Abstract

ABSTRACT: 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.
