Pollution status and human health risk assessment of potentially toxic elements and polycyclic aromatic hydrocarbons in urban street dust of Tyumen city, Russia

Abstract

This study investigated levels and sources of pollution and potential health risks associated with potentially toxic elements (PTEs) and polycyclic aromatic hydrocarbons (PAHs) in urban street dust collected from Tyumen city, a large transport centre with one of the highest motorization rates in Russia. Twenty street dust samples were collected from four grades of roads in five different land use areas.Research methods included measurements of physical and chemical properties of street dust, concentrations of 18 PTEs using inductively coupled plasma mass spectrometry, 12 PAHs using high-performance liquid chromatography, and statistical analysis of the data. Concentrations of Ni, Cr, Sb, and Mo, as well as medium and high molecular weight PAHs in urban street dust, were notably higher than in soils within the city, which indicates that transport is the main source of these elements. Concentrations of Cu, Cd, Pb, Zn, Mn, and As in street dust of Tyumen were lower compared to many large cities, while Cr, Ni, and Co were higher. Concentrations of PAH were comparable to other large nonindustrial cities. Total contamination of street dust by both PTEs and PAHs showed more robust relationships with the number of roadway lanes rather than land use. The estimated carcinogenic risks were low in 70% of samples and medium in 30% of samples. Noncarcinogenic risks were attributed to exposure to Co, Ni, V, and As. The total noncarcinogenic risk for adults was found to be negligible, while the risk was found to be moderate for children.

Geochemistry of street dust in Tyumen, Russia: influence of traffic load

“…The objectives of the presented work are to identify the features of HMM accumulation in road dust, depending on the tra c intensity and the location of other polluting objects, to assess the ratio of natural and anthropogenic sources, to evaluate the level of pollution. The present study complements and expands the work of Konstantinova et al (2020) by: (a) collecting a large number of samples from a wider area around the city of Tyumen (50 sampling sites); (b) measuring the concentrations of other major and trace elements (Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sc, Sr, Ti, U, V and Zn) in the road dust; (c) estimates of the ratio of natural and anthropogenic sources of HMMs in road dust.…”

“…According to the classi cation of Hakanson (1980), in terms of Cf, the content of Co, Cu, Zn, As, Mo, Ag, Cd, Sn, W, Pb Bi corresponds to the level of "moderate contamination", Cr -"signi cant contamination" and Ni, Sb -"very high contamination". The pollution of road dust in Tyumen with chromium and nickel was previously noted by Konstantinova et al (2020), who revealed that the concentration of these elements is 4 and 7 times higher, respectively, compared to urban soils. An increased content of Cr, Ni, Pb, V was also noted in the snow cover (Guseinov et al 1997), which con rms the atmospheric input of these metals.…”

“…The composition of road dust was determined in Moscow (Ladonin, Plyaskina 2009;Vlasov 2015;Kasimov et al 2019b), cities of the Perm region (Kaigorodov et al 2009); Chelyabinsk (Krupnova et al 2020), Alushta (Kasimov et al 2019a). In Tyumen, 20 samples of road dust were analyzed, as a result of which a conclusion was made about the high content of Cr, Ni, and Co (Konstantinova et al 2020).…”

Daily Variations In Wet Deposition And Washout Rates Of Potentially Toxic Elements In Moscow During Spring Season

“…This indicates the significant role of wet deposition processes for the PTEs input into terrestrial landscapes. The main sources of most of these PTEs are vehicle emissions, fuel combustion, tires and brake pads wear, road surface abrasion, roadside soil particles blowing, industrial enterprises emissions, as well as macroregional long-distance transport of pollutants (Demetriades and Birke 2015;Grigoratos and Martini 2015;Grivas et al 2018;Konstantinova et al 2020;Liyandeniya et al 2020;Logiewa et al 2020;Orlović-Leko et al 2020;Ramírez et al 2020;Seleznev et al 2020;Tian et al 2020), which is confirmed by the previously identified sources of snow cover pollution in the western part of Moscow (Vlasov et al 2020). The remaining PTEs on the territory of the MO MSU were apparently of mixed anthropogenic-terrigenous sources (P 38 , Ba 31 , As 30 , W 22 , Mn 20 , Sn 19 , Na 16 , Co 14 , Ni 12 , Be 11 , K 11 ) and terrigenous origin (Rb 6 , Cr 4 , Fe 3 ), which indicates the influence of solid particles blown out from the Earth's surface and included in the atmospheric precipitation.…”

Dissolved and Suspended Forms of Metals and Metalloids in Snow Cover of Megacity: Partitioning and Deposition Rates in Western Moscow

“…Input of a large group of MMs as a result of blowing and splashing mud material from the surface of roads is indicated by the formation of associations of suspended Ni-Al-Mg-Ti-Ca-Sr-Mn-Co-W-K-Rb-Ba-Ni-Fe-V and dissolved Ti-Fe-Pb-Al-Sn-Bi-W. Thus, Al, Ti, Fe, Mn, Rb, and K come predominantly with soil particles upon blowing [118][119][120]; Na, Ca, Mg, and Sr-with construction dust and large DISs particles; W, Sn, Bi, Co, Ni, Ba, Pb, and Ti-with various size fractions of road dust [67,95,119,[121][122][123][124][125].…”
