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...

Elemental composition of current automotive braking materials and derived air emission factors

Wear-related PM emissions are an important constituent of total PM emissions from road transport. Due to ongoing (further) exhaust emission reduction wear emissions may become the dominant PM source from road transport in the near future. The chemical composition of the wear emissions is crucial information to assess the potential health...

Non-exhaust emissions of PM and the efficiency of emission reduction by road sweeping and washing in the Netherlands

From research on PM_2.5 and PM₁₀ in 2007/2008 in the Netherlands, it was concluded that the coarse fraction (PM_2.5-10) attributed 60% and 50% respectively, to the urban-regional and street-urban increments of PM₁₀. Contrary to Scandinavian and Mediterranean countries which exhibit significant seasonal...
