Temporal Study

The current temporal and spatial investigation was undertaken to determine the nature and concentration of heavy metals in road dust and to assess whether road dust was a possible source of metals to adjacent soils and gully pots.Three roads were selected in the Iron Cove catchment, Sydney Harbour, to investigate the influence of traffic volume on the heavy metal concentrations and accumulations rates with time. The mass of road dust increased irregularly with time since the last cleaning event and metal concentrations increased with traffic volume, but concentrations did not increase with antecedent time, possible due to variable particle size distributions. The mass of material accumulating on 1 m2 of road surface over 5 days was 72.5, 41.7, and 4.8 g for high (Parramatta Road), medium (Marion Street), and low (National Street) traffic volume roads, respectively. The source area of road surface for the test sites (200–400 m of road) may provide, over the 5-day test period, maximum loads of (g): Cr 2, Cu 7, Ni 2, Pb 29, and Zn 28 for Marion Street; Cr 0.1, Cu 0.3, Ni 0.1, Pb 2, and Zn 3 for National Street; and Cr 2, Cu 8, Ni 1, Pb 26, and Zn 18 for Parramatta Road. To provide better spatial information than the 3 samples sites used in the temporal study, road dust (n = 171) and gully pot (n = 23) samples where taken across the entire Iron Cove catchment. Mean concentrations of road dust were 6, 34, 164, 28 000, 284, 27, 487, and 523 μg/g for Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn, respectively, for all road types, and concentrations in gully pot material were 7, 20, 112, 24 000, 316, 20, 199, and 257 μg/g, respectively. A large proportion of these metals is associated with the mobile, fine fraction (<62.5 μm), and the majority (54–100%) of these elements are extracted with weak leaching agents (EDTA and 1 M hydrochloric acid). However, more information on speciation is required to determine bioavailability. SEM/EDAX analysis suggests that metals in the fine fraction may be adsorbed, whereas particulate metal and inclusion phases are common in the coarser (62.5–125 μm) material.Metal concentrations in parkland soils adjacent to the roads are highly enriched and increase with traffic volume. Concentrations decline markedly with distance from roads, but maximum values are at 30–50 m from the road edge, due to high-velocity wind generated by vehicles in proximity to the road. Metal-rich soils and gully pot deposits may be available for transport to the adjacent stormwater system.

This study is one of the first works which examined the assessment of heavy metal contamination of pavement-side soils in Algeria. It deals with the section of National Highway 3 (RN3), which crosses the wilaya of Batna. In the environment of sampling sites there is no industry or dangerous activity on the environment, the heavy metals addressed in this study are (Pb, Cu, Cr, Fe, Ni, Zn), their origin being road traffic. The objectives of this study were to: (1) Determine the concentrations of heavy metals in road dust; (2) Identify the sources of different heavy metals in soils and road dust; (3) Exploring the extent of heavy metal pollution in neighbouring soils. To this end, 33 samples were collected, including 03 road dust and 30 soil samples over different distances from 1m to 80m. The samples were analyzed by FRX. Results indicated that concentrations in road dust were higher than in soil. The distribution of heavy metal concentrations in dust is Fe>Pb>Zn>Cu>Cr>Ni, and the distribution in the ground is Fe>Pb>Cu>Zn>Cr>Ni in the direction of Biskra and in the opposite direction and decreases away from the road, while the distribution in the central solid ground is Fe> Cu>Cr>Pb>Zn>Ni. Climatic conditions such as wind, rainfall, temperature, humidity and the nature of the terrain were also significantly related to their enrichment in these roadside soils. The enrichment factor (EF) and the geo-accumulation index (Igeo) were calculated, as well as all elements with a (EF) that ranges from moderate to high to extremely contaminated, reflecting the high anthropogenic load of these metals in the study area and the results of the Igéo accumulation indices confirm the results obtained for the enrichment factor (EF). Doi: 10.28991/cej-2021-03091736 Full Text: PDF

One  of  the  actual  challenges  in  urban  environment  is  represented  by  the  road  dust  and  it control,  due  to  the  high  temporal  and  spatial  variability  of  the  sources:  soils,  traffic,  and  industrial activity  with  an  important  negative  impact  on  inhabitants.  Assessment  the  concentrations  of  heavy metals from road dust and establish correlations with urban environment characteristics, represent the aim of the current study. After field observations, were established the sampling points, the samples being collected in March 2013. Results indicate the metal concentrations in road dust were generally lower than those in soil. Based on the average concentrations, the order for dust metal concentrations was Mn>Zn>Cu>Pb>Cr>Ni>Co>Cd, establishing correlations with soil metal concentrations the order being  slightly  different  Mn>Zn>>Pb>Ni>Cr>Co>Cu>Cd.  The  spatial  distributions  of  metals  in  the road dust  reveal three  main  polluted areas, located into larger  road  crossing  of  the  city  as  Podu  Ros and Tudor Vladimirescu and in industrial area, located in southern part of the city. In opposition the northern part registered the lowest values due to the plenty of green spaces, the better state of roads etc.  Road  dust  heavy  metals  concentration  fit  under  the  limit  values  for  human  health  protection, describing  different  spatial  pattern,  in  accordance  with  heavy  metals  soil  concentrations  and  urban morphology and functionality.

