“…These differences are due to the fact that about 90% of all the heavy metals from non-exhaust emission are contributed to the fraction with a grain size of < 20 µm (Adamiec et al 2016 ). This agrees with the results of our previous study (Dytłow et al 2019b ) on the magnetic and chemical properties of different granulometric fractions of street dust in Warsaw. It was found that the two finest fractions with a diameter of “0.1 mm–71 μm” and “ < 71 μm” had the smallest contribution to the total mass of dust, but contained the highest concentrations of Fe, Cr, Cd, Co, Zn, Pb, Ni, Mn, Cu, and Al.…”

“…Our research and experience (e.g. Dytłow et al 2019a ) shows that magnetic susceptibility has the potential to be used to screen the great assemblage samples as it is strongly correlated with the concentration of traffic-related heavy metals.…”

“…The analysis was conducted on a subset of 23 samples obtained from a set of 248 samples of street dust collected during the summer of 2013 and 2014 from the road surfaces of the city of Warsaw, Poland. The properties of all 248 samples have been evaluated in previous our works in terms of concentration of anthropogenic magnetic particles, their mineralogy, and the state of the domain using magnetic methods (Dytłow and Kostrubiec 2018 ; Dytłow et al 2019b ). Detailed information about the sampling area and the collection method can be found in Dytłow and Kostrubiec ( 2018 ) and Dytłow et al ( 2019b ).…”

Geochemical background data are used to distinguish between the sources of heavy metal (natural or anthropogenic) and to categorize the level of heavy metal pollution. In this study, we present the results of using different geochemical backgrounds (BG1–BG3) to establish the level of heavy metal pollution in street dust in Warsaw, Poland. We applied individual and collective indicators calculated with respect to the following backgrounds: (1) upper continental crust (UCC) (BG1), (2) the regional geochemical background established for Quaternary surface deposits of the Mazovian region (Poland) (parent geological material occurring in the studied area, Warsaw, Poland) (BG2), and (3) the minimal values of the concentration of heavy metals determined for the real street dust sample collectives from Warsaw (BG3). The assessment of the heavy metals pollution of street dust significantly depended on the background values used in the calculation of individual and collective indicators. Street dust was classified as unpolluted for almost all the heavy metals based on the values of indicators calculated for UCC data. The effect of traffic-related pollution was detected more precisely based on the values of indicators calculated for BG2 and BG3. The naturally elevated concentrations of heavy metals in UCC data can be responsible for the underestimation of pollution impact in street dust. When relatively low concentration of heavy metals is only observed, the application of BG2 or BG3 background data, which better correspond to the geogenic material in street dust, allows to realistically reflect the level of pollution from moving vehicles.

“…The hazard index of magnetic particles in pollution combined with iron and other heavy metals in Thessaloniki, Greece (Bourliva et al, 2016) and Yunnan, China (Tan et al, 2018) were either higher than or very close to the safe level. Evidently, Magnetic minerals in polluted dust enriched with heavy metals have been identi ed in Thessaloniki, Greece (Bourliva et al, 2016), Warsaw, Poland (Dytłow et al, 2019), Morelia, Mexico (Aguilar Reyes et al, 2013) and Ostrava, Czechia (O'Shea et al, 2020) using SEM-EDS. A signi cant amount of iron oxides with variable surface charge and high redox activity have been traced in the human brain (Dlháň et al, 2019).…”

Sources of magnetic phases in urban dust include traffic-related activities, industrial products and detrital minerals. Exposure to magnetic phases in urban dust co-associated with trace metals is associated with respiratory ailments in sensitive organisms. Here, we collected samples of surface roadside dust and topsoil from Xiamen island, Fujian, China and then magnetic properties were determined using rock-magnetic methods. Magnetic particle concentrations in surface roadside dust was found to be significantly high compared with magnetic content in topsoil using magnetic susceptibility (𝜒LF), saturation isothermal remanent magnetization (SIRM) and susceptibility of anhysteretic remanent magnetization (𝜒ARM). Roadside dusts had much lower percent frequency-dependent susceptibility (1.83 ± 0.12%) than topsoil (2.96 ± 0.14%). Given the 𝜒ARM/SIRM vs 𝜒fd% and first-order reversal curves, most of the magnetic particles in roadside dust were large than in topsoil. Variable temperature dependence of magnetization, isothermal remanent magnetization decomposition spectra and first-order reversal curves suggested the enhancement of dust 𝜒LF, SIRM and 𝜒ARM were related to the exogenous pseudo-single-domain magnetite-like materials. This study provides a better understanding of magnetic ageing of dust particles in coastal cities. These results will be useful in optimizing environmental policies aimed at regulating magnetic dust particles pollution in coastal cities.

Industrial and urban dusts were characterized by investigating their magnetic properties. Topsoil composed of technogenic magnetic particles (TMP) originating from areas affected by three ironworks, street dust mainly composed of traffic-related pollution, and particulate matter (PM) from urban agglomeration in Warsaw, Poland were investigated. Several magnetic methods, namely magnetic susceptibility, thermomagnetic curves, hysteresis loops, decomposition of isothermal remanent magnetization acquisition curves, and first-order reversal curves, were performed to evaluate the magnetic fraction of dust. Magnetite was the main magnetic phase in all types of samples, with a small amount of high-coercive hematite within ironworks and street dust samples. Significant differences were observed in the domain structure (grain size) of industrial and traffic-related magnetic particles. The grain size of TMP obtained from steel production was in the range of 5–20 µm and was predominated by a mixture of single-domain (SD) and multidomain (MD) grains, with the prevalence of SD grains in the topsoil affected by Třinec ironwork. The traffic-related dust contained finer grains with a size of about 0.1 µm, which is characteristic of the pseudo-single-domain (PSD)/SD threshold. Street dusts were composed of a slightly higher proportion of MD grains, while PM also revealed the typical behavior of superparamagnetic particles.
