“…BaP/BghiP ratios ranged The diagnostic ratios obtained in this study implied that traffic emission (from gasoline or diesel engine) and coal combustion were major sources of road dust PAHs. Moreover, in addition to the emissions related to transportation, additional emissions of PAHs due to abrasion of rubber tires, asphalt road surfaces, and brake linings should not be ignored [39,40]. Furthermore, typical combustion emitted PAHs can be indicated by COMB (combustible PAHs species: FLA, PYR, BaA, CHR, BbF, BkF and BbP) [52].…”

“…F. Amato et al: Trends of road dust emissions contributions on ambient PM levels distribution (typically between 1 and 10 µm), causing a high number of the exceedances of air quality limit values at urban and traffic sites. However, road dust is also of concern due to the high content of specific harmful components such as heavy metals and metalloids (i.e., Cu, Sb, Sn, Fe, Zn, Mo;Amato et al, 2009a), sulphides and carbonaceous aerosols such as elemental and organic carbon (EC and OC) and Polycyclic Aromatic Hydrocarbons (PAHs; Pengchai et al, 2004;Majumdar et al, 2012) among others. Heavy metals and sulphides originate from the erosion of brake and tire materials and induce oxidative stress (Yanosky et al, 2012).…”

Abstract. The impact of road dust emissions on PM10 and PM2.5 (atmospheric particulate matter with diameteer < 10 μm and 2.5 μm mass concentrations recorded from 2003 to 2010 at 11 locations (rural, urban and industrial) in southern Spain was estimated based on the chemical characterization of PM and the use of a constrained Positive Matrix Factorization, where the chemical profile of local road dust samples is used as a priori knowledge. Results indicate that road dust increased PM10 levels on average by 21–35% at traffic sites, 29–34% at urban background sites heavily affected by road traffic emissions, 17–22% at urban-industrial sites and 9–22% at rural sites. Road dust contributions to ambient PM levels show a marked seasonality with maxima in summer and minima in winter, likely due to the rainfall frequency. Decreasing concentration trends over the sampling years were found at some traffic and urban sites but in most cases the decreases were less significant than for vehicle exhaust emissions, while concentrations increased at industrial sites, probably due to local peculiarities. Concerning PM2.5, road dust contributions were lower than in PM10, as expected but still important (21–31%, 11–31%, 6–16% and 7% for traffic, urban background, urban-industrial and rural sites, respectively). In addition the three main sources of road dust (carbonaceous particles, brake wear and road wear/mineral) were identified and their contributions to road dust mass loadings estimated, supporting the idea that air quality managers should drive measures aimed at preventing the build-up of road dust particles on roads.

“…As described above, urban road dust contains toxic heavy metals as well as other various toxic chemicals such as polycyclic aromatic hydrocarbons (PAHs), perfluorinated surfactants (PFSs), etc. [53][54][55]. Stormwater runoff brings the road dust to the receiving waterbody and poses the harmful effect to the aquatic lives.…”

Urban dust is contaminated by pollutants from various diffused sources and is often difficult to be controlled. It elevates the background heavy metal exposure level to humans and ecosystems in and around urban area and may give an apparent or hidden impact. In this chapter, the recent studies on heavy metals in the urban dust are summarized. First, the heavy metal pollution of the dust in the atmosphere and on the road surface is described. Then, the process of road runoff and subsequent infiltration to the soil is discussed from the viewpoint of heavy metal mobility. Finally, the ecotoxicity of road dust is shown, and the causal pollutants in the dust are discussed.
