| 摘 要： | 用自行研制的中流量PM10～PM2.5大气采样仪,在2004～2005年期间,对杭州市区5个代表性采样点的细颗粒PM2.5污染程度进行监测,结果表明,PM2.5颗粒浓度有着季节性特征,冬季的颗粒浓度明显高于夏季;在繁华马路地区PM2.5污染较为严重,超标率达90%,而在城市绿化较好的地区PM2.5污染较小;PM2.5颗粒浓度与空气湿度呈正相关、与空气能见度呈负相关关系;而且室内外PM2.5颗粒浓度之间也存在一定的相关性,PM2.5/PM10的比值表明对人体健康危害更大的PM2.5占PM10的大部分,在0.50￣0.78范围内。

| Abstract: | The monitoring of PM2.5 conducted in Hangzhou City during the period of 2004-2005 shows that PM2.5 concentration changes with season as well as with location: higher in winter than in summer, and higher in downtown area than in well-afforested area. In addition, ratio of PM2.5 / PM10 is analyzed, ranging from 0.50 - 0.78, which indicates the urban people are more vulnerable to the PM pollution as PM2.5 is regarded being more harmful to health of human being. |
