Definitions for "Dusts"
Solid particles generated by handling, crushing, grinding, rapid impact, detonation, and decrepitation of organic or inorganic materials, such as rock, ore, metal, coal, wood and grain. Dusts do not tend to flocculate, except under electrostatic forces; they do not diffuse in air but settle under the influence of gravity.
Dusts are solid particles generated and dispersed into the air by, for example, handling, crushing and grinding of organic or inorganic materials such as rock, ore, metal, coal, wood and grain.
Formed when solid materials are broken into small particles.
a pesticide formulation consisting of a pesticide active ingredient and a carrier such as talcum powder, corn cob, etc.
usually a specially prepared formulation for dry application in which the active ingredient is diluted with an inert dust to a low concentration for direct application. Wettable powder formulations should not be used as dusts. The rate of absorption of the active ingredient by the skin is usually greater for a wettable powder than for a dust preparation with equal concentrations of active ingredient.
