“…Most of these studies focused mainly on six to eight metals [3][4][5][6][7][8][9][10][11][12]. Some studies extended the list to more than eight metals [13][14][15][16][17]. The results showed that the concentration of metals fluctuates widely up to 8430 mg/kg [6].…”

“…From the literature review, it was found that most studies focused on common metals (Cd, Co, Ni, Pb, Cr, Cu, Mn, and Zn). Recently, survey studies have been undertaken in cities with high traffic density and industrial development areas, such as Ho Chi Minh City [13,14]. The results showed that in addition to the metals mentioned above, many other metals were detected (Se, Sb, Mo, B, Sn, As, V, Ti, etc.)…”

The present study focused on investigating the contamination and risk assessment for 16 metals in street dust from Ha Noi highway, Ho Chi Minh City. The results indicated that the concentrations of metals (mg/kg) were found, in decreasing order, to be Ti (676.3 ± 155.4) > Zn (519.2 ± 318.9) > Mn (426.6 ±113.1) > Cu (144.7 ± 61.5) > Cr (81.4 ± 22.6) > Pb (52.2 ± 22.9) > V (35.5 ± 5.6) > Ni (30.9 ± 9.5) > Co (8.3 ± 1.2) > As (8.3 ± 2.5) > Sn (7.0 ± 3.6) > B (5.7 ± 0.9) > Mo (4.1 ± 1.7) > Sb (0.8 ± 0.3) > Cd (0.6 ± 0.2) > Se (0.4 ± 0.1). The geo-accumulation index (Igeo) showed moderate contamination levels for Pb, Cd, Cu, Sn, Mo, and Zn. The enrichment factor (EF) values revealed moderate levels for Cd, Cu, Mo, and Sn but moderate–severe levels for Zn. The pollution load index of the heavy metals was moderate. The potential ecological risk (207.43) showed a high potential. Notably, 40.7% and 33.5% of the ecological risks were contributed by Zn and Mn, respectively. These findings are expected to provide useful information to decision-makers about environmental quality control strategies.

“…They concluded that particles were most contaminated in the central part of the city due to the large number of cars and traffic congestions. Zhang et al [20] analyzed a total of 64 dust samples collected from five urban roads and four parks in Tianjin, China to determine the size distribution and elemental composition of the PM 10 fraction. The researchers found that crustal elements accounted for 30.14% of the PM 10 fractions and the most abundant trace elements were Zn, Mn, and Cu (range, 277 to 874 mg/kg).…”

Spatial Distribution and Chemical Composition of Road Dust in Two High-Altitude Latin American Cities

et al. 2021

Road dust (RD) resuspension is one of the main sources of particulate matter in cities with adverse impacts on air quality, health, and climate. Studies on the variability of the deposited PM10 fraction of RD (RD10) have been limited in Latin America, whereby our understanding of the central factors that control this pollutant remains incomplete. In this study, forty-one RD10 samples were collected in two Andean cities (Bogotá and Manizales) and analyzed for ions, minerals, and trace elements. RD10 levels varied between 1.8–45.7 mg/m2, with an average of 11.8 mg/m2, in Bogotá and between 0.8–26.7 mg/m2, with an average of 5.7 mg/m2, in Manizales. Minerals were the most abundant species in both cities, with a fraction significantly larger in Manizales (38%) than Bogotá (9%). The difference could be explained mainly by the complex topography and the composition of soil derived from volcanic ash in Manizales. The volcanic activity was also associated with SO4⁻2 and Clˉ. Enrichment factors and principal component analysis were conducted to explore potential factors associated to sources of RD10. Elements such as Cu, Pb, Cr, Ni, V, Sb, and Mo were mainly associated with exhaust and non-exhaust traffic emissions.

“…Furthermore, pollution created by personal vehicular movements by tourists to view the lush green landscape in these locations may have an adverse effect on soil. Heavy metal pollutions on roadside soils and road dust due to vehicular movement are broadly studied and documented in several pieces of the literature (Khan et al 2011;Yan et al 2018;Zhang et al 2019 and references therein). However, traffic-induced soil chemical changes on roadside soils of tea growing regions are very limited and even not available.…”
