“…The latest studies report that metal contamination of railway urbanozems is not limited to "classical" anthropogenic HM (Pb, Zn, Cu, Cr, Cd). Thus, the authors (Stancic et al, 2022) showed that in soils along railways pronounced enrichment of Sb and Sn is found, it is 87 and 33 times higher than the median value for European soils, respectively.…”

Urbanozems with typical pollution are formed along railways: heavy metals (HM), oil products, anthropogenic organic matter. Depending on the natural zone and intensity of the leaching regime, the accumulated pollution can have a different effect on the integral environmental indicators of soils – the toxicity and enzymatic activity. The aim of the work was to determine the influence of the railway on the physicochemical characteristics of adjacent urbanozems that are formed in the southern taiga zone and to find out the interrelation of these indicators with the toxicity and catalase activity of the soil. Samples of urbanozems were taken from the surface layer of 0-10 cm at the distance of 50 m west and east of the railway and at the distance of 100, 500, 1000 m of it (east). The pH, content of organic matter, humus, ammonium nitrogen, mobile forms of HM, mortality for Daphnia magna Straus, influence on bioluminescence of Escherichia coli Migula, and the catalase activity were determined in the samples. It was shown that the levels of toxicity and the activity of catalase are strongly related to the distance from the railway: Pearson’s coefficients (r) were -0.53 (D. magna), -0.69 (E. coli), 0.95 (catalase). However, the interrelation between the total pollution index (TPI) of metals and integral indicators is lower: r=0.50 for the pair “D. magna – TPI”, r=0.42 for “E. coli – TPI”, r=0.19 for “catalase – TPI”. Consequently, the reactions of living organisms and the activity of catalase were formed in response to a combination of pollutants, not to one group of compounds.

“…Traffic in the Varaždin area includes road and rail traffic. Areas near railway stations, especially railway intersections with high traffic frequency, are known as places with high soil pollution with HMs [ 53 , 54 , 72 , 73 ]. However, these areas are very limited.…”

The main objective of this study was to investigate whether the most common wild plant species of urban grassland can be used for phytoremediation of soils polluted with heavy metals. The study was conducted in the city of Varaždin, in northern Croatia. The content of heavy metals (Cd, Cu, Fe, Mn, Ni, Pb, Zn) was determined in soil samples as well as in unwashed and washed plant samples (Taraxacum officinale, Plantago lanceolata, Trifolium repens). The results show that the most polluted site is the railway station, while most sites are polluted by road traffic. The soils are most enriched with Pb, Cu, Zn and Cd. The bioconcentration factors for all three plant species are <1, indicating the relatively low capacity of phytoextraction. A considerable amount of heavy metals is found in the dust deposited on the plant surface, which is confirmed by a statistically significant difference between washed and unwashed plant samples. In addition, the biomass of each plant species that can be removed (in t/ha year), the mass of specific heavy metal that can be removed (in kg/ha), and the years required for phytoremediation are reported. In conclusion, phytoremediation with only common plant species of urban grassland is not possible within a reasonable period of time.

“…Here, Sn does not show a correlation with Fe and Mn (Figure S3f in Supporting Information S1), and the highest concentrations are located along the main roads and railways. Indeed, a recent work by Stančić et al (2022) indicated railway-originated dust as a potential source of Sn in nearby soil.…”

This study examines the accumulation, distribution, and mobility of Potentially Toxic Elements (PTEs) in the sediments of a low‐lying coastal drainage network (Ravenna, Italy). The aim is to understand the geochemical processes occurring between drainage water and canal bed sediments and assess factors affecting and driving PTE distribution and enrichment in these environments. A geochemical database resulting from the analysis of 203 drainage sediment samples was analyzed using Principal Component Analysis and compared to undisturbed near‐surface sediment samples from the same depth and depositional environment. The results reveal PTEs exceeding national regulation limits. Distance from the sea, electrical conductivity of drainage water, and fertilizer use were identified as the main driving factors. The primary mechanisms for PTE precipitation (As, Co, Mo) and subsequent enrichment in the sediments is attributed to the absorption on Fe‐ and Mn‐oxyhydroxides (HFO and HMO), particularly in high salinity areas near the coast. While Cu, Zn, Pb, Cr, and V also have affinity for HFO and HMO, their adsorption efficiency decreases due to the competition with salt‐derived cations during ongoing salinization processes. Anthropogenic sources, including agriculture, hunting activities, traffic dust, and railways, contribute to the local abundance of other elements (Cr, Ni, Cu, Zn, Pb, and Sn). This paper's significant progress lies in assessing the concurrent interactions of chemical and physical processes that drive PTE distribution and accumulation in reclaimed low‐lying coastal plains. The findings are significant for assessing PTE accumulation risks and sediment toxicity in coastal areas affected by water salinization, drainage, and subsidence, providing valuable information to water management institutions globally.
