Microbiological air sampling was performed in 2 furniture factories located in eastern Poland. In one factory furniture were made from fibreboards and chipboards while in the other from beech wood. It was found that the concentration of total microorganisms (bacteria + fungi) in the air of the facility using beech wood for furniture production (mean 10.7 x (3) cfu/m(3), range 3.3 27.5 x (3) cfu/m(3)) was significantly higher (p < 0.01) compared to microbial concentration in the facility using fibre- and chipboards (mean 3.6 x (3) cfu/m(3), range 1.9-6.2 x (3) cfu/m(3)). On average, the commonest microorganisms in the air of the furniture factories were corynebacteria (Corynebacterium spp., Arthrobacter spp., Brevibacterium spp.) which formed 18.1-50.0% of the total airborne microflora, and fungi (mostly Aspergillus spp., Penicillium spp., Absidia spp. and yeasts) which formed 6.2-54.4% of the total count. The values of the respirable fraction of airborne microflora in the furniture factories varied within fairly wide limits and were between 15.0-62.4%. Altogether, 28 species or genera of bacteria and 12 species or genera of fungi were identified in the air of examined factories, of which respectively 8 and 7 species or genera were reported as having allergenic and/or immunotoxic properties. In conclusion, the workers of furniture factories are exposed to relatively low concentrations of airborne microorganisms which do not exceed the suggested occupational exposure limits. Nevertheless, the presence of allergenic and/or immunotoxic microbial species in the air of factories poses a potential risk of respiratory disease, in particular in sensitive workers.
在波兰东部的两家家具厂进行了微生物空气采样。其中一家工厂的家具由纤维板和刨花板制成，另一家则由山毛榉木制成。结果发现，使用山毛榉木生产家具的工厂空气中总微生物（细菌+真菌）浓度（平均10.7×10³ cfu/m³，范围3.3 - 27.5×10³ cfu/m³）显著高于（p < 0.01）使用纤维板和刨花板的工厂中的微生物浓度（平均3.6×10³ cfu/m³，范围1.9 - 6.2×10³ cfu/m³）。平均而言，家具厂空气中最常见的微生物是棒状杆菌（棒状杆菌属、节杆菌属、短杆菌属），占空气微生物群落总数的18.1 - 50.0%，以及真菌（主要是曲霉属、青霉属、犁头霉属和酵母菌），占总数的6.2 - 54.4%。家具厂空气中可吸入微生物部分的值在相当宽的范围内变化，为15.0 - 62.4%。在所检查的工厂空气中总共鉴定出28种或属的细菌和12种或属的真菌，其中分别有8种和7种或属被报告具有致敏和/或免疫毒性特性。总之，家具厂工人接触到的空气中微生物浓度相对较低，未超过建议的职业接触限值。然而，工厂空气中存在致敏和/或免疫毒性微生物物种对呼吸系统疾病构成潜在风险，尤其是对敏感工人。
