Because of their tiny size, they can get deep into the lungs and, once in the bloodstream, may be able to cross the blood-brain barrier and enter the brain by translocation along the olfactory nerve.
Abstract
Because of their tiny size, they can get deep into the lungs and, once in the bloodstream, may be able to cross the blood-brain barrier. Particles deposited in the nasal region may be able to enter the brain by translocation along the olfactory nerve. Particles, especially composites, may be able to penetrate the skin, and even some protective equipment. The smaller the particle, the more likely it is to be suspended in air, and hence, be available for inhalation/ingestions.
