Recent developments in fibrous aerosol measurements.
J Environ Pathol Toxicol 1979 May/Jun; 2(5):335-343
A portable survey instrument and a laboratory instrument for counting fibers on a filter are described as alternative instrumental techniques to the light microscope counting method for evaluation of asbestos (1332214) exposure. Asbestos detection for both instruments is based on fibrous morphology. The portable fibrous aerosol monitor (FAM) was studied in the laboratory and in field situations; and it is operational, although there are problems under certain conditions. The fiber counting instrument will be able to automatically count a larger filter area in a shorter time than a human counter using present methods. The author concludes that both instruments together should provide improved efficiency and precision for evaluation of exposure to asbestos and other fibrous dusts.
