“…In particular, the concentrations of Cr, Cu, Hg, Pb, and Zn in street dust were generally higher than that in soils. Cr, Cu, Hg, Pb, and Zn in street dust must be affected by other factors [55,56]. Even more noticeable was the fact that the Hg content in street dust was greater than that in soils almost everywhere.…”

“…The methods that were used in this study are generally applicable to assess any railway’s scope of influence [77,83,93] on heavy metals in street dust at any coal transportation hub. It should be noted, however, that restricting such analyses to the areas immediately around railway lines is insufficient to address the problem of heavy-metal contamination, because contamination is also attributable to other industries and to the population living near the hub [55,56]. These sources of heavy metals should also be identified and addressed.…”

Coal is a vital basic energy source in China, and rail serving is its major mode of transportation. Heavy metals in street dust surrounding the coal railway do harm to the environment and pose a potential risk to human health. This paper aims to identify the effects of coal transportation hubs on heavy metals in street dust. The geoaccumulation index and ecological risk index were used to assess the contamination levels of the following elements in Yuanping, Shanxi: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn). The levels of contamination of these heavy metals in soils were compared to those in street dust, and the difference between the railway’s and mining’s impacts on dust’s heavy-metal concentrations was explored. The results indicated that Cr and Pb in street dust were mainly affected by coal railway transportation, and the interaction effect of coal railway transportation and mining was greater than either of them alone. A potential control and prevention zone for Cr and Pb extending 1 km to both sides of the railway was identified. This work proves that coal railway transportation has certain effect on heavy metals in street dust and provides a scientific approach for future environmental impact assessments of coal transportation via railway.

“…In this study, experiments were done on a total of 58 samples, followed by evaluation through multiple statistical methods and geographic information system (GIS). The results indicated that levels of pollutants increased according to increased urban traffic and density, such that the city center with the largest traffic load had higher levels of pollutants (44). A study on Hangzhou city in China by XU et al investigated the chemical characteristics of dust fall determined values for chromium, manganese, nickel, lead, zinc, cobalt, aluminum, iron, potassium, sodium, calcium and magnesium elements.…”

Background: The phenomenon of dust is a serious environmental problem in dry and semi dry regions. It has a destructive effect for the residents of such regions. Over two-thirds of Iran is in areas of dry and semi-dry climate conditions. Methods: In this research, dust fall measurements were taken in 41 stations across Yazd city using a marble dust collector (MDCO) located in different parts of the city. Next, the chemical characteristics of dust were determined using the XRF method. Finally, levels of dust fall across the 4 seasons of the year and status of the constituent elements of dust were determined through ArcGIS software and the Kriging technique. The Raster calculator function was used to make determinations of the effects of dust fall at each of the stations over the course of the year. Remote sensing system, along with maps taken from Landsat and the band combination technique were processed using ENVI software to extract vegetation density and building density maps of the studied region. Results: Results showed that spring had the highest level of dust fall with a value of 200 g/cm 2 . In total, in 109 km 2 of the studied region had average dust fall of 110 g/m 2 that contributed to 12 057 tons of dust over Yazd city in 2015. The constituent elements of the dust fall according to decreasing amounts were as follows: Si>Ca>Al>C>Mg>Fe>K>Na>S>Ti>Cl>P>Mn>Sr>Zn. Conclusion: These results indicate accuracy of the Kriging technique for application in dust zoning. The factors of vegetation and green space were determined as effective on adsorbing dust. Increased building density and height of buildings also contributed to development of dust fall.
