Veterinary staff are frequently exposed to various occupational hazards. The present study was aimed to investigate the air characteristics of veterinary clinics in terms of fungal bioaerosols and particulate matters. Air samples were taken every six days from the operating room, examination room and outdoor air of three veterinary clinics in Shiraz, southwest Iran. The concentrations of fungal bio-aerosols ranged from 8.05 CFU/m³ in the outdoor air of clinic B to 47.21 CFU/m³ in the operating room of clinic A. The predominant fungal genera identified in the studied clinics were Penicillium and Aspergillus niger, respectively. The concentrations of PM_2.5 ranged from 41.88 μg/m³ in the operating room of clinic C to 60.31 μg/m³ in the outdoor air of the same clinic. The corresponding values for PM₁₀ ranged from 114.40 μg/m³ in the operating room of clinic C to 256.70 μg/m³ in the outdoor air of the same clinic. The results of this study showed a positive correlation between the concentration of fungal bioaerosols and relative humidity (p < 0.05; r = 0.622). Besides, a negative correlation was found between the concentration of fungal bioaerosols and temperature (p < 0.05; r = 0.369). To better assess the individual exposure of veterinarians and staff in veterinary clinics, tests including nasopharyngeal sampling are recommended.

兽医工作人员经常暴露于各种职业危害中。本研究旨在从真菌生物气溶胶和颗粒物方面调查兽医诊所的空气特征。每六天从伊朗西南部设拉子的三个兽医诊所的手术室、检查室和室外空气中采集空气样本。真菌生物气溶胶浓度从 B 诊所室外空气中的 8.05 CFU/ m ³到A 诊所手术室中的47.21 CFU/ m ^{3不等。在所研究的诊所中鉴定出的主要真菌属是}青霉菌和黑曲霉，分别。PM _2.5浓度范围为 41.88 μg/C诊所手术室的m 3 为60.31 μg/ m ³在^同一诊所的室外空气中。_{PM 10}的相应值范围从诊所C手术室的114.40 μg/ m ³到同一诊所室外空气中的256.70 μg/ m ^{3 。}本研究结果表明，真菌生物气溶胶浓度与相对湿度呈正相关（p < 0.05；r = 0.622）。此外，真菌生物气溶胶浓度与温度呈负相关（p < 0.05；r = 0.369）。为了更好地评估兽医和兽医诊所工作人员的个体暴露情况，建议进行包括鼻咽取样在内的测试。
