par·tic·u·late

(pər-tĭk′yə-lĭt)
Adjective
Formed of very small, separate particles. Dust and soot are forms of particulate matter.
Noun
A very small particle, as of dust or soot. Particulates that are given off by the burning of oil, gasoline, and other fuels can remain suspended in the atmosphere for long periods, where they are a major component of air pollution and smog.
