采用负化学电离气相色谱-质谱联用技术（GC-NCI-MS）同时测定了日本京都收集的汽车尾气颗粒物（NIST SRM 1975和NIES CRM No.8）和大气颗粒物（NIST SRM1648a和PM2.5）中功能化多环芳烃（PAHs），即含氧多环芳烃（OPAHs）、硝化多环芳烃（NPAHs）和氯化多环芳烃（ClPAHs）的浓度。GC-NCI-MS测定的标准物质中多环芳烃衍生物的浓度与认证值和文献值吻合较好。采用该方法在日本京都采集的PM2.5中检测出10种多环芳烃、12种NPAHs和12种ClPAHs。
The concentrations of functionalized polycyclic aromatic hydrocarbons (PAHs), i.e., oxygenated PAHs (OPAHs), nitrated PAHs (NPAHs), and chlorinated PAHs (ClPAHs), in soluble organic fractions of automobile exhaust particles (NIST SRM 1975 and NIES CRM No.8) and airborne particles (NIST SRM1648a and PM2.5 collected at Kyoto, Japan) were simultaneously determined using gas chromatography-mass spectrometry with negative chemical ionization (GC-NCI-MS). The concentrations of PAH derivatives in standard reference materials determined by GC-NCI-MS were in good agreement with the certified and literature values. Ten OPAHs, 12 NPAHs, and 12 ClPAHs were detected in ambient PM2.5 collected in Kyoto, Japan by the proposed analytical method.
