| Resumen |
The errors associated with measurements of exposure to respirable quartz in a 1972-1975 Finnish foundry survey are evaluated and discussed. Considerations on the precision of the flow rate in the samplers, of weighing, of quartz analysis and of total dust sampling and analysis, on the temporal variation of dust concentration, and on the interpretation of air sampling data in terms of exposure. The logarithmic standard deviations of dust concentrations at fixed sites and jobs are calculated. The term "exposure dose" is introduced and defined as the amount of contamination inhaled over a given period of time. |
