The air from a house and garden in a rural area has been sampled and the size distributions of the airborne particles have been determined. The particle concentrations are shown to be generally higher indoors. Changes in the particle concentration during various activities in a small room have been shown to be greatest for particles larger than 3 mum. diameter. Stereoscan microscopic observation has shown that many of the airborne particles in rooms and some from those in outside air appear to be scales of desquamated skin. The presence of protein in many of these particles complements the microscopic observations.
对农村地区一所房屋和花园中的空气进行了采样,并测定了空气中颗粒物的粒径分布。结果表明,室内颗粒物浓度普遍较高。在一个小房间内进行各种活动时,直径大于3微米的颗粒物浓度变化最大。立体扫描显微镜观察表明,室内许多空气中的颗粒物以及一些室外空气中的颗粒物似乎是脱落的皮肤鳞片。这些颗粒物中许多含有蛋白质,这与显微镜观察结果相符。
