Applicability of photometric method for determination of wood dust mass concentration in woodworking environment
The aim of research presented in this paper was to evaluate reliability and applicability of photometric methods in determining mass concentration of wood dust in the woodworking environment in comparison to gravimetric method. The samples of inhalable wood dust was collected in several plants of mechanical processing during machining of wet oak-wood (N=18), dry oak-wood (N=15), wet beech-wood (N=14), dry beech-wood (N=23) wet fir-wood (N=10) and particleboard (N=10). Relationship between the results obtained by the photometric method and values obtained by the gravimetric method is significant (Spearman's rho=0.8, 88 d.f., P=0.000) and this is the base for using the photometric method in determining mass concentration of airborne wood dust. The obtained correction factors of photometric method has high dispersion among and within sample groups. The mean values of correction factors for different groups of samples are significantly different. Such results present the usage complexity of photometric method for determination of wood dust mass concentration.
