“…One such procedure will be referred to as a "shot" in the text. Settings used were water delivery stops after 5 s, sample transfer starts after 2 s and the full shot ending at 10 s, as used in previous studies (Gustafsson et al 2019b;Lundberg et al 2019a). Deionized water was used.…”

“…Most of the studies available have been performed in the Nordic countries, focusing on dense pavement, primarily different types of SMA. The most extensive study is presented in Gustafsson et al (2019b) where the mineral dust loads, expressed as DL 180 in Stockholm, Sweden, were studied for 6 years. The study showed a clear seasonal pattern for all investigated streets with lower dust loads in, rather than between, wheel tracks.…”

Resuspension of road dust contributes to air quality issues with resulting health impacts. Limited studies imply that porous pavements can initially mitigate PM10 emissions by acting as a dust trap, but the abrasion wear generates road dust and thus accelerates the clogging processes. In addition, knowledge regarding the impact of pavement types on road dust load dynamics is limited. Road traffic noise can be mitigated using porous pavements, but the use of studded tyres increases the abrasion wear of the pavement as well as increasing the noise emission. Due to this durability problem, porous pavements are rarely used in the Nordic countries where, instead, dense pavements which are abrasion resistant are more common. Linköping municipality, in Sweden, constructed a porous pavement to mitigate road traffic noise. This led to the opportunity to investigate the temporal variation of the dust load dynamics and inherent size distributions over the winter and spring in comparison to those of an adjacent dense pavement. Results, when using the wet dust sampler (WDS) method, showed similar dust load dynamics for the dense and porous pavements. The results were also compared to previous studies using the same method on different dense pavements in Stockholm, Sweden. All locations showed a seasonal variation with higher dust loads during winter and early spring and declining loads towards summer. The size distributions were more complex for the wheel tracks at the porous pavement, having primarily properties of a mixture model compared to the simple size distributions for the dense pavement. On the other hand, the dust load and size distribution were more similar between the porous and dense pavements regarding loads and shapes, indicating a less pronounced but similar behaviour between the surfaces outside of the wheel tracks.

“…The WDS method has been used extensively in national projects for investigations of the temporal and spatial variation of road dust load (Gustafsson et al 2013;Mats Gustafsson et al 2014;Gustafsson et al 2015;Gustafsson et al 2016;Gustafsson et al 2017;Gustafsson et al 2019), evaluation of street cleaning (Gustafsson et al 2011;Janhäll et al 2016;Järlskog et al 2017) and for evaluation of dust binding of paved roads ). The WDS system is currently also used in Norway by the Norwegian Public Roads Administration and in Finland by Nordic Envicon Oy, later by the Finnish Environmental Institute (SYKE), taking the first steps towards a common measurement method to allow for comparable measurements.…”

“…The principle of operation is flushing high-pressurised water over a defined surface area and transferring the dust laden water into a container for further analyses. The WDS has been used for some time and is presented in detail to the international scientific community as reported by Jonsson et al (2008) and Gustafsson et al (2019), and in this paper, the latest version is presented together with an evaluation of its performance. To evaluate the WDS, the ejected water amount was measured, as well as water losses in different parts of the sampling system, together with indicative dust measurement using turbidity as a proxy for dust concentration.…”

In northern countries, the climate, and consequently the use of studded tyres and winter traction sanding, causes accumulation of road dust over winter and spring, resulting in high PM 10 concentrations during springtime dusting events. To quantify the dust at the road surface, a method-the wet dust sampler (WDS)was developed allowing repeatable sampling also under wet and snowy conditions. The principle of operation is flushing high-pressurised water over a defined surface area and transferring the dust laden water into a container for further analyses. The WDS has been used for some time and is presented in detail to the international scientific community as reported by Jonsson et al. (2008) and Gustafsson et al. (2019), and in this paper, the latest version is presented together with an evaluation of its performance. To evaluate the WDS, the ejected water amount was measured, as well as water losses in different parts of the sampling system, together with indicative dust measurement using turbidity as a proxy for dust concentration. The results show that the WDS, when accounting for all losses, have a predictable and repeatable water performance, with no impact on performance based on the variety of asphalt surface types included in this study, given undamaged surfaces. The largest loss was found to be water retained on the surface, and the dust measurements imply that this might not have as large impact on the sampled dust as could be expected. A theoretical particle mass balance shows small particle losses, while field measurements show higher losses. Several tests are suggested to validate and improve on the mass balances. Finally, the WDS is found to perform well and is able to contribute to further knowledge regarding road dust implications for air pollution.

“…The temporal variability of dust emissions is also affected by the meteorological conditions, due to rainfall and high humidity inhibiting its emission (Amato et al, 2014). According to Gustafsson et al (2019), the road dust load is usually the highest from mid-winter to early spring, while the lowest occurs in early autumn and late spring. According to Amato et al (2017), traffic volume and vehicle speed on the street affect the amount of road dust remaining on the surface.…”

The aim of the study was to assess the content of Ca, Mg, Na and K in the road dust collected in Białystok from various environments (roads with high traffic intensity, housing estate roads, roads located near parks and green areas), in order to determine the impact of the road transport on the spatial differentiation of the content of the tested components in street dust and identify their main sources. In total, the samples from 69 points were analyzed, which were taken in spring 2018 (late April and May) during the dry weather. The content of Ca, Mg, Na and K was determined by means of atomic absorption spectrometry (AAS). The average contents of the tested elements in the dust from all measuring points were in the following order: Ca (23.53%) > Mg (2.38) > Na (1.16) > K (0.25). This shows that Ca is the most numerous element in the tested dusts. Studies have not shown a significant impact of vehicle traffic, in particular the so-called non-exhaust sources related to this traffic on the content of main elements in the Białystok road dusts. The analyses have indicated that the main source of Ca and Mg in the Białystok road dust constitute the structural elements of roads, bridges and structures, in which building cement and its derivatives are the main component.