The infiltration inlet facilities on the side of the road along with the sewage system have been constructed two decades ago in highly urbanized residential area in Tokyo. Possible release of heavy metals from the infiltration inlet was studied by analyzing sediment samples in different vertical depth. Seven heavy metals (Cr, Mn, Co, Ni, Cu, Zn and Pb) were measured. The heavy metal contents in sediment decreased with depth. The low content of heavy metals at the bottom sediment compared to the top indicated possible release of heavy metals from the inlet sediment. The heavy metals speciation study showed that the order of the extractability/mobility in the sediment in acid exchangeable fraction was Zn and Mn&gt;Co&gt;Ni&gt;Cu &gt;Cr and Pb. The mobility order in road dust also followed the similar pattern. In reducible fraction (metal oxide bound) Pb was the most mobile in the sediment while the other metals mobility order was not similar. In oxidizable fraction (organic and sulfide bound) the order was different for the sediment and road dusts. The residual fraction contained 18 to 83% heavy metals. The presence of heavy metals in acid exchangeable, reducible and oxidizable fractions indicated a future possibility of their release to the underlying soil and the groundwater.

A fluidized bed aerosol generator was connected to a 13-stage cascade impactor (nanoMOUDI) for the size fractionation of urban dust (<10 µm), followed by the gravimetric analysis of loaded PTFE filter samples. This method was used to characterize the PM10 (thoracic) fraction of road dust sampled from expressways, arterial roads and local roads in Toronto, Canada. The fine particle fractions (<1.8 µm) of all the studied samples accounted for 51–72% of the resuspended PM10 (by weight). Elemental analysis using ICP-MS and ICP-OES revealed an overall trend of element enrichment in the <1.8 µm fraction compared to the coarse fraction (1.8–10 µm) of the road dust. By contrast, archived house dust samples displayed the reverse trend for most elements. The lung bioaccessibility of target elements (Al, B, Ba, Co, Cr, Fe, La, Mn, Mo, Sb, Sr, Ti, V and Zn) was assessed for each road dust fraction using 0.1 M ammonium citrate (pH 4.4) to simulate intracellular fluid and Gamble solution (pH 7.2) to simulate interstitial lung fluid. The <1.8 µm fraction of local road dust displayed significantly higher bioaccessibility (p < 0.05) for Zn when using Gamble solution, and for seven out of the 14 target elements when using ammonium citrate. These results show the importance of characterizing the fine fraction of road dust.

This study was conducted between February and September, 2018 to evaluate heavy metal concentrations of road dust soils supporting arable crop production along five major roads connecting the Umuahia Metropolis to surrounding cities. Thirty soil samples from five major roads were collected during the dry and wet seasons at 10 m, 20 m and 30 m distances from road edges. The heavy metals were analyzed using tri-acid digestion. The results showed that mean concentrations of the heavy metals varied widely and had significant different between the seasons, among the five major roads and usually, decreased with increased in distance from the road. Accordingly, the study indicates that, the relative sequence of abundance followed the order: Fe > Zn ≥ Pb > Cd > Cr ≥ Cu > Co > Ni > Se ≥ As. Higher content of the heavy metals was recorded during the dry season (83.94 mg kg-1) than the wet season (74.72 mg kg-1). Among the roads, higher content of the heavy metals was recorded in Uzoakoli road (105.50 mg kg-1) while, the least was recorded in Aba road (53.37 mg kg-1). Similarly, higher contents of the heavy metals were recorded within the distance of 10 meters (94.56 mg kg-1) while, the least was recorded in 30 meters (61.73 mg kg-1) away for the roadside. Since the roadside soils in Umuahia Metropolis are being extensively cultivated for agricultural production, proper biomonitoring of activities in the urban environment should be done as often as possible to enlighten the public on dangers of heavy metal pollution.

Pm10 Emission

Scientific research studies conducted in various parts of the world confirm that PM10 concentrations in urban air depend to a great extent on the resuspension processes of the dust deposited on the road surface. The paper presents the results of the study related to the determination of the re-entrained PM10 emissions from four selected streets of Krakow (Southern Poland) together with the assessment of its impact on air quality. Examined streets are characterised by different traffic intensity (from 500 to over 20 000 vehicles per day) and individual vehicle structure. Dust material sampling and estimation of the PM10 emission were conducted according to the U.S. EPA methodology (AP 42 Fifth Edition). Two variants of sample collection were applied: from the road surface including the area at the curb (4 streets) and from the road surface alone (1 street). The estimates of resuspended road dust emission as well as the reference values derived from the U.S. EPA guidelines were used to assess the impact of this emission on the PM10 levels in the air at the location of one of the analysed streets. This assessment was conducted using the CALINE4 mathematical model. The study showed that the PM10 emissions from the re-entrained road dust can be responsible for up to 25 % in the winter and 50 % in the summer of the total PM10 concentrations in the air near the roads.

In this study, the concentrations of selected heavy metals (Al, Cd, Cr, Cu, Mn, Pb, Co, Fe, Ni, V and Zn) in roadside soil samples were determined by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) after microwave digestion. A total of sixty roadside soil samples were collected during July 2018 from seventeen sampling sites (5 km apart) from both sides along Irbid-Amman highway, Jordan. The average concentrations (±SD) of the investigated metals in the analyzed soil samples were found to be 18400 (± 11200), 6.0 (± 4.7), 132 (± 47), 49 (± 26), 695 (± 310), 96 (± 53), 78 (± 32), 31800 (± 12600), 116 (± 67), 141 (± 74) and 129 (± 112) µg/g for Al, Cd, Cr, Cu, Mn, Pb, Co, Fe, Ni, V and Zn, respectively. With exception of Mn, the enrichment factors for the investigated metals in roadside soils were found to be more than 10, indicating anthropogenic sources such as automobile traffic. In the absence of any industrial activities in the sampling sites, the high concentrations of the investigated metals suggest that automobile emissions are the major source of roadside soil pollution. The results obtained in this study showed that metal concentrations in the analyzed soil samples are strongly influenced by the wind direction and traffic density in the investigated area. The higher metal concentrations on the west side of the road were due to the easterly prevailing wind in the studied area. As expected, the concentrations of heavy metals decreased with increasing distance from the edge of the road. The results obtained in this work were compared with the literature values.
