Abstract. Oxidative potential (OP) is an emerging health-related metric which integrates several physicochemical properties of particulate matter (PM) that are involved in the pathogenesis of the diseases resulting from the exposure to PM. Daily PM2.5-fraction aerosol samples collected in the rural background of the Carpathian Basin and in the suburban area and centre of its largest city of Budapest in each season over one year were utilised to study the OP at the related locations for the first time. The samples were analysed for particulate matter mass, main carbonaceous species, levoglucosan and 20 chemical elements. The resulted data sets were subjected to positive matrix factorisation to derive the main aerosol sources. Biomass burning (BB), suspended dust, road traffic, oil combustion, vehicle metal wear and mixed industrial source were identified. The OP of the sample extracts in simulated lung fluid was determined by ascorbic acid (AA) and dithiothreitol (DTT) assays. The comparison of the OP data sets revealed some differences in the sensitivities of the assays. In the heating period, both the OP and PM mass levels were higher than in spring and summer, but there was a clear misalignment between them. In addition, the heating period-to-non-heating period OP ratios in the urban locations were larger than for the rural background by a factor of 2–4. The OP data sets were attributed to the main aerosol sources using multiple linear regression with the weighted least squares approach. The OP was unambiguously dominated by BB at all sampling locations in winter and autumn. The joint effects of motor vehicles involving the road traffic and vehicle metal wear played the most important role in summer and spring, with considerable contributions from oil combustion and resuspended dust. In winter, there is temporal coincidence between the most severe daily PM health limit exceedances in the whole Carpathian Basin and the chemical PM composition causing larger OP. Similarly, in spring and summer, there is a spatial coincidence in Budapest between the urban hotpots of OP-active aerosol constituents from traffic and the high population density in central quarters. These features offer possibilities for more efficient season-specific air quality regulations focusing on selected aerosol sources rather than on PM mass in general.

“…S1). It also contained Cl, Br, Zn and Pb, which could originate from agricultural-waste and household-waste burnings, including (illegal) burnings of some solid materials such as plastics, furniture, fibreboards, tyres and coloured paper together with biomass (Hoffer et al, 2021). Its intensity was the largest in winter, substantial in autumn and very low in spring and summer.…”

S1 In situ measurements and dataConcentrations of NO/NOx(=NO+NO2), CO, O3 and SO2 were obtained from the Hungarian Air Quality Network (Salma et al., 2020a). They were determined by chemiluminescence (Thermo 42C), IR absorption (Thermo 48i), UV absorption (Ysselbach 49C) and UV fluorescence (Ysselbach 43C) methods, respectively with a time resolution of 1 h. In the rural background and suburban area, the concentrations were obtained directly at the sampling locations. In the city centre, the pollutants were measured in 4.5 km in the upwind prevailing direction from the sampling site.In the city centre, particle number size distributions were also determined by a flow-switching-type differential mobility size spectrometer in a diameter range from 6 to 1000 nm in 30 channels in the dry state of particles with a time resolution of 8 min (Salma et al., 2016). Concentrations in several size fractions were calculated. Of them, the daily mean concentrations of the total particles (N6−1000) and of particles in the diameter range of 25−100 nm (N25−100) were used here. The latter concentration is often associated with emission sources from vehicles (Salma et al., 2020b).Local air temperature (T) and relative humidity (RH) data were acquired by standardised meteorological methods (anemometer HD52.3D17, Delta OHM, Italy or Vaisala HMP45D and Vaisala WAV15A, Finland) on sites with a time resolution of 1 min (Salma et al., 2022).

The samples were analysed for particulate matter mass, main carbonaceous species, levoglucosan and 20 chemical elements. The resulting data sets were subjected to positive matrix factorisation to derive the main aerosol sources. Biomass burning (BB), suspended dust, road traffic, oil combustion mixed with coal combustion and long-range transport, vehicle metal wear, and mixed industrial sources were identified. The OP of the sample extracts in simulated lung fluid was determined by ascorbic acid (AA) and dithiothreitol (DTT) assays. The comparison of the OP data sets revealed some differences in the sensitivities of the assays. In the heating period, both the OP and PM mass levels were higher than in spring and summer, but there was a clear misalignment between them. In addition, the heating period : non-heating period OP ratios in the urban locations were larger than for the rural background by factors of 2–4.

In winter, there is temporal coincidence between the most severe daily PM health limit exceedances in the whole Carpathian Basin and the chemical PM composition causing larger OP. Similarly, in spring and summer, there is a spatial coincidence in Budapest between the urban hotspots of OP-active aerosol constituents from traffic and the high population density in central quarters. These features offer possibilities for more efficient season-specific air quality regulations focusing on well-selected aerosol sources or experimentally determined OP, rather than on PM mass in general.
