Abstract
With the implementation the strategic layout,the distribution characteristics and diffusion mechanism of aerosol microbes have emerged as a research hotspot,driven by the environmental issues they elicit.In this study,the off-line monitoring method was employed to investigate the concentrations of microbial aerosols in different functional areas of Alar City in Xinjiang,which addresses a critical data deficit pertaining to aerosol pollution in small and medium-sized cities under the new economic development system.The results showed that the seasonal distribution characteristics of total microbial concentrations during the sampling period in Alar City followed the order of spring>autumn>winter>summer.In terms of the distribution characteristics across different functional zones,the concentration sequence was industrial park(6 037.30 CFU∕m3)>residential-commercial mixed zone(5 790.32 CFU∕m3)>educational zone(4 211.10 CFU∕m3)>recreational zone(3 340.02 CFU∕m3).The particle sizes of bacterial and actinomycete aerosols were basically in the range of 0.65-3.30 μm,while the particle sizes of fungal aerosols were consistently maintained at 2.1-1.1 μm.The species abundance of bacteria was much higher than that of fungi during dust events.Therefore,the spatiotemporal distribution characteristics of microbial aerosols were the combined result of meteorological conditions(temperature,humidity,mixing layer height),microbial activity cycles,and human activities.关键词
