摘    要:通过对兰州市城关区1999年春季大气气溶胶的监测,分析了该地区TSP和可吸入颗粒物的质量浓度及可吸入颗粒物的粒径分布规律,并与1993年春季同一时期测得的数据进行了比较。结果表明:该地区TSP的质量浓度日变化呈双峰型;近几年可吸入颗粒物的粒径分布有了明显变化,粗粒子呈下降趋势,细粒子呈上升趋势;气象因子对TSP质量浓度的影响十分明显。

关 键 词:大气气溶胶  可吸入颗粒物  气象因子

Abstract:The pollution of aerosols in the Chengguan District of Lanzhou City in spring of 1999 was monitored. Analyzes of TSP and grain-size distribution of d ust with a comparison with the data of 1993 show that the daily variation of TSP pre sen ts a curve of bi-peaks, and the grain-size distribution of floating dust chang ed great ly in recent years. Climatic conditions have a great effect on the concentration s of TSP.
Keywords:TSP(total suspended pa rticle)  floating dust  climatic conditions
