Re-entrained road dust PM10 emission from selected streets of Krakow and its impact on air quality

Abstract

Abstract. Scientific research studies conducted in various parts of the world confirm that PM10 concentrations in urban air depend to a great extent on the resuspension processes of the dust deposited on the road surface. The paper presents the results of the study related to the determination of the re-entrained PM10 emissions from four selected streets of Krakow (Southern Poland) together with the assessment of its impact on air quality. Examined streets are characterised by different traffic intensity (from 500 to over 20 000 vehicles per day) and individual vehicle structure. Dust material sampling and estimation of the PM10 emission were conducted according to the U.S. EPA methodology (AP 42 Fifth Edition). Two variants of sample collection were applied: from the road surface including the area at the curb (4 streets) and from the road surface alone (1 street). The estimates of resuspended road dust emission as well as the reference values derived from the U.S. EPA guidelines were used to assess the impact of this emission on the PM10 levels in the air at the location of one of the analysed streets. This assessment was conducted using the CALINE4 mathematical model. The study showed that the PM10 emissions from the re-entrained road dust can be responsible for up to 25 % in the winter and 50 % in the summer of the total PM10 concentrations in the air near the roads.

Metals concentrations in road dust from high traffic and low traffic area: a size dependent comparison

“…In a study by Patra et al (2008), the determined transfer into the atmosphere of the PM10 fraction of road dust was 40%. Similar values were found in a study by Bogacki et al (2018). Additionally, re-suspension of road dust is significantly reduced in the low-traffic area because of the low-traffic density.…”

“…Traffic-related particulate matter (PM) emissions originate from vehicle tailpipe exhausts as well as from wear of brake pads and discs, tires and the road surface (Loganathan et al 2013). A recent study performed in Krakow (Bogacki et al 2018) demonstrated the importance of the reentrained road dust on PM10, which can be responsible for up to 25% of the total PM10 concentration near the roads during winter and even up to 50% in summer.…”

Assessment of the Variability of Air Pollutant Concentrations at Industrial, Traffic and Urban Background Stations in Krakow (Poland) Using Statistical Methods

“…Moreover, many other studies present long-term trends in changes of air pollutants concentrations in Krakow and their impact on health [74][75][76][77][78][79][80][81][82], the mineralogical composition and microbiological characteristics of aerosols [83,84], the oxidative potential of PM 10 and PM 2.5 [85], the chemical composition of street dust [86] and dry and wet deposition [87][88][89]. The results of measurements from the automatic air quality monitoring station in Krakow were also used to prepare the pollution background necessary in the process of air pollution modeling and the assessment or validation of the dispersion [90][91][92][93][94][95][96][97] or prognostic [98][99][100][101] models used.…”

“…A dozen or so years ago, the combustion of solid fuels (mainly coal) in small furnaces and boilers (related to residential heating) and industrial energy production had the dominant contribution to the high levels of PM 10 in the air in the winter months [72,73]. Thanks to the large-scale elimination of stoves and boilers fired with solid fuels carried out in recent years and replacing them with more ecological energy sources and reducing the emission of pollutants into the air from local industrial plants, emissions from road transport have started to play an increasingly important role for the air pollution in Krakow with regard to fine dust (including engine emission of soot), as well as dust drifted by wind from the road surface and during construction works in dry periods [63,84,[94][95][96].…”

Assessing the Impact of Road Traffic Reorganization on Air Quality: A Street Canyon Case Study

“…Previous works concerning traffic-related air pollutants modeling in street canyons were most often aimed at presenting the impact on air quality of the emissions from selected streets usually located near the air quality monitoring stations. In most cases the CALINE4 [39,40] or OSPM [34,35,[41][42][43] was used in these studies.…”
