“…Similar observations were recorded by other studies [27,86]. Children are the most exposed health risk group as ADD via oral and inhalation route is about two times higher in children than adults, while the opposite trend was observed when analyzing the dermal route, in this case adults are the most endangered group [27,86].…”

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.

“…This may result in higher mobility of the metals and their bioaccumulation by plants, especially in acidic soils, which are also present in the studied areas of E261 expressway. The study of Świetlik et al (2015) [10] showed that lead content in barrier dusts sampled from the noise barriers along E77 expressway in Poland ranged from 33.2 to 57.3 mg kg -1 , depending on the sampling point and sampling height. These values are higher compared to our results (11.873-38.193 mg kg -1 ).…”

“…Thus, it could be expected that road dusts deposited on the noise barriers, may be good indicators of metal pollution and density of road traffic. However, there is a limit-ed number of studies investigating heavy metal contents in barrier dusts sampled from the noise barriers [10]. The aim of this study was to determine total cadmium and lead contents in barrier dusts sampled from three noise barriers located along expressway E261 in Poland.…”

“…However, it is important issue for the health of people living or working in such areas. Although there are many studies about road pollution dispersion around noise barrier [BALDAUF et al 2016;ŚWIETLIK et al 2015;TRUJILLO-GONZÁLEZ et al 2016] the influence of road and sound walls configuration has not been fully investigated [JEONG 2015].…”

Dense road network change the landscape as well as in many different ways affect the environment and living organisms. The works on reducing the exposures to traffic pollutants carried out all around the world. In the last decade, noise barriers in large numbers began to appear along the main streets and became a common feature of urban architecture in Poland. Besides being barriers to the spread of the noise on the neighboring areas these constructions might also contribute to reducing the spread of air pollution, especially road dust particles with associated trace metals (Cd, Cu, Mn, Ni, Pb, Zn).The aim of the study described in the article was to examine if the extent to which "green walls" noise barriers and transparent acrylic-glass noise barriers located along roads can contribute to a change in the spread of trace elements from the road traffic to outside of the road area. Toxic metals which occur in road dust in significant concentrations (Cu, Fe, Mn, Pb and Zn) were selected and their concentrations in soil samples were examined. The samples were collected at close vicinity of the road edge in an open area as well as in an area with noise barriers.
