Ah, yes. This is a real issue.

Breathing in non-toxic particles can be bad for you due to the effects of mechanical injury. The classic example is asbestos, completely non-toxic, but the result of how your body attempts to repair damaged cells in your lungs can cause an increased chance of cancer.

This is one of the top concerns of nanotechnology. It could potentially create a lot of grit that we really don't want to breathe...

You remind me that I heard brake pad particulate was horrible for our health, and highly present in the air in LA as well - another thing to lose sleep to!

Thanks for the chat, have a nice one
