摘要
采用TSI8520DUSTTRAKAerosolMonitor和TSI8554Q-TRAKIAQMonitor即时采集部分区域环境大气中PM10、PM2.5、PM1.0质量浓度和CO2、CO体积含量,并对颗粒物粒度分布进行回归,分析比较上海市各区域的空气质量.结果表明,环境气溶胶PM10中PM2.5质量百分比为87.28%～96.82%,公交车和主要道路旁的微细颗粒物污染严重.微细颗粒是SRAS病毒的载体,减少SRAS交叉感染首要任务是应提高公众场合针对细微颗粒物的过滤净化水平.
By TSI 8520 DUSTTRAK Aerosol Monitor and TSI 8554 Q-TRAK IAQ Monitor, the mass concentration of ambient aerosol PM_(10), PM_(2.5) and PM_(1.0) and the volume concentration of CO_(2) and CO in some areas are tested. Further more, The size distribution of particles has been regressed. From all of above, the air quality of these areas in Shanghai can be compared. The result shows that the weight percentage of superfine particle PM_(2.5 )is 87.28%～96.82% of ambient aerosol PM_(10), and the air-conditioned buses and the main roads have been polluted severely. Because SARS virus can spread by the superfine particles, the primary study against the cross transmission of severe acute respiratory syndrome (SRAS) should be improving the instruments' performance of filtering superfine particles in public areas.
