Abstract

Abstract Municipal waste plants can be a source of biological contamination of the environment, depending on the method of operation and the type of collected waste. The aim of this study was the quantitative characteristics of airborne microorganisms at the Barycz municipal waste sorting plant in Cracow. Bioaerosol measurements of indoor and outdoor air of the municipal waste sorting plant were performed during the summer season using a six-stage Andersen cascade impactor. The highest concentration of bacterial and fungal aerosol was observed in the medium fraction sorting room (129.02×103 cfu·m-3 and 116.21×103 cfu·m-3, respectively). There were statistically significant differences in the concentrations of bacterial and fungal aerosol between indoor and outdoor air. The calculations showed a significant correlation between the concentration of bioaerosol and particulate matter. Based on the analysis of bioaerosol particle size distribution, it was found that the concentration of bacteria and fungi has a maximum value in the diameter range 3.3-7.0 μm. The study confirmed that the municipal waste sorting plants can be causing exposure to microbiological agents.

都市废物分拣厂的微生物空气质素

城市垃圾处理厂可能是环境的生物污染源，这取决于其操作方法和收集的垃圾类型。本研究的目的是研究克拉科夫Barycz城市垃圾分拣厂空气中微生物的数量特征。在夏季，使用六级安德森级联冲击器对城市垃圾分拣厂的室内和室外空气进行了生物气溶胶测量。细菌和真菌气溶胶浓度最高的是中馏分分拣室(分别为129.02×103 cfu·m-3和116.21×103 cfu·m-3)。室内和室外空气中细菌和真菌气溶胶浓度差异有统计学意义。计算结果表明，生物气溶胶浓度与颗粒物浓度之间存在显著的相关性。通过对生物气溶胶粒径分布的分析，发现细菌和真菌的浓度在直径3.3 ~ 7.0 μm范围内达到最大值。该研究证实，城市垃圾分拣厂可能会导致接触微生物。
