“…Recent XAS studies of RDS in Manchester, UK, focussed on the speciation of lead, zinc and chromium in RDS and their potential toxicity and long-term fate. Byrne et al (2017b) established relatively high concentrations of chromium in RDS. However, XANES analysis indicated chromium in RDS grains existed mainly as Cr(III), indicating limited bioavailability and toxicity under the predominant environmental conditions.…”

Purpose The proportion of people living in urbanised areas is predicted to rise to > 65% by 2050, and therefore, more humans than ever will be exposed to urban environmental pollution. Accumulation of organic and inorganic substances on street and road surfaces is a major global challenge requiring scientifically robust methods of establishing risk that inform management strategies. This aim of this contribution is to critically review the global literature on urban road–deposited sediment contamination with a specific focus on variability in sampling and analytical methods. Materials and methods In order to assess the concentration of contaminants in global road-deposited sediment (RDS), a comprehensive search of published RDS studies was completed. We review methodological approaches used in RDS studies to highlight the variability in datasets as a result of sampling technique, grain size fractionation, geochemical and mineralogical characterisation methods and establishing the influence of local geology on contaminant concentrations. We also consider emerging contaminants in RDS, and we provide a workflow diagram which promotes a standardised sampling and analysis regime that we believe can reduce data variability and promote collaboration when it comes to tackling the important issue of RDS contamination. Results and discussion Across the literature, Asia (except China) and Africa are underrepresented in RDS studies despite these continents having the largest and fastest growing populations, respectively. The removal of tetraethyl lead from gasoline produced a noticeable decrease in lead concentrations in global RDS, and platinum group element (PGE) concentrations in RDS were consistent with catalytic converter usage. Research into the impact of electric vehicles on non-exhaust emissions suggests other contaminants such as zinc may become more prominent in the future. Most RDS studies consider grain size fractions larger than > 20 μm due to sampling constraints despite RDS < 20 μm being most relevant to human health. The use of chemical extraction methods to establish contaminant geochemistry is popular; however, most extraction procedures are not relevant or specific to minerals identified in RDS through microscopic and spectroscopic investigations. Conclusions This review highlights considerable variability in sampling and analytical approach which makes it difficult to identify broad global patterns in RDS contamination. To remove this variability from future RDS research, this review suggests a workflow plan which attempts to improve the comparability between RDS studies. Such comparability is crucial in identifying more discrete RDS trends and informing future emission policy.

“…Furthermore, anthropogenic activities, such as the dumping Cr-contaminated liquids and solids wastes, are the reason for the hyperaccumulation of Cr in the environment [8][9][10][11]. The emission of Cr from the cooling towers of the industries and the dust rising from the roads and roadsides are considered to be the most important Cr sources [12,13].…”

Chromium (Cr) is one of the top seven toxic heavy metals, being ranked 21st among the abundantly found metals in the earth’s crust. A huge amount of Cr releases from various industries and Cr mines, which is accumulating in the agricultural land, is significantly reducing the crop development, growth, and yield. Chromium mediates phytotoxicity either by direct interaction with different plant parts and metabolic pathways or it generates internal stress by inducing the accumulation of reactive oxygen species (ROS). Thus, the role of Cr-induced ROS in the phytotoxicity is very important. In the current study, we reviewed the most recent publications regarding Cr-induced ROS, Cr-induced alteration in the enzymatic antioxidant system, Cr-induced lipid peroxidation and cell membrane damage, Cr-induced DNA damage and genotoxicity, Cr-induced ultrastructural changes in cell and subcellular level, and Cr-induced alterations in photosynthesis and photosynthetic apparatus. Taken together, we conclude that Cr-induced ROS and the suppression of the enzymatic antioxidant system actually mediate Cr-induced cytotoxic, genotoxic, ultrastructural, and photosynthetic changes in plants.

“…With respect to heavy metals, Basu and Schreiber (2013) found Fe hydroxides as the main As fraction according to SCE, but could show by EMPA that weathering of arsenopyrite to As-bearing hydroxides occurs via the formation of scorodite. Byrne et al (2017) found that Cr was bound in the residual fraction of urban sediments according to SCE and specified by EMPA that it is bound to Fe oxides and alumino-silicate glass. Kierczak et al (2008) successfully combined SCE and EMPA with respect to the mobility and speciation of Cr, Ni and Zn, but could not identify the mineralogical bonding of the mobile elements Cu and Pb due to low concentrations.…”

Geogenic metal contaminations in soils are intensely discussed in waste management, as the recyclability of excavated soil is regulated by limit values for pseudo-total contents in Austria. However, the use of pseudo-total contents overestimates the release of some contaminants such as metals into the environment. Sequential extraction provides an empiric tool to better assess the mobility of metals and predicts their bonding type in individual fractions, but the relation between the obtained fractions and the exact mineralogical bonding is often unclear. Electron microprobe analyses provide detailed mineralogical insights, but do not yield direct information about the mobility of elements. A combination of both methods has been used a few times in soil sciences in general, but never to Styrian soils. Thus, six geogenic contaminated Styrian soils and one compost soil were investigated by a method combination of sequential chemical extraction and electron microprobe analyses. Sequential extraction suggested that Cr in five substrates and As and Ni in one substrate each are bound in stable crystalline minerals, whereas Pb in four samples and Cu in two samples are adsorbed to iron and manganese hydroxides. Elemental mappings obtained by electron microprobe analyses confirmed sequential chemical extraction results and specified that Cu and Pb are bound to manganese (hydr)oxides, As to Fe-Cu-Sb-S compounds, Cr to spinels and Ni to olivine. In summary, the current study gives new information about the mobility and mineralogy of metals in six Styrian soils which is relevant for their possible recycling despite exceeded limit values for pseudo-total content.
