摘要/Abstract

摘要：

于2014 年2—3 月和11—12 月对室内外环境中细颗粒物进行采集和分析, 研究通风条件、大气污染水平以及温、湿度等因素对细颗粒物室内外关系的影响。研究表明, 通风条件和大气污染水平是影响细颗粒物室内外关系的重要因素, 对细颗粒物的 I/O、室内外相关系数、细颗粒物的渗透因子以及大气细颗粒物对室内的贡献率均有影响, 通风条件越好, I/O 越高, 室内外相关系数和室外贡献率也越大; 随着大气细颗粒物浓度的升高, 细颗粒物 I/O 比值有升高的趋势, 且其波动范围逐渐减小, 室内外细颗粒物之间的相关性逐渐增强, 室外贡献率逐渐增大, 但增速逐渐减缓。温、湿度均对细颗粒物室内外关系的影响较小。

关键词: 室内外关系, 细颗粒物, 相关系数, I/O, 室外贡献率

Abstract:

Indoor and outdoor fine particulate matter were sampled and analyzed in Feb.–Mar. and Nov. –Dec., 2014. The influence of ventilation condition, atmospheric pollution level, the temperature and humidity on relationship between the indoor and outdoor fine particulate matters were studied. Studies showed that ventilation and air pollution levels were two important factors affecting the indoor and outdoor relations of PM2.5, they both had effects on I/O ratio, correlation coefficient of indoor and outdoor particles as well as the contribution rate of the atmospheric PM2.5 concentrations on the indoor PM2.5 concentrations. With better ventilation condition or higher I/O ratio, indoor and outdoor correlation coefficient would be higher, as well as the outdoor contribution rate. When the atmospheric PM2.5 concentration went higher, the I/O ratio, indoor and outdoor correlation coefficient and outdoor contribution rate became higher, while the range of I/O ratio and the growth rate of outdoor contribution went less. The temperature and humidity had little effect on indoor and outdoor relations of PM2.5.

Key words: indoor and outdoor relationship, PM2.5, correlation coefficient, I/O, outdoor contribution
