“…Most exceptions were observed for Zn found in high concentrations in all catchments, indicating weak correlations with TSS during rain in the two catchments without baseflow (A and C). This might be explained partly by the variety of Zn sources in these two catchments including building facades, roofing materials and traffic (Mosley and Peake, 2001; Sörme et al, 2001; Petrucci et al, 2014), contributing to high concentrations of dissolved Zn, especially in catchment C.…”

“…Trace metals (TMs) in stormwater and snowmelt originate from traffic (Kayhanian et al, 2012; Huber et al, 2016), wash-off or corrosion of buildings and structures (Sörme et al, 2001; Petrucci et al, 2014; Huber et al, 2016), atmospheric deposition (Gunawardena et al, 2013), crustal leaching (Joshi and Balasubramanian, 2010) and impurities in deicers and grit applied to roads in winter maintenance (Westerlund et al, 2003). Thus, while most of the TM burden is associated with anthropogenic activities, small contributions from mineral sources should be acknowledged as well, particularly in the case of Pb, Ni, Cu and Cr in peat soils (Cory et al, 2006; Lidman et al, 2014).…”

Inorganic chemicals in urban stormwater and snowmelt runoff originate from catchment geology and anthropogenic activities. The occurrence, partitioning and mobility of six minerals and six trace metal (TM) indicators of anthropogenic activities were studied in stormwater, snowmelt and baseflow in four urban catchments, and the sampling of inorganics was supplemented by measurements of electrical conductivity (EC), pH and total suspended solids (TSSs). Minerals occurred at concentrations several orders of magnitude higher (1–102 mg/L) than those of TMs (10−2–102 μg/L) and reflected the composition of local groundwater seeping into sewers. Concentrations of Ca, K, Mg and Na were enhanced by baseflow contributions and followed closely the electrical conductivity. Al and Fe minerals occurred in insoluble forms, and their pollutographs were similar to those of TMs, whose concentrations mimicked, to some extent, the flux of TSS. The TMs with the highest and lowest particulate fractions were Cr&Pb and Cu&Zn, respectively. The concentrations of total TMs in snowmelt were two to four times higher than those in stormwater, and both sources likely exceeded some of the stormwater effluent limits (for Cd, Cu and Zn) proposed in Sweden. Where such concentrations depended on water hardness, the risk of toxicity might be reduced by elevated hardness of the monitored snowmelt and stormwater. Recognizing the good ecological status of the study area receiving water, Lake Storsjön, some protection against polluted runoff and snowmelt may be needed and could be achieved by implementing stormwater management measures controlling TSS and TMs.

“…Ni is mostly emitted during fossil fuels combustion [28] and also can be released from brakes and tire wear. [29] Cu and Zn could be the coproducts in brake process.

To characterize the elemental composition and source apportionment of aerosols in roadside area, particulate matters with aerodynamic diameter less than 2.5 μm (PM 2.5 ) were collected in close proximity to a road from September 2017 to February 2018 in downtown Chengdu, China. An energy-dispersive X-ray fluorescence spectrometer was used to quantify elemental constituents (Al, Si, S, K, Mn, Fe, Ni, Cu, Zn, As, and Pb) of PM 2.5 and was calibrated by inhouse standards instead of commercial standards. The constructed calibration curves exhibited good linearity with all correlation coefficients greater than 0.98. The proposed calibration method proved to be reliable for the subsequent elemental analyses due to the satisfactory performance of u-score and precision that were validated by the certified reference materials (#2783). The results revealed that average PM 2.5 concentrations of 92.2 ± 45.6 and 113.2 ± 60.3 μg/m 3 were respectively observed in autumn and in winter. The major trace elements identified were K, S, and Fe and the minor contributions were from Cu and As. Most crustal elements showed decline in winter except for K, and most anthropogenic elements showed increase in winter except for Ni. Using rotation factor analysis and cluster analysis based on the elemental dataset, four potential sources were identified: road dust, vehicular emissions, coal and biomass burning, and industrial emissions. This research will provide a better understanding of traffic-related PM 2.5 composition, and this can be used in the mitigation and prevention programs.

The air PM 2.5 concentration and its heavy metal content (Fe, Pb, Mn, Ni, As) were measured in the Metropolitan Area of Monterrey, Méxicoin Mexico, an area that is characterized by both very active and diverse industrial activity and intense highway traffic and industrial activity. The 24-h PM 2.5 samples were collected in two different zones during a 1-year-long measurement program (February 2008-February 2009). The year PM 2.5 average was above 15 µg/m 3 exceeding Mexican and international standards. The difference of PM 2.5 in each zone was not statistically significant. The greatest metal content was for iron, followed by lead, manganese, nickel and arsenic. The difference in metal content for Pb, Mn, and As was statistically significant.
