“…For example, Pinus wood generally has a low but variable protein content (Kespohl et al, 2010;Skovsted et al, 2003). Additionally, the dust from Quercus and Fagus is considered quite toxic and classified as carcinogenic to humans (Group A1) (ACGIH, 2014;Kauppinen et al, 2006;Čavlović et al, 2022).…”

In the present study, occupational exposure to softwood (Pinus brutia) and hardwood (Fagus sylvatica and Quercus petraea) wood dust was determined during forestry work in a timber yard. In the determination of inhalable wood dust, three operating parameters of the chainsaw were taken into account. The first operating parameter was the chainsaw operating under normal conditions, which means proper maintenance and infrequent throttle pressing. Measurements under normal conditions were referred to as reference measurements and were used for comparison. The experiment continued with measurements of wood dust concentration under two other chainsaw operating parameters, namely, improper chainsaw maintenance and infrequent throttle pressing. The determination of inhalable wood dust concentrations from the ambient air was performed using the Inhalable Organic Matter (IOM) sampler, manufactured by SKC Button Sampler (Dorset, United Kingdom). Out of a total of 108 concentration values of inhalable wood dust, 44 (40.74%) showed concentrations greater than 3.00 mg·m− 3, while in 10 (9.26%) values, the dust concentration exceeded 5 mg·m− 3. The eight-hour time-weighted average exposure to wood dust ranged from 0.99 mg·m− 3 to 12.52 mg·m− 3, with an average of 4.22 mg·m− 3. The results indicated that the increase in wood dust concentration is dependent on improper chainsaw maintenance, while infrequent throttle pressing reduces dust concentration levels. Additionally, an increase in wood dust concentration was observed in species with thick bark (Pinus brutia and Quercus petraea).

“…The share of respirable mass concentration in inhalable dust mass concentration (cr / cinh) or in total dust (cr / ctot) depends on numerous factors of particle formation and, as a rule, the share cr / cinh and cr / ctot increases with decreasing dustiness (Sass-Kortsak et al 1986;Muranko et al 2001;Kos et al 2004;Noto et al 2016;Čavlović et al 2022). In accordance with the attempt to harmonize the results of mass dust concentration measurements obtained with different filter holders, the conversion factors of total dust concentration to inhalable fraction concentration were determined depending on the sampler used.…”

Thermal modification of wood changes its mechanical properties, generally reducing its strength, such that it is more easily chipped during processing than untreated hardwood. This study presents specific parameters used in the determination of mass concentration of thermally modified (TM) hardwood by gravimetric and photometric methods. An optical device, the Split 2, was used in the active mode, of which the holder of the inhalable dust IOM (Institute of Occupational Medicine) filter was the input part. Side-by-side determination of the respirable and inhalable mass concentration was made using the Higgins-Dewell respirable dust cyclone and an inhalable dust IOM sampler. Side-by-side determination of inhalable and total dust mass concentration was made using an IOM and open-faced (OF) filter holder to establish an IOM / OF sampling ratio. A correction factor of 1.16 was calculated for applying the photometric method as the ratio of mass concentration determined by gravimetric and photometric methods. Minimal concentrations of respirable and inhalable wood dust (geometric mean: cr = 0.058 mg/m3; cinh = 0.882 mg/m3) and a 12.76% share of respirable dust in the inhalable concentration cr / cinh, had a significant influence on the efficiency of the photometric method. The mass concentration obtained by IOM and OF samplers did not significantly differ (p = 0.36).
