“…The concentrations of elements in URD in this study were compared to different sites in the world(Table 7)[18,[23][24][25][26][74][75][76]. Mn, Cr, Mg, Rb, Ba, and Al are crustal elements; Zn, As and Cu may originate from fuel combustion, traffic activities, domestic heating and industrial emissions; and Ni may derive from the large furnaces used to make alloys, power plants and trash incinerators [18,[23][24][25][26][74][75][76]…”

Selected Metals in Urban Road Dust: Upper and Lower Silesia Case Study

et al. 2020

In this study, urban road dust (URD) samples were collected in two populated agglomerations of Wrocław and Katowice (Lower and Upper Silesia) in Poland. Both the total concentrations of URD-bound Mn, Ni, Cu, Zn, As, Rb, Ba, Cr, Mg, and Al and concentrations of their water-soluble fraction were determined. The contamination characteristics and health risk related to these elements were assessed. Contamination level assessment was done by Pollution Load Index (PLI), which indicated much higher pollution of Katowice agglomeration than Wrocław. The enrichment factor values (EF) showed that the most elements in both Katowice and Wrocław orginated from anthropogenic sources. The calculations of geo-accumulation index (Igeo) showed that Zn and As are the key pollutants in Katowice; and in the Wrocław region, Cu, Zn, Cr, and Ni are. The principle component analysis (PCA) and correlation analysis provide information about the potential sources of metals. Additionally, a positive matrix factorization (PMF) was performed and four factors in PMF analysis were found and then interpreted by comparing to the source profiles. Three contamination sources were revealed: fossil fuel combustion, road traffic and industrial emissions. Although the main source of studied metals in Lower Silesia is road traffic, in Upper Silesia, domestic heating with the use of hard and brawn coal and industrial activity predominates. Human exposure to individual toxic metals through road dust was assessed for both children and adults. By calculating the average daily dose (ADD) via ingestion, inhalation, and dermal contact, it was found that ingestion and then dermal contact were the greatest exposure pathways for humans in Katowice and Wrocław. Children had greater health risks than adults. According to the health risk assessment, the overall non-carcinogenic risks in both urban areas was rather low. The only exception was As bound to urban road dust in Katowice agglomeration, which indicates risk for children when ingested. The total excess cancer risk (ECR) was also lower than the acceptable level (10−6–10−4) for both adults and children, although ECR for Katowice was closer to this limit.

“…Airborne ultrafine particulate matter (e.g., PM 2.5 and PM 1 ) can enter the alveolar region and blood circulatory system, leading to health issues and even death (Brunekreef and Holgate, 2002;Nel et al, 2006;Pickrell et al, 2009;Maher et al, 2013;Elser et al, 2016). Moreover, anthropogenic dust is an important medium for the formation of secondary pollutants and plays a significant role in the formation of haze events (Hanisch and Crowley, 2001;Li et al, 2001;Lee et al, 2002;Usher et al, 2002;Finlayson-Pitts et al, 2003;Rubasinghege and Grassian, 2009;Takeuchi et al, 2010;Wu et al, 2011;Huang et al, 2014).…”

Magnetic signatures of natural and anthropogenic sources of urban dust aerosol

Abstract. The characteristics of urban dust aerosols and the contributions of their natural and anthropogenic sources are of scientific interest as well as being of substantial sociopolitical and economic concern. Here we present a comprehensive study of dust flux, magnetic parameters, magnetic particulate morphology, and elemental compositions of atmospheric dustfall originating from natural dust sources in East Asia and local anthropogenic sources in Xi'an, China. The results reveal a significant inverse relationship between seasonal variations of dust flux and magnetic susceptibility (χ). By comparing dust flux and χ records, the relative contributions of dust from local anthropogenic sources are estimated. Analyses using scanning electron microscopy (SEM) combined with energy dispersive spectroscopy (EDS) indicate that magnetic particulate from different sources has distinct morphological and elemental characteristics. Detrital magnetic particles originating from natural sources are characterized by relatively smooth surfaces with Fe and O as the major elements and a minor contribution from Ti. The anthropogenic particles have angular, spherical, aggregate, and porous shapes with distinctive contributions from marker elements, including S, Cr, Cu, Zn, Ni, Mn, and Ca. Our results demonstrate that this multidisciplinary approach is effective in distinguishing dust particles derived from distant natural sources and local anthropogenic sources and for the quantitative assessment of contributions from the two end-members.

“…Previous studies into the MS of soils were searching for a rapid proxy technology of outlining areas exposed to increased pollution by atmospheric particulates of anthro-pogenic origin (Kapička et al 1999;Bourliva et al 2016;Liu et al 2016;Norouzi et al 2016). A number of studies have shown that magnetic monitoring is a robust technique for quantifying pollution particles produced by combustion and/or abrasion processes, toxic metals (Maher et al 2008;Matzka and Maher 1999) and ambient PM10 concentrations (Mitchell et al 2010).…”

Soil and dust magnetism in semi-urban area Truskavets, Ukraine

et al. 2020

The objective of this paper was to study pollution in the semi-urban area of Truskavets (Ukraine) using lowcost and energy-efficient magnetic measurements. Soil magnetic properties were measured near a railway station (transect) and near a road (transect and grid). To compare the magnetic properties of the soils from the urban areas, we sampled in a forest area located 2-3 km from Truskavets. Additionally, ten dust samples were taken 150 cm above the ground from the smooth surface of the tree bark. Near the Stebnyk Ring (the end of the second transect), we established a grid (20 × 20 m) and measured the soil magnetic susceptibility MS (mass-specific χ, and volume κ). There were taken 55 soil samples within the upper 0-5 cm of the topsoil. The results showed that low-frequency MS of the natural soil was within the range of 8-10 × 10-8 m 3 /kg, a low value for the Ukraine soils. The urban soils collected near the roadway and the railway had high MS values. Soil pollution was confirmed by the frequency dependence of magnetic susceptibility: χ fd = 2-3%. Our results, based on the thermomagnetic, hysteresis, isothermal (IRM), and anhysteretic remanent magnetization (ARM) measurements, suggested that magnetite is responsible for the increase in the magnetic signal of the urban soils. Natural soils normally contain a single domain (SD) grains. It has also been found that the high coercivity haematite and goethite are stable pedogenic minerals in the Truskavets natural soil. Overall, the magnetic measurements have proven to be a rapid, low cost, non-destructive and efficient technique for soil monitoring and air quality assessment.
