摘要
分别在冬季及夏季选取具有典型气候特性的两天,采集空气中总悬浮颗粒物(TSP)。根据采样前、后滤膜重量之差及采样标况体积,计算TSP质量浓度,采用液相沉降法测定粒度分布,对环境空气中总悬浮颗粒物(TSP)和可吸入颗粒物(PM10)进行粒度分布相对百分比及粒度分布累计研究。分析总悬浮颗粒物(TSP)中含有的粒度分布情况及冬夏两季可吸入颗粒物(PM10)与总悬浮颗粒物(TSP)的比例关系。更深一步了解TSP各级颗粒的粒度分布,特别是PM10以下的颗粒物的粒度分布情况。
Total suspended particles （TSP） were collected respectively on a selected summer day and a winter day with typical climate characteristics, the mass concentration of TSP was calculated according to the weight difference of filter membrane before and after sampling and sampled volume, and relative percentage of particle size distribution and accumulation of size distribution of TSP and PM10 in the ambient air was determined and studied by liquid setting method. The particles size distribution of TSP and the proportion relation between PM10 and TSP in the winter months and the summer months was analyzed. The size distribution of various particles in TSP, especially those below PM10 were learned further.
