| 中文摘要 |
| 大学宿舍室内生物气溶胶可通过空气传播,可能会危害学生身体健康. 本研究调查了梅雨期大学宿舍室内生物气溶胶浓度和粒径分布特点,对其同空气颗粒物浓度、环境温度和湿度的Spearman相关性进行了研究,分析了学生活动对宿舍室内气溶胶的影响. 结果表明,学生宿舍室内的细菌和真菌气溶胶平均浓度分别为(2133±1617) CFU ·m-3和(3111±2202) CFU ·m-3,真菌气溶胶的浓度明显高于细菌. 学生宿舍室内的PM1、PM2.5、PM10与细菌气溶胶浓度呈负相关,与真菌气溶胶浓度呈显著负相关; PM2.5与可吸入细菌气溶胶呈正相关,PM10与可吸入真菌气溶胶呈正相关; 环境温度与细菌和真菌气溶胶浓度呈正相关,环境相对湿度与细菌和真菌气溶胶浓度呈负相关. 在下午,宿舍室内真菌气溶胶浓度显著增加,上午和下午生物气溶胶的粒径分布有差异. 本研究结果将为评价高校学生宿舍室内空气质量提供基础数据. |
| 英文摘要 |
| Bioaerosols of university dormitory can spread through air and cause a potential health risk for student staying in indoor environment. To quantify the characteristics of bioaerosols in indoor environment of university dormitory, concentration and size distribution of culturable bioaerosols were detected during the plum rain period,the correlations of culturable bioaerosol with concentration of particulate matter, the ambient temperature and relative humidity were analyzed using Spearman's correlation coefficient and finally the changes of size distribution of culturable bioaerosol caused by activities of students were detected. The results showed that the mean concentrations of culturable airborne bacteria and fungi were (2133±1617) CFU ·m-3 and (3111±2202) CFU ·m-3. The concentrations of culturable airborne bacteria and fungi exhibited negative correlation with PM1, PM2.5 and PM10, respectively. The respirable fractions of bacteria exhibited positive correlation with PM2.5, and the respirable fractions of fungi exhibited significant positive correlation with PM10. Ambient temperature had positive correlation with culturable airborne bacteria and fungi, and relative humidity had negative correlation with culturable airborne bacteria and fungi. In the afternoon, concentrations of culturable airborne fungi in indoor environment of university dormitory significantly increased, and the size distribution of culturable bioaerosols was different in the morning and afternoon. |
