摘要 于2002年1月至2月在广州市3个点采集不同粒径(PM2.5和PM10)大气气溶胶样品,测定了PM2.5,PM10及其中的有机碳(OC)和元素碳(EC)浓度,探讨了广州市冬季碳气溶胶的污染特征.结果表明,PM2 5和PM10平均浓度分别为105.9 μg/m3及161.7 μg/m3,其中PM25中的OC,EC浓度分别为22.6μg/m3和8.3μg/m3,PM10中的OC,EC浓度分别为29.4和10.4 μg/m3.PM2.5和PM10的总碳气溶胶含量分别为40.5%和35.7%.PM2.5和PM10中OC/EC的比值平均为2.7,这与大多数城市大气的OC/EC比值接近.OC与EC的相关性很好(R>0.9),表明OC与EC的排放源相同.估算的PM2.5中次生有机碳(SOC)平均浓度为12.1μg/m3,占PM2.5中总OC浓度的49.6%;PM10的SOC平均浓度为14.3 μg/m3,占PM10中总OC的44.8%.
