The human lung and treachea are designed to remove dust with constant reverse action by the cilia.....Asbestos is unique will hook into tissues and not come out easily and has been a historical problem....long time hard work without smoking has been proven to remove most dust types......autopsies prove that...even inthe middle east that is full of dust storms and sandstorms...no smoke = generally clear lungs.
Black lung disease in coal miners and other forms of chronic obstructive disease from dust in the lungs is almost 100% from a secondary foreign matter that clogs and kills the cilia, not from the coal dust or wood dust but from the tar buildup from smoking and it is the tar buildup that captures the dust, whatever kind it is.....the big problem is smoking and sticky tar buildup..I have seen a lot of lungs clogged with tar from smoking and that tar is loaded with pollen, dust, crap and other **** that is trapped in the la brea tar pits the lungs turn into and is a likely source of the lung cancer... people who don't get the dust but smoke, generally just get emphysema...
The most tragic is the guy who has emphysema and gets his lungs cut in half to restore function and then starts smoking again.....so dust collection is good for everyone, but best for smokers for sure.........
