| 摘 要： | 利用1998年7月的观测资料，对南京市生物气溶胶浓度垂直分布和日变化规律进行了分析、研究结果表明,生物气溶胶浓度随高度增加逐渐减少;细菌浓度最大值为 700 CFU/m3,真菌浓度最大值为1080 CFU/m3 ,与国内其他一些城市相比,浓度比较低,但与国外有关观测结果相比其真菌浓度要高出许多;细菌、真菌和花粉浓度在于24h内呈现出周期性变化规律. |

| Abstract: | Using the data observed in July 1998, the vertical distribution and variation law of the bioaerosol concentration in Nanjing is analyzed and studied. The result shows that the bioaerosol concentration decreases as the altitude increases; the maximum bacteria concentration is 700 CFU/m3 and that of fungi is 1080 CFU/m3, which are lower than the data of some other domestic cities, but the fungi concentration is obviously higher than that of some foreign cities. The concentrations of farina, bacteria and fungi vary periodically in 24 hours. |
