多环芳烃（PAH）（包括联苯）和硝基芳烃的环境浓度进行了测量，在冬季，高氮氧化物事件在南加州的位置。使用Hi-vol过滤器、聚氨酯泡沫（PUF）塞和Tenax-GC固体吸附剂收集日间和高时间环境空气样本。2-硝基芴是最丰富的颗粒相关的硝基芳烃，但较高浓度的1-和2-硝基萘，甲基硝基萘和3-硝基联苯上的PUF插头观察。我们的数据表明，环境浓度的挥发性多环芳烃和硝基芳烃可以远远大于那些挥发性较低的物种，并建议，最丰富的硝基芳烃在环境空气中产生的大气转化体的多环芳烃从燃烧源排放。
The ambient concentrations of polycyclic aromatic hydrocarbons (PAH) (including biphenyl) and nitroarenes were measured during a wintertime, high-NOx episode at a location in Southern California. Daytime and high-time ambient air samples were collected using Hi-vol filters, polyurethane foam (PUF) plugs and Tenax-GC solid adsorbent. 2-Nitrofluroanthene was the most abundant particle-associated nitroarene, but higher concentrations of 1- and 2-nitronaphthalene, methylnitronaphthalenes and 3- nitrobiphenyl were observed on the PUF plugs. Our data show that the ambient concentrations of the more volatile PAH and nitroarenes can be far greater than those of the less volatile species, and suggest that the most abundant nitroarenes in ambient air arise from atmospheric transformants of PAH emitted from combustion sources.
