| 摘 要： | 利用2002年兰州地区春季背景大气、沙尘天气状况下大气气溶胶的实测资料,得到了不同天气状况下大气气溶胶(TSP)的质量浓度和飘尘(PM10)的粒径分布,着重分析了不同天气状况下大气气溶胶的分布规律及其物理特征.研究发现:TSP中细粒子质量浓度沙尘暴期间比非沙尘暴期间相对减少;背景大气条件下,飘尘对人体健康影响比较严重.

| Abstract: | Asian dust storms carry a large amount of particles from desert areas. The aim of this study is to retrieve data by sampling under different atmospheric conditions such as sand-blowing and dust storm in Lanzhou. The rules of particle size distribution under different conditions were also obtained, with the conclusion that PM10 can be inhaled into the lung of people and other animals, doing harm to their health. |
