Tiny solid airborne particles. Particulates are a type of pollution composed of Soil, Soot, proteins, and salts. They range in size from below 1 micrometer to about 10 micrometers. Particles above 10 micrometers tend to settle out quickly. Suspended particles smaller than 1 micrometer are called aerosols. They can provide a nucleus for condensation.
