Beryllium sampling methods.
NIOSH 1976 Jul; :1-26
A comparison was made of three methods used to determine airborne beryllium (7440417) concentrations. A NIOSH contractor sampled its beryllium production facility by the Atomic Energy Commission (AEC), personal total, and personal respirable sampling methods over a period of 1 year. All samples were analyzed by atomic absorption spectroscopy. No reliable conversion was observed to exist between results obtained from the three methods on a single sample basis. However, it did appear that for large numbers of samples taken under the same sampling conditions, when the concentration was 2 micrograms per cubic meter (microg/m3) beryllium, as determined by the AEC sampling method, then the value as determined by the personal respirable sampling method was approximately 1microg/m3 beryllium and the value as determined by the personal total sampling method was approximately 3microg/m3 beryllium. The authors caution, however, that the large variability involved in these data could make prediction based on single samples or a small number of samples highly misleading.
