is what can cause the cell to act a fool.
There's a few other ways, but I'm not explaining them to you. Go get your own medical degrees.
EV is likely worse. Look up lithium mines and its battery production pollution. Look up the few economical methods of charging that junk. How do they produce that power?
Finally, what carcinogens come out of the the infallible burn cycle you're touting as the it's saving grace/what's the ash particulate size?
I'm afraid Ning is right, and you're wrong, about PM2.5 incursion into the body and bloodstream. I'm not saying chemicals don't also cause problems, but ignoring the dangerous consequences of PM2.5 on personal health is naive.
