Development of lead emission factor for reentrained dust from paved roadways

Conference ·
OSTI ID:6032958
Isokinetic samples of airborne street dust and street dirt loading samples in the Kansas City area were used to derive a combined particulate lead emission factor for vehicle exhaust and re-entrained dust. The results of previous studies were used to reinforce and supplement the conclusions. Particle size analysis showed that lead in vehicle-generated particulate emissions is concentrated in fine particles. The lead content of street dust, which is fairly uniformly distributed across a segment of road, is considerably lower than the lead content of airborne particulates. The lead emission factor for re-entrained dust (0.02 g/vehicle mi) was comparable with the lead emission factor for vehicle exhaust (0.036 g/vehicle mi). Tables.
