摘要：

Standardised tests were performed on four light-duty diesel vehicles running in a chassis dynamometer at a vehicular emission laboratory, using the FTP-75 test cycle procedure. The aim was to characterise emissions of Polycyclic Aromatic Hydrocarbons (PAHs), substances that create health hazards and are, as yet, unregulated. The pollutants were analysed in both solid and gaseous phases using high-performance liquid chromatography. Total PAH values ranged from 1.133 to 5.801 mg km(-1). Naphthalene, phenanthrene, fluoranthene, pyrene and chrysene were detected in all tests. In addition, PAH emission was observed to be inversely related to emission Of CO2. (C) 2003 Elsevier Ltd.
