“…The 6-9 μm snowmelt particle fraction contained the highest concentration of heavy metals; the 4-6 μm fraction contained the highest heavy metal concentration in the rain runoff. Tuccillo (2006) found stormwater Cu and Zn in the dissolved phase and in particles d p >5 μm, Pb and Cr in d p >5 μm, and Fe, Al, and Si in d p > 0.45 μm.…”

“…Resuspension by Los Angeles Interstate 405 significantly increased atmospheric particle numbers and metal concentrations, however both returned to urban background levels via dry deposition within 100-150 m of the highway (Sabin et al, 2006). Both dry and wet deposition processes contribute particle bound metals to the aquatic environment, for example via stormwater (e.g., Tuccillo, 2006;Sansalone, 1996).…”

Stormwater particles often provide transport for metals and other contaminants, however only larger particles are effectively removed by typical best management practices. Fine particles and their associated constituents are more likely to reach receiving waters; this merits further investigation regarding the metal contribution of fine (d p <10 μm) and very fine (d p <1.5 μm) particles. Road associated particles were collected by vacuuming a road surface and by collecting highway stormwater runoff. A cell sorter was employed to sort road associated particles into four size ranges: 0.1-0.3, 0.3-0.5, 0.5-1.0, and 1.0-1.5 μm. These very fine particles, along with six particle size ranges (total range <2-63 μm) separated using a settling column, were analyzed for Al, Mn, Fe, Cr, Ni, Cu, Zn, and Pb using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Enrichment factors (EFs), calculated using Al as a basis to represent crustal contributions, were similar for the vacuumed road dust and the stormwater runoff. Fe and Mn were minimally depleted (0.1x) or near Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

Cr, Ni, Cu, Zn, and Pb were moderately (10x) to considerably (>100x) enriched for most size ranges; these metals were most enriched in the very fine fractions (max EF~4900 in Zn, 0.1-0.3 μm). Based on this preliminary study, a cell sorter is an acceptable means of fractionating aqueous particles of diameter 0.1-1.5 μm. In spite of their minimal relative mass contribution, the very fine particles are environmentally relevant due to their mobility and enrichment in potentially toxic metals.. NIH Public Access

In Korea, there have been many studies and progresses on various types of pilot scale or commercialized field scale Best Management Practices(BMP) during the last 10 years. Runoff characteristics of diffuse pollutants from different land uses are well identified and documented. However, for the coastal area connected directly with shoreline, runoff patterns and management schemes of non-point pollution were not fully studied. Recently, coastal area is emerging as a new development axis especially in west coast side of Korea such as Incheon city and Chungnam province, thus urbanized area rapidly increased but there are no buffer zones and BMP facilities to aim at preventing direct discharge of the first flush into coastal sea and beaches. In this study, parking area in Deacheon harbor, Boryeong City in Chungnam Province was selected and rainfall runoff was monitored for two year period in order to examine run-off features from which proper type of BMP suitable for coastal area is proposed. Coastal area usually has a low ground water level and consists of plain land, so that large scale BMP such as storm water retention pond and wetland requiring great excavation works is not best management plan. In addition, monitoring study shows that storm water from the paved parking area has a high salinity compared with those in storm water from the inland. High salinity is detrimental for the vegetation. Therefore, BMP employing least vegetative cover and also in terms of maintenance is a good option such as infiltration trench and porous pavement.

La spéciation physique des métaux rejetés par les effluents d’eaux usées municipales est fortement influencée par les conditions physico-chimiques des eaux réceptrices. Les zones de rejet d’effluents municipaux sont des milieux riches en matières organiques où les métaux sont susceptibles d’être fortement complexés et où la présence de colloïdes peut modifier la bioaccumulation et la biodisponibilité des métaux. La distribution de métaux (Al, Cd, Cu, Fe, Mn, Ag et Zn) a été déterminée dans les fractions dissoute (< 0,45 µm), colloïdale (< 0,45 µm et > 10 kDa) et perméable (ultrafiltrée < 10 kDa) à différents sites le long du panache de dispersion de l’effluent municipal majeur de la ville de Montréal. Les concentrations de métaux sous formes colloïdale et perméable sont généralement élevées près du point de rejet de l’effluent étudié. À cause du type de traitement des eaux usées utilisé par la ville de Montréal, ce rejet est une source importante de fer et plus de 70 % du fer dissous se retrouve sous forme colloïdale. Parmi les métaux traces étudiés, l’Ag, suivi du Cu, étaient les plus fortement associés aux colloïdes près du point de rejet de l’effluent. Les colloïdes, présents dans la phase dite dissoute ou filtrable, peuvent influencer différemment le transport et le devenir des métaux rejetés. La proportion colloïdale diminue toutefois rapidement comparativement à celle perméable lors du mélange des eaux usées avec les eaux réceptrices, ce qui semble indiquer que cette fraction a une importance limitée dans le transport à longue distance des métaux provenant de l’effluent. Les résultats de cette étude précisent le rôle des colloïdes dans le devenir géochimique des métaux lors du mélange des eaux usées de l’effluent avec les eaux réceptrices. L’étude souligne donc l’importance d’évaluer la spéciation physique des métaux dans une étude d’impact environnemental d’une zone de rejet urbain.The physical speciation of metals contained in municipal effluents is significantly influenced by the physical and chemical conditions of the receiving water. Waters in the immediate area of an effluent outfall are rich in organic matter; metals are largely complexed and the abundance of colloids can modify metal bioavailability and bioaccumulation. The distributions of aluminum (Al), cadmium (Cd), copper (Cu), iron (Fe), manganese (Mn), silver (Ag) and zinc (Zn) were determined in the dissolved (< 0.45 µm), colloidal (< 0.45 µm and > 10 kDa) and permeable fractions (ultrafiltered < 10 kDa) at different points within the dispersion plume of the major effluent from the Montreal treatment plant. Concentrations of colloidal and permeable metals were typically high near the effluent outfall. Because of the treatment process used by the City of Montreal, this effluent is a major source of Fe and more than 70% of dissolved Fe is present in colloidal form. Of the metals studied, Ag was most associated with colloids near the outfall, followed by Cu. Colloids found in the so-called dissolved or filterable phase can influence the transpor...
