摘要
本文测定了北京四合院内4户人家室内空气中可吸入颗粒物的计数浓度,分析了粒径分布,并考察了影响四合院室内可吸入颗粒物污染的不同因素。实验表明,空气内可吸入颗粒以细颗粒为主,粒径小于2.5μm的颗粒物占97%以上,煤球炉是四合院内空气中可吸入颗粒物污染的重要来源。
In this paper, the counter concentration of indoor inhaled particle in 4 families in a courtyard house was measured, and the particle size distribution was analyzed. Furthermore, the factors that would influence the indoor inhaled particle pollution were investigated. The measurement results indicated that most of the particles were belong to submicron particles, and the particles with diameter less than 2.5 microns possessed above 97 %. In addition, it was shown that the burners using coal ball might be the main source for indoor inhaled particle pollution.
