Asbestos dust exposure is a documented hazard, a classic example of a cause of illness originating in the industrial and mining environment. A vital aspect in the prevention of asbestos exposure is measurement of the concentration of air borne asbestos. Currently, the most widely accepted method of measuring air concentrations of asbestos is to collect a sample of air borne dust on a filter and then analyze the filter by phase contrast light microscopy. The current NIOSH recommended version of this technique is described in physical and chemical analysis method 239 (PCAM 239).
