Dust was a term for an accumulation of particles of various origins.

By April 2151, the only other inhabited planet besides Earth Trip Tucker had visited, featured only dust-dwelling ticks. Later, Malcolm Reed claimed if he didn't realign the navigational deflector of Enterprise NX-01 space dust would damage the hull of the Enterprise. (ENT: "Broken Bow")

In 2266, Eve McHuron apologized for coughing, saying it must be the dust in the air that caused it. Ben Childress told her Rigel XII was always like that. (TOS: "Mudd's Women")

In 2267, Montgomery Scott attributed the shorting of a circuit on the SS Botany Bay to dust. (TOS: "Space Seed")

In 2268, Spock noted the presence of dust on various instruments in the Vians' laboratory, suggesting they had not been used for some time. (TOS: "The Empath")

The nebula encountered by the USS Voyager in 2371 consisted of hydrogen, helium, hydroxyl radicals, and some local dust nodules. That was no problem for Voyager to navigate. (VOY: "The Cloud")
