Inhalation |
||||||
|
Inhalation involves those airborne contaminants that can be inhaled directly
into the lungs and can be physically classified as gases, vapors, and
particulate
matter that includes dusts, fumes, smokes, and mists. Inhalation, as a route of entry, is particularly important because of the rapidity with which a toxic material can be absorbed in the lungs, pass into the bloodstream, and reach the brain. Inhalation is the major route of entry for many hazardous chemicals in the work environment. |
