European emission inventories and projections for road transport non-exhaust emissions

The relative contribution of wear emissions to urban road transport PM10 emissions has steadily grown and reaches more than 50% in many countries. Based on reported emissions by European countries for brake and tire wear and road abrasion, an overview of the emissions for Europe is presented and further analyzed for gaps and consistency. Implied...

Improving the modeling of road dust levels for Barcelona at urban scale and street level

Road dust emission is an emerging issue in air quality due to the lack of remediation measures in contrast to vehicle exhaust emissions. The evidence of receptor modeling studies allows for quantifying impact on a few receptors, but the high cost of PM chemical speciation data and the questionable representativeness of single monitoring sites,...

Road dust emission sources and assessment of street washing effect

Although previous studies report on the effect of street washing on ambient particulate matter levels, there is a lack of studies investigating the results of street washing on the emission strength of road dust. A sampling campaign was conducted in Madrid urban area during July 2009 where road dust samples were collected in two sites, namely...

Particle removal in linear shear flow: Model prediction and experimental validation

In many industrial processes, particle contamination is becoming a major issue. Particle detachment from surfaces can be detrimental, e.g., during lithographic processing. During cleaning, however, detachment of particles is aimed for. However, until recently, only little was known on the mechanism of particle detachment due to flowing gasses....

The study of traffic hotspot air quality and street scale modelling in the Street Emission Ceilings (SEC) Project

The introduction of local scale analysis in Integrated Assessment Modelling (IAM) requires an evaluation of road transport emission factors and local scale air quality models. The comparison of PM10 and PM2.5 over NOx delta (street level minus background) concentration ratios against emission ratio estimates, confirms the appropriateness of the...
