Abstract
Provided is a method for detecting respirable participles in a bulk material comprising particles. The method comprises: analyzing morphology of the particles; analyzing chemical composition of the particles; creating a profile of the particles, wherein each particle in the profile is characterized by its shape, size and chemical composition; selecting particles from the profile which match the size and chemical composition of a respirable particle; and calculating a percentage of the respirable particles in the bulk material.
