“…By contrast, the large particles contributed a majority of the total calculated surface area and mass (constant density 2.3 g cm −3 , spherical morphology assumed). This was similar to the findings of Sansalone et al (1998), where 2<d p <9500 μm particles were studied. In that study, particles with diameters less than 25 μm were optically separated based on light obscuration.…”

“…Specific surface area, both measured and calculated, generally increased with decreasing particle size, however total surface area peaked between 425-850 μm. In comparing measured vs. calculated specific surface areas, the trends were similar, but the difference was roughly 1000-fold (Sansalone et al, 1998).…”

“…Suspended and dissolved solids concentrations and particle size distribution have been observed to vary during the course of an event (Sansalone et al, 1998;Li et al, 2005). The grab samples provided a "snapshot" of that variability, while the vacuumed road dust samples served as composite sample.…”

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

“…Road-deposited sediments (RDS) are ubiquitous and important carriers of diffuse urban pollutants (Sansalone et al, 1998;Sartor and Boyd, 1972;Sutherland, 2003). With the rapid urbanization and industrialization that has occurred in China and other developing countries, urban diffuse pollution caused by RDS wash-off has been recognized a major problem in urban areas (Li et al, 2013;Lu et al, 2009;Zhao et al, 2011).…”

“…Heavy metals get into water as a result of storm runoff flow and as a result of rainfall washing heavy metals from dust in the air [5]. Some studies have shown that particles originating from traffic are easily flushed from the ground surface by storm runoff [6]. It was found that surface runoff of storm runoff can contain over 120 µg/l of Zn and 20 µg/l of Pb [7].…”

Geostatistical study of spatial correlations of lead and zinc concentration in urban reservoir. Study case Czerniakowskie Lake, Warsaw, Poland

Abstract:The article presents detailed geostatistical analysis of spatial distribution of lead and zinc concentration in water, suspension and bottom sediments of large, urban lake exposed to intensive anthropogenic pressure within a large city. Systematic chemical measurements were performed at eleven cross-sections located along Czerniakowskie Lake, the largest lake in Warsaw, the capital of Poland. During the summer, the lake is used as a public bathing area, therefore, to better evaluate human impacts, field measurements were carried out in high-use seasons. It was found that the spatial distributions of aqueous lead and zinc differ during the summer and autumn. In summer several Pb and Zn hot-spots were observed, while during autumn spatial distributions of Pb and Zn were rather homogenous throughout the entire lake. Large seasonal differences in spatial distributions of Pb and Zn were found in bottom sediments. Autumn concentrations of both heavy metals were ten times higher in comparison with summer values. Clear cross-correlations of Pb and Zn concentrations in water, suspension and bottom sediments suggest that both Pb and Zn came to Czerniakowskie Lake from the same source.
