建立了大气中低浓度的17种硝化多环芳烃（NPAH）和9种氧化多环芳烃（OPAH）的气相色谱-质谱-负离子化学电离（GC/NICI-MS）分析方法。该方法包括固相萃取（SPE）柱上的液相色谱纯化程序。该分析方法的应用已在标准参考物质（SRM 1649 a：城市灰尘）上进行，得到的结果与文献中的少数数据吻合良好。分析方法也适用于环境空气样品（气相和颗粒相）从法国POVA计划（POllution des Vallees Alpines）。在冬季，在一个农村地区观测到的非多环芳烃浓度在颗粒相中约为0.2-100.0 pg m（-3），在气相中约为0.0-20.0 pg m（-3）。OPAH的浓度高出10- 100倍（颗粒物和气相分别为0.1-2.0 ng m（-3）和0.0-1.4 ng m（-3））。这些初步结果表明，取样地点的特征与化合物来源（原生或次生）之间存在良好的相关性。(c)2006 Elsevier B.

This study deals with the development of a routine analytical method using gas chromatography-mass spectrometry with negative ion chemical ionisation (GC/NICI-MS) for the determination of 17 nitrated polycyclic aromatic hydrocarbons (NPAHs) and 9 oxygenated polycyclic aromatic hydrocarbons (OPAHs) present at low concentrations in the atmosphere. This method includes a liquid chromatography purification procedure on solid-phase extraction (SPE) cartridge. Application of this analytical procedure has been performed on standard reference material (SRM 1649a: urban dust), giving results in good agreement with the few data available in the literature. The analytical method was also applied on ambient air samples (on both gas and particulate phases) from the French POVA program (POllution des Vallees Alpines). NPAHs concentrations observed for a rural site during the Winter period are about 0.2-100.0 pg m(-3) in the particulate phase and about 0.0-20.0 pg m(-3) in the gas phase. OPAHs present concentrations 10- 100 times higher (0.1-2.0 ng m(-3) and 0.0-1.4 ng m(-3) for the particulate and the gas phases, respectively). These preliminary results show a good correlation between the characteristics of the sampling site and the compound origins (primary or secondary). (c) 2006 Elsevier B.V. All rights reserved.
