Can dust become airborne?

Airborne dust is a by-product of most industrial processes and can constitute a threat to equipment and people. But airborne dust can be mitigated by control of relative air humidity.

Do dust particles move up?

The dust particles do travel upwards, but only up a thin “chimney” of rising air, heated strongly and rapidly by the bulb, which would be at several hundred degrees Celsius.

Does dust ever leave your lungs?

These tubes are called bronchi and bronchioles. All of these airways are lined by cells. The mucus they produce catches most of the dust particles.
