Chronic silicosis is the most common occurring after 10 20 years of low to moderate exposure of respirable crystalline silica.

"The bad part is, it's very small, and that makes it very respirable ."
13.
Some are small enough to be worn clipped to clothing, and are used to separate respirable particles for later analysis.
14.
From such samples the amount of inhalable or respirable dust can be determined and compared to the relevant occupational exposure limits.
15.
Using a jackhammer to break up concrete pavement may expose the operator to hazardous dust containing respirable crystalline silica ( RCS ).
16.
Even if that respirable airborne particulate matter does not include a single chemical, it is incredibly toxic at that level of exposure,
17.
The respirable dust fraction is dust that enters the'deep lung'and is considered to be less than 10 micrometers AED.
18.
The fine, respirable lunar dust could thus be toxic if the astronauts are exposed to it during mission operations at a lunar base.
19.
It is of course fiction, but my personal guess would be, that the air would be still be respirable ( although not very healthy ).
20.
Examples of these subsets of the particle-size distribution of an aerosol, important in occupational health, include the inhalable, thoracic, and respirable fractions.
