Size-segregated ultrafine particles from motor vehicles were investigated in the Craeybeckx tunnel (E19 motorway, Antwerp, Belgium) at two measurement sites, at 100 and 300 m inside the tunnel, respectively, during March 2008. It was observed that out of the three size modes, nucleation, Aitken, and accumulation, Aitken mode was the most dominant size fraction inside the tunnel. The diurnal variation in ultrafine particle (UFP) levels closely follows the vehicular traffic inside the tunnel…

ON-ROAD VEHICLE FINE PARTICLE EMISSION FROM MEASUREMENT IN A VILNIUS TUNNEL

The fine particle emissions of traffic were investigated in the street tunnel located in the central part of Vilnius city. It was described particle size distribution in the tunnel exit by lognormal

Street Versus Rooftop Level Concentrations of Fine Particles in a Cambridge Street Canyon

Dispersion of particles, as evidenced by changes in their number distributions (PNDs) and concentrations (PNCs), in urban street canyons, is still not well understood. This study compares

Size-resolved emissions of organic tracers from light- and heavy-duty vehicles measured in a California roadway tunnel.

High volume size-resolved PM samples were collected inside the Caldecott tunnel in Orinda, California to determine the relative emission factors for selected PAHs and hopanes in different size ranges, compared to previously conducted PM2.5 emissions testing using dynamometer facilities and other tunnel environments.
