摘　　要：于2011年12月15日～12月21日,利用武汉天虹TH-16A型四通道大气颗粒物采样器、美国赛默飞TEOM1405型在线颗粒物监测仪、美国Andersen 240型双通道采样器、北京地质仪器厂PM2.5-2型颗粒物采样器、武汉天虹TH-150A型中流量采样器PM2.5和PM10进行连续的手动和自动观测。结果表明:TH-16A、PM2.5-2与Andersen 240型PM2.5采样器平行样之间有良好的相关性,R2值分别为0.973 5、0.914 4、0.885;PM10的采样器中,TH-150A的平行样相关性最高,达到了0.997。Andersen 240的PM2.5、PM10监测数据均高于TEOM 1405,这可能是因为TEOM天平室的高温环境(50℃),导致了颗粒物中部分有机物组分的挥发。PM2.5采样器中,PM2.5-2监测结果与TEOM 1405最为接近,二者相关性最高。PM10采样器中,TH-150A与TEOM 1405的监测结果偏差最小,相关性最高,达到0.974。A comparison has been performed on the collection of PM2.5 and PM10 by several particle samplers,i.e.,Tian Hong Model 16A four-channel mass sampler(Wuhan),Thermo Scientific TEOM-1405(USA),Andersen Model 240 dual channel mass sampler(USA),Geological Instrument Factory Model PM2.5-2 sampler(Beijing),Tian Hong Model 150A mass sampler(Wuhan).The results showed that,the PM2.5 samples from TH-16A,PM2.5-2 and Andersen 240 had a good correlation,and the R2 was 0.973 5,0.914 4,0.885,respectively,while the PM10 samples from TH-150A had the highest correlation(0.997).The data for PM2.5 & PM10 monitored by Andersen Model 240 dual channel mass sampler were higher than those monitored by TEOM 1405,and this may be due to the hot balance room(50 ℃) in TEOM-1405,leading to some semivolatile matters be lost.Among PM2.5 samplers,the results obtained with Model PM2.5-2 were the closest to those with TEOM-1405.Among PM10 samplers,the results obtained with TH-150A had the highest correlation coefficient(0.974) with those with TEOM-1405.
