“…Several factors are reported to affect non-exhaust emissions including increase in vehicle speed (Chen et al, 2006;Gustafsson et al, 2008;Hussein et al, 2008;Mathissen et al, 2011) although Keuken et al (2010) reported a non-linear relationship between traffic volume and non-exhaust emissions. Metal emissions due to road dust show a low correlation to metal emissions due to abrasion/brake wear and combustion (Johansson et al, 2009).…”

Road traffic is one of the main sources of particulate matter in the atmosphere. Despite its importance, there are significant challenges in quantitative evaluation of its contribution to airborne concentrations. This article first reviews the nature of the particle emissions from road vehicles including both exhaust and non-exhaust (abrasion and resuspension sources). It then briefly reviews the various methods available for quantification of the road traffic contribution. This includes tunnel/roadway measurements, twin site studies, use of vehicle-specific tracers and other methods. Finally, the application of receptor modelling methods is briefly described. Based on the review, it can be concluded that while traffic emissions continue to contribute substantially to primary PM emissions in urban areas, quantitative knowledge of the contribution, especially of nonexhaust emissions to PM concentrations remain inadquate.

“…Fe has been found in high concentrations (11,000–94,000 ppm) in the submicrometer fraction of roadside PM . Fe-bearing NPs are frequently associated both with transition and heavy metals, including Cr, Ni, Cu, Zn, Pb, Mn. ,, Most of the Fe-bearing particles emitted from vehicles are ferromagnetic ( sensu lato ) Fe oxides, comprising mixtures of strongly magnetic magnetite (Fe 3 O 4 ), its oxidized counterpart, maghemite (γ-Fe 2 O 3 ) and hematite (α-Fe 2 O 3 ), with some metallic Fe (α-Fe) also reported. ,− The magnetic ordering shown by these airborne Fe-oxide particles enables their measurement and quantification using a range of concentration- and particle size-dependent magnetic analyses (see Section ).…”

Airborne particulate matter poses a serious threat to human health. Exposure to nanosized (<0.1 μm), vehicle-derived particulates may be hazardous due to their bioreactivity, their ability to penetrate every organ, including the brain, and their abundance in the urban atmosphere. Fe-bearing nanoparticles (<0.1 μm) in urban environments may be especially important because of their pathogenicity and possible association with neurodegenerative diseases, such as Alzheimer’s and Parkinson’s diseases. This review examines current knowledge regarding the sources of vehicle-derived Fe-bearing nanoparticles, their chemical and mineralogical compositions, grain size distribution and potential hazard to human health. We focus on data reported for the following sources of Fe-bearing nanoparticles: exhaust emissions (both diesel and gasoline), brake wear, tire and road surface wear, resuspension of roadside dust, underground, train and tram emissions, and aircraft and shipping emissions. We identify limitations and gaps in existing knowledge as well as future challenges and perspectives for studies of airborne Fe-bearing nanoparticles.

“…In order to get chemical profiles of dust, the resuspension method has been used to collect PM 10 and PM 2.5 samples from different fugitive dust sources (Chow et al, 1994;Vega et al, 2001). However, most studies focused on road dust (RD) (Wang et al, 2005;Chen et al, 2006;Han et al, 2011;Shen et al, 2016), soil dust (SD) (Ho et al, 2003;Kong et al, 2011;Liu et al, 2016) and cement (CE) (Vega et al, 2001;Ho et al, 2003). Unfortunately, few chemical profiles on demolition dust (DD) are existent, although heavy metals in ambient air contaminated from DD have been evaluated for health risk assessment (Farfel et al, 2003;Brown et al, 2015a;Azarmi and Kumar, 2016).…”

As a result of rapid urbanization, the road lengths and built-up areas in Zhengzhou are steadily expanding along with increasing fugitive dust emissions. Identifying the physical and chemical characteristics and the chemical profiles of fugitive dust is important in achieving effective atmospheric pollution management. In this study, soil dust, road dust (RD), building demolition dust, and cement (CE) were chosen as the research objects. A total of 94 dust samples were collected from 20 sites. PM 2.5 (particulate matter with diameter ≤ 2.5 µm) and PM 10 (particulate matter with diameter ≤ 10 µm) samples were obtained by using a re-suspension device and their physical and chemical properties were analyzed. The scanning electron microscopy of four types of dust particles showed that most of the dust particles presented an irregular shape. In terms of particle size distribution, the mass concentration of PM 2.5 accounted for less than 10% of the total PM 10 , whereas the number concentration of PM 2.5 accounted for more than 96% of the total number. Chemical component analysis revealed that crustal elements such as Al, Mg, Fe, and K were abundant in all samples, and they were the most abundant species in PM 2.5 and PM 10 in the reconstruction results. The percentage of NO 3 -in the RD sample was higher than that in the other three fugitive dust samples because of the influence of vehicles. Furthermore, the CE sample had higher SO 4 2-and Ca 2+ percentages than the other three types of fugitive dust samples. Enrichment factor analysis showed that the significant enrichment of Cd and Ag was mainly caused by anthropogenic sources. The coefficients of divergence values between the profiles for different sites of dust ranged from 0.21 to 0.68, indicating the fugitive dust profiles from various sites mostly different. The chemical profiles of four dust sources obtained from this study is limited in Zhengzhou.
