“…This was also evidenced by the report of a significant relationship between ADT and concentrations of various pollutants present in road environments [1,2]. Urban pollutants were constantly emitted and transported within air masses and tended to accumulate in road-deposited sediment (RDS) [3]. The RDS originated from the accumulation of particles from natural (e.g., soil drag) and anthropogenic sources (e.g., vehicular traffic, industries, and construction), which generated a heterogeneous and complex mixture of pollutants due to their various emission sources [4][5][6].…”

Population growth has led to the intensification of average daily traffic (ADT), highlighting vehicles as one of the major sources of heavy metal (HM) pollution in cities. The objective of this paper is to conduct a spatial analysis of the HM pollution associated with road-deposited sediments (RDSs), based on the ADT observed in the main roads of a Latin American megacity (Bogotá, Colombia). The following risk indices were considered: Geoaccumulation Index (Igeo), Integrated Pollution Index (IPI), Ecological Risk Index (ERI), Comprehensive Potential Ecological Risk Index (CERI), Hazard Index (HI), and Carcinogenic Risk Index (CRI). The findings confirm that a size fraction < 250 μm is the most suitable for studying the risk of HMs in the RDS from the indices considered. The best HMs indicative of the relationship with ADT are Ni, Cu, and Pb. The Pb is the HM of most attention, and Cr gains positions for its toxicity level during the evaluation of ecological, non-carcinogenic, and carcinogenic risks, respectively. Finally, the linear regression models developed between ADT and each of the risk indices considered have a better fit (R2 > 0.910) compared to the linear regression models developed between ADT and HM concentrations (R2 > 0.322).

“…Urban road dust, which consists of a complex mixture of particles from various sources, poses a significant threat to both the environment and human health. Despite growing concern surrounding road dust pollution, there remains a dearth of scientific investigations focused specifically on the elemental composition of road dust at petrol stations (Rybak et al 2022). To date, there have been no studies on hazardous elements in road dust collected from petrol stations.…”

Samples of road dust from petrol stations (n= 20) located in Rzeszów (Podkarpackie, Poland) were analyzed for the finding of potential markers of traffic-related pollution. Level (μg/g) of Mo, U, As, Hg, Th, Pb, Ni, Cu, Cr, Be, Sr, Zr, Zn, Mn, and Fe was measured using field portable X-ray spectroscopy (FP-XRF) as ‘white analytical technique’. Our research demonstrated for the first time the utility of using PF-XRF for environmental toxicological assessment of road dust at petrol stations. The qualitative and quantitative composition of the tested dust samples provides valuable research material for creating and updating regulations and finding pollution hotspots such as petrol stations. It was possible to find potential markers of traffic-related pollution (e.g., Zr and Fe form of disk brakes or brake pads). Certain elements of the study give ambiguous signals related to fuel distribution and road traffic. They can come from various sources of environmental contamination. The adoption of evidence-based policies to minimize pollution, conserve the environment, and protect the well-being of people living or working near gas stations is anticipated to be aided by these findings for policymakers, regulatory authorities, and stakeholders. The assessment of elemental health risk involved the computation of doses for both carcinogenic and non-carcinogenic metals, as well as the calculation of lifetime average daily doses, or LADD.

“…In addition, children pose a considerable non-carcinogenic health risk to their bodies through the inhalation of indoor dust in Ahvaz. Overall, HMs in the USD of oasis cities are significantly harmful to urban ecology and human health [ 68 , 69 ]. Therefore, in this study, a typical oasis city (Changji city) was selected as the study area, and the enrichment status, spatial distribution, pollution level, health risk, and sources of HMs in USD were quantitatively analyzed in order to provide data support for monitoring ecological safety and human health in oasis cities in arid regions.…”

High concentrations of heavy metals (HMs) in urban surface dust (USD) can be extremely hazardous to urban ecology and human health. Oasis cities are located at the edge of deserts and are more exposed to salt/sandstorms, and they face a significantly higher accumulation of USD than wet or semi-humid areas. However, systematic studies on the pollution and risk assessment of HMs in USD in oasis cities have rarely been conducted. This study systematically analyzed the enrichment status, spatial distribution, pollution levels, health risks, and sources of HMs in USD in a typical oasis city (Changji city). The results showed that the average concentrations of Pb, Ni, As, Cd, Hg, and Cu in the USD of Changji city were 46.83, 26.35, 9.92, 0.21, 0.047, and 59.33 mg/kg, respectively, and the results of the pollution index evaluation showed moderate Pb, Hg, and Cu pollution, mild Cd pollution, and no Ni or As pollution. The spatial distribution of HM concentrations in the USD was substantially heterogeneous. High values of Pb, Hg, and Cu concentrations were mainly observed in areas with relatively intensive transportation and commercial activities, and high values of Cd and Ni were observed in industrial areas. The health risk assessment showed that HMs do not pose non-carcinogenic risks to humans at their current level, but they pose a carcinogenic risk to children, with As contributing the largest carcinogenic and non-carcinogenic risks. The source identification of HMs showed that the main pollution of HMs were traffic sources for Pb and Cu, industrial sources for Ni and Cd, natural sources for As, and coal-fired sources for Hg. According to the results of the quantitative analysis with the positive matrix factorization, the contribution of pollution sources followed this order: industrial sources (31.08%) > traffic sources (26.80%) > coal-fired sources (23.31%) > natural sources (18.81%).
