inhalable wood dust

Very fine wood dust — 100 micrometers (μm) or smaller — can be inhaled into the lungs. Once there, the particles can (TODO) and cause cancer.

Even good dust collection systems in wood shops mostly get the larger particles. Smaller particles will hang in the air (or land, but then later be kicked up when disturbed). The best way to remove these is with an air filtration system. [1]

In academic journals, three different sizes of wood dust are discussed:

"Human respiratory tract deposition modelling showed that the deposition of the particle surface area in the size range of 0.3–10 μm was mainly in the extrathoracic region, and the particle surface area in the size range of 5.6–560 nm was mainly deposited in the alveolar interstitial"
