“…Blecken et al 2009b;Davis et al 2001;Muthanna et al 2007a). Thus, the high metal removal in the top layer indicates that the biofilters in the study at hand produced reliable results and that the metals do not ingress deeply into the filter, e.g.…”

“…It is relatively difficult to compare the metal concentrations measured in plants from different studies since the concentrations might differ significantly due to the applied metal load, the varying metal uptake capacity of different plant species and the climatic conditions (Sun and Davis 2007;Muthanna et al 2007a).…”

“…Generally, it is assumed that only a smaller part of the metal burden removed by the biofilter ends up in plants; Davis et al (2001), Muthanna et al (2007a) and Sun and Davis (2007) calculated this fraction as 5% to 10%. Thus, the role of the plants in metal treatment should not be overestimated.…”

Stormwater biofilters, which are recommended for application in both Water-Sensitive Urban Design and Low Impact Development, can remove up to 80% or 90% of total metals found in stormwater. However, their winter operation is a common concern. That was addressed in this study by investigating the metal removal effectiveness of replicate laboratory biofilter mesocosms at 2°C, 8°C and 20°C. As recommended for cold climate bioretention, coarse filter media were implemented and in the top 100 mm layer topsoil was added to increase the sorption capacity. Cd, Cu, Pb and Zn concentrations measured in the biofilter effluent were far below those in the influent and this significantly improved the treated stormwater quality. Contrary to a common notion that coarse media in the main filter body impair dissolved metal sorption, satisfactory removals of dissolved metals were found in this study with most metal burdens retained in the top layer of the filter in which the sorption capacity was enhanced by topsoil. Some metal uptake by the plants was also detected. Temperature did not affect Cd, Pb and Zn removals in general, but Cu removals increased with decreasing temperatures. This was explained by increased biological activities in the filters at warmer temperatures, which may have led to an increased release of Cu with dissolved organic matter originating from root turnover and decomposition of organic litter and debris. Furthermore, plant uptake and biofilm adsorption may also be influenced by temperature. However, even in the worst case (i.e. at 20°C), Cu was removed effectively from the stormwater. Further research needs were identified including the effects of road salts on stormwater biofiltration during the winter period.

“…Snowmelt is a main driver for increased levels of polycyclic aromatic hydrocarbons, salinity, and metals (e.g., cadmium, copper, lead, mercury, and zinc) in river and lake water in the spring compared with the rest of the year (Pham et al 1993;Westerlund and Viklander 2006;Muthanna et al 2007;Novotny et al 2008). By proper handling and management of snow, snowmelt runoff pathways can be controlled and pollution of surface water bodies prevented (Reinosdotter and Viklander 2005).…”

Cities are under pressure to operate their services effectively and project costs of operations across various timeframes. In high-latitude and high-altitude urban centers, snow management is one of the larger unknowns and has both operational and budgetary limitations. Snowfall and snow depth observations within urban environments are important to plan snow clearing and prepare for the effects of spring runoff on cities' drainage systems. In-house research functions are expensive, but one way to overcome that expense and still produce effective data is through citizen science. In this paper, we examine the potential to use citizen science for snowfall data collection in urban environments. A group of volunteers measured daily snowfall and snow depth at an urban site in Saskatoon (Canada) during two winters. Reliability was assessed with a statistical consistency analysis and a comparison with other data sets collected around Saskatoon. We found that citizen-sciencederived data were more reliable and relevant for many urban management stakeholders. Feedback from the participants demonstrated reflexivity about social learning and a renewed sense of community built around generating reliable and useful data. We conclude that citizen science holds great potential to improve data provision for effective and sustainable city planning and greater social learning benefits overall.

“…free ion and labile complexes are more toxic and bioavailable to aqueous organisms and plants [18][19][20][21]. The information on speciation of heavy metals is useful because removals of heavy metals in runoff by plant uptake are sometimes expected [22]. Besides, transport of heavy metals is also related to their speciation.…”
