作者利用12段安德森采样器(<0.13~12.lμ)和高效液相色谱法对室内外2-硝基芴(2-NF)、3-硝基荧蒽(3-NFlr)、1-硝基芘(1-NP)、6-硝基(6.NC)和6-硝基苯并(a)芘(6-NBaP)在悬浮粒子中的粒径分布进行了研究。结果表明,空气颗粒物中的NO2-PAH.75.7%(室外)至87.7%(室内)存在于粒径小于2.5μm的粒子中,室外空气颗粒物中5种NO2-PAH的浓度均高于室内(I/O均值为0.69),但室内空气颗粒上NO2-PAH.的质量浓度高于室外。室内外样本中NO2-PAH.、PAH.和颗粒物浓度相互间以及各项目室内外浓度间几乎均有显著或高度显著性相关。
The authors used 12-segment Anderson sampler (<0.13 ~ 12.lμ) and HPLC to study the effects of 2-NF, 3-NFlr, 1 The particle size distributions of 1-NP, 6-nitro and 6-NBaP in suspended particles were studied. The results show that NO2-PAH in airborne particles. 75.7% (outdoor) to 87.7% (indoor) were present in particles with a particle size of less than 2.5μm. The concentrations of five NO2-PAHs in the outdoor air were higher than those in the room (I / O means 0). 69), but indoor air particles NO2-PAH. The mass concentration is higher than outdoors. Indoor and outdoor samples NO2-PAH. PAH. And the concentration of particulate matter with each other and the concentration of indoor and outdoor items were almost all significant or highly significant correlation.
