“…Landscape characteristics of the catchment such as geology, slope, drainage and land use are important factors controlling the forms and quantities of sediments and metals that are transported to rivers (Miller et al, 2003;Kang et al, 2009). The transport mechanisms vary for each metal, depending on its abundance, solubility or distribution in particle size, among other factors (Horowitz et al, 1990;Park et al, 2007;Pokrovsky et al, 2010).…”

“…However, rural catchment studies focusing on factors affecting metal loads during rainfall-runoff events are limited and most studies have not taken into account both hydrological and meteorological parameters, even though these are important for metal exportation. For instance, Miller et al (2003) associated high metal loads with high discharge in two agricultural catchments, while Kang et al (2009) associated said loads with an increase in both rainfall during the events and antecedent rainfall in the inlet and the outlet of an urban catchment.…”

Abstract. This paper examines sediment and metal (Al, Fe, Mn, Cu, and Zn) exportation at different timescales (annual, seasonal and event) during a 3-year period (2005)(2006)(2007)(2008) in the Mero River headwater, a rural catchment under humid temperate climate. Interannual differences were found both in annual loads and their distributions throughout the year. At annual scale, sediment and particulate metal loads followed the same trend as streamflow, while dissolved metals showed different patterns. Runoff events contributed to 63 % of the total sediment load, whereas particulate and dissolved loads in events accounted for between 38-61 and 27-49 %, respectively. Runoff events were characterized by high variability in sediment and metal loads, a few events representing a high percentage of the metal exported. Sediment loads were related to maximum and initial discharge. Particulate metal loads were highly correlated with sediment loads, runoff being the hydrological variable that best explains the load of these metals. Dissolved metal loads displayed different patterns. Dissolved Al, showed a great correlation with runoff, while dissolved Mn with maximum discharge.

“…The most common contaminants, other than sediment, reported in surface and shallow ground waters are metals (see Kang et al, 2009;Kang et al, 2010;Naito et al, 2010;Plauborg et al, 2010;Zgheib et al, 2012). The USA nationwide urban runoff programme found as early as 1983 that heavy metals (including copper, zinc and lead) were the most prevalent priority pollutants in urban runoff within the country; with some metals present often enough, and in signficant enough concentrations, to potentially threaten beneficial uses (USEPA, 1983).…”

Presented in this paper are the results of correlational analyses and logistic regression between metal substances (Cd, Cu, Pb, Zn), as well as suspended solids removal, and physical pond parameters of 19 stormwater retention pond case studies obtained from the International Stormwater BMP database. Included are cross-correlations between metals and solids in pond influent, effluent and removals. The findings provide insights fundamental to further development of improved models and design guidelines for stormwater ponds. Indications were that (i) pond efficiencies differed between high and low influent concentrations and masses, (ii) concentration was an invalid indicator of correlations between substances in pond influent and effluent as well as the fractions of substances removed within ponds, (iii) total cadmium, copper, lead, zinc and total suspended solids (TSS) were associated in surface runoff and similarly removed within ponds, (iv) statistically significant correlations were often only found in data groups either above or below a specific statistic (quartile value, median) for specific pond parameters, indicating that removals may have been differently influenced by pond parameters over different data ranges, and (v) the volume within the permanent pool was of greater importance to pond efficiencies than the volume captured during storm events.

For example, Kang et al (2009) have recently reported that in Gwangju City, Korea, wet weather flow is the primary contributor to the loads of many heavy metals, accounting for 44-93% of the total annual dissolved metal loads depending on the metal species.…”

The loads and sources of heavy metals (Cd, Co, Cu, Mn, Mo, Ni, Pb, V, and Zn) in the midstream of Tama River were evaluated on the basis of their chemical analyses in ordinary and stormwater runoff from July 2007 to November 2008. Tama River is one of the three major rivers flowing into Tokyo Bay. The total annual water discharges differed largely for 2007 and 2008, depending on the scales of typhoon rainfalls and other heavy rainfalls in each year. The concentrations of the metals other than Mo in the river did not change markedly at a flow rate of less than approximately 200 m 3 s −1 , but at higher flow rates, the concentrations of all the metals increased linearly with the increase in the log of flow rate (r 2 =0.94-0.99). The annual loads of heavy metals for 2007 and 2008 were estimated using regression equations between the above parameters and the hourly flow rate data for each year. For the metals other than Mo, the contribution of the loads at higher flow rates (>200 m 3 s −1 ) was much larger than that at lower flow rates (<200 m 3 s −1 ), showing the importance of the particulate loads (primarily crustal materials) during storm runoff following typhoon rainfalls and other heavy rainfalls. In contrast, the loads of Mo at lower flow rates accounted for major portions (56-78%) of the total loads, because of a relatively small contribution of particulate load during storm runoff. The contribution of the loads of Mo, Zn, Cd, Cu, and Ni at lower flow rates to the annual loads was larger than that of other metals. It was found that the concentrations of these metals in ordinary runoff are strongly affected by the discharge of treated water from sewage treatment plants which are located along the catchment. Thus, treated water from sewage treatment plants may be the primary source contributing to the present pollution of Mo, Zn, Cd, Cu, and Ni in Tokyo Bay.
