摘    要:用大流量冲击式分级采样器采集大气颗粒物样品,通过重量法求出不同粒径颗粒物的质量,研究不同粒径颗粒物的质量百分比.分析不同粒径颗粒物与风速、温度、湿度等气象条件的变化规律.结果表明:各级颗粒物整体与温度和风速呈负相关性,与湿度呈正相关性,且粒径小于2.1 μm的颗粒物与湿度相关性最大.大气颗粒物主要集中在2.1 μm以下...

关 键 词:大气颗粒物  不同粒径  变化特征  气象条件

Abstract:Air particles were collected by high volume cascade impact sampler.The quality of different diameters of air particles were measured by gravimetric method and mass percentage was studied.Variation feature of different diameters of air particles and wind speed,temperature and humidity was analyzed.Results showed that different diameters of air particles have negative correlation with temperature and wind speed,while positive correlation with humidity.And particles less than 2.1 μm have the most correlation with humidity.These particles mainly concentrated in the range less than 2.1μm have bad impact to human body.
Keywords:air particles  different diameters  variation feature  meteorological condition
