Sažetak
The aim of the research presented in this paper was to evaluate benefits and disadvantages of gravimetric and photometric methods for determination of dust mass concentration. The samples of oak-wood dust were collected in sawmill. The samples for gravimetric determination of respirable and total wood dust mass concentration were collected by stationary (N=24) and personal sampling method (N=26). The samples for photometric determination of inhalable wood dust mass concentration were collected only by the stationary method (N=38). Mass concentrations of respirable and total wood dust determined by gravimetrical method were significant different for stationary and personal sampling methods (presp = 0.0004 ; ptot = 0.0034). The results obtained by photometric method are applicable only when using the previously determined correction factor (kf = 3.34). Only the results of 8-hour measurements of mass concentration by gravimetric methods can be compared with limit values of aerosol mass concentration. However, the determination of mass concentration of wood dust by photometric method may be applied not only for short-term exposure measurements but also for additional measurements within the analysis of exposure time profile at workplaces during the working day.
