北京地区办公建筑室内颗粒物质量浓度分布特征

Particle mass concentration distribution characteristics in an office building of Beijing

为了研究室内不同粒径颗粒物的质量浓度分布特征,对北京某办公建筑2个不同房间室内与室外颗粒物浓度进行了同步监测。结果显示:建筑室内与室外环境的不同粒径颗粒物的质量浓度均呈现双峰分布,但波峰分布区域不同;室内颗粒物以细颗粒物为主,质量浓度波峰均出现在0~2.5μm粒径范围。

Monitors the particle concentration in two different rooms of an office building and atmosphere in Beijing in order to study mass concentration distribution characteristics of particles with different sizes. The results show that the indoor and outdoor mass concentration of particles with different sizes both have bimodal distribution, but with the different peak. Indoor particles are mainly fine particles, and the mass peaks are in 0 to 2.5 μm zone.
