“…In that case, the sampling of wood dust was collected inside the test chamber. Another way to characterize dust emissions was to place the particle instruments next to the production site at a distance of about 1.5 m. It was chosen to represent the exposure situation of the machine operator (Gu et al 2018). In both cases, the collection and characterization of wood dust in such an opened area is difficult.…”

“…The mechanical transformation of wood material generates particles of wood of different sizes, from millimetres through microns to nanometres. According to Gu et al (2018), exposure to wood dust can cause recognised occupational diseases, such as irritation of the skin and mucous membranes, various allergies, respiratory diseases, and cancers. As such, wood dust was classified as a Group I carcinogens by the International Agency for Research on Cancer (IARC) in 1995 (Blackadar 2016;IARC 1995;Micallef et al 2018;Ojima 2016) and continues to be a subject of occupational health concerns worldwide (Matrat et al 2019;Stellman et al 1998).…”

Particles generated by wood machining have a proven impact on the health of users and woodworkers. The aim of this study was to quantify and describe wood particles in solid and gas phases to reliably and reproducibly characterise these emissions. First, we developed an experimental device that produced particles from solid wood and wood-based panels using portable machine tools. The objective was to study the particles emitted by wood machining while avoiding ambient pollution. Based on own technical specifications, the experimental system was defined and composed of various elements that integrated treatment of inlet air through wood machining to the analysis section that allows solid and gas phases. The first experiments were carried out in sanding and sawing modes on materials used in construction, including solid wood (spruce) and composite panels (particle board (PB), oriented strand board (OSB), and medium density fibreboard (MDF)). Wood-based panels showed more emissive behaviour than solid wood, both for the solid phase and the gas phase. These tests validate the feasibility of generating and measuring particles and emissions of volatile organic compounds (VOCs). Further modifications to the experimental device would enable us to integrate additional devices, such as toxicological ones, to better understand the impact of these wood particles on the health of woodworkers.

“…The rareness of the disease does not allow the exclusion of risk below that concentration (Pesch et al 2008). However, the current occupational exposure limit for inhalable wood dust, based on mass, cannot detect a high exposure to ultra-fine particles (UFP), and particles <10 µm that are easily deposited in the smallest parts of the respiratory system (Gu et al 2018). Woodworkers are estimated to have a 500-fold higher risk of developing sinonasal adenocarcinomas compared to the male population and up to 900 times higher than the general population (Llorente et al 2009).…”

“…Sanding, especially hand sanding, nearly always resulted in inhalable exposures above 5 mg/m 3 (Scheeper et al 1995). Wood processing with high levels of inhalable dust can emit a large number of UFPs and particles <10 µm (Gu et al 2018). Former studies have suggested that sanding with a hand sander is one of the processes that can cause the highest exposure to wood dust.…”

Given the well-known carcinogenicity of hardwood dust, occupational exposure to oak wood dust has been determined in a furniture factory on different wood processing machines during sanding, planing, and milling. Determination of the mass concentrations of respirable and inhalable oak wood dust from ambient air was performed using personal sampling pumps and two types of filter holders: the Higgins-Dewell respirable dust cyclone, manufactured by Casella (Bedford, UK), and the inhalable dust IOM sampler manufactured by SKC (Dorset, UK). Out of a total of 30 values of inhalable mass concentration, 7 (23%) exceeded the occupational exposure level (OEL). The highest exposure levels for inhalable and respirable wood dust from the belt sander were 1.569 to 3.710 mg/m3 and 0.243 to 1.342 mg/m3, respectively. Worker exposure may be below the level of increased risk of 2 mg/m3 if a machine such as a planer or router is connected to a suction system. The share of respirable particles in the inhalable fraction ranged between 12% and 31%, and for samples with an inhalable mass concentration exceeding 2 mg/m3, the share was lower than 16%, with a slightly decreasing tendency. Thus, the risk of lower respiratory tract diseases increases with higher exposure to inhalable particles, and the OEL is an indirect measure of protection against exposure to respirable particles.

“…Such exposures can occur while commuting [22], performing physical activity near a high traffic route [23][24][25], during episodes of high daily average concentrations of fine and ultrafine particles [26,27], and in microenvironments near transport hubs, roadways, underground train stations, and industrial sites [28][29][30][31]. In addition, millions of workers worldwide are daily exposed to processes and tasks associated with the emission of particles at concentrations higher than the typical urban background, such as welding fumes, forest fires, wood dust, and diesel engine exhaust [32][33][34][35], which are known to contribute to mortality by respiratory outcomes [36,37].…”

Background: No study has compared the respiratory effects of environmental and occupational particulate exposure in healthy adults. Methods: We estimated, by a systematic review and meta-analysis, the associations between short term exposures to fine particles (PM2.5 and PM4) and certain parameters of lung function (FEV1 and FVC) in healthy adults. Results: In total, 33 and 14 studies were included in the qualitative synthesis and meta-analyses, respectively. In environmental studies, a 10 µg/m3 increase in PM2.5 was associated with an FEV1 reduction of 7.63 mL (95% CI: −10.62 to −4.63 mL). In occupational studies, an increase of 10 µg/m3 in PM4 was associated with an FEV1 reduction of 0.87 mL (95% CI: −1.36 to −0.37 mL). Similar results were observed with FVC. Conclusions: Both occupational and environmental short-term exposures to fine particles are associated with reductions in FEV1 and FVC in healthy adults.
