摘要：

Emissions of polycyclic aromatic hydrocarbons (PAHs), elemental carbon (EC), organic carbon (OC), and size distributions of particulate matter from summer tire-concrete road interaction were studied. Based on particle size distribution, particles were categorized in three groups: (1) PM10 (0.02%); (2) PM10-100 (44.20%); and (3) PM100-2,000 (55.78%). The emission factor for total of four PAHs [fluoranthene, phenenthrene, pyrene, and benzo(ghi)perylene] was estimated as 378 ng tire(-1) km(-1) for small cars (engine displacement volume <= 1,000 cm(3); load <= 170 kg tire(-1)). Out of eight PAHS analyzed in particles (all sizes), the main PAH compounds were pyrene (54%) and benzo(ghi)perylene (21%). Emission factors for EC and OC were 1.46 and 2.37 mg tire(-1) km(-1).
