Abstract: The dust emission during woodworking results in the air pollution with both particulate and microbial aerosols. The aim of this study was to assess a degree of contamination of joinery workplaces with dust, bacteria, fungi, endotoxins, and (1→3)-β-D-glucans released into the air during wood processing and check whether these conditions provoke any changes in cytological picture of nasal lavage fluid in workers after their exposure to studied contaminants. The maximal concentrations of studied pollutants were 3.5mg/m3, 11473cfu/m3, 3348cfu/m3, 3.5ng/m3 and 394.6ng/m3, respectively. Exposure to high concentrations of wood dust and (1→3)-β-D-glucans may trigger pathogenic reactions in exposed individuals. Stationary measurements of bioaerosols are poor proxy for workers exposure, hence hygienic evaluation of microbiological hazards in this working environment should be based on personal sampling. The analysis of nasal lavage fluid confirms its usefulness as reliable analytical tool for assessing the health status of joinery workers exposed to harmful biological agents.
