||Differentiating non-asbestiform amphibole and amphibole asbestos by size characteristics

||Coarsely crystalline amphibole minerals are more common than asbestos in many geological environments. Mining or construction work can result in the release of single crystals or cleavage fragments resembling asbestos fibres or fibre bundles but that are not currently regulated as asbestos. Samples of six coarsely-crystalline amphiboles and their asbestos analogs were processed to maximize the number of particles meeting the criterion for counting and also within the respirable width range. The length distributions of the particles produced showed substantial overlap between cleavage fragments and asbestos fibres. Based on these findings, recommendations are made concerning improvements in the counting and classification of asbestiform fibres.
