“…The results above implied that consideration of particle grain size helped better understand metal risk. In addition, the RDS grain size had an important influence on the mobility of particles and their associated pollutant concentrations (Roger et al, 1998;Murakami et al, 2005;Deletic and Orr, 2009). The amount was another critical factor affecting RDS potential pollutants contribution to water.…”

a b s t r a c tWe applied the traditional risk assessment methods originally designed for soils and river sediments to evaluation of risk associated with metals in road-deposited sediment (RDS) along an urbanerural gradient that included central urban (UCA), urban village (UVA), central suburban county (CSA), rural town (RTA), and rural village (RVA) areas in the Beijing metropolitan region. A new indicator RI RDS was developed which integrated the RDS characteristics of mobility, grain size and amount with the potential ecological risk index. The risk associated with metals in RDS in urban areas was generally higher than that in rural areas based on the assessment using traditional methods, but the risk was higher in urban and rural village areas than the areas with higher administration units based on the indicator RI RDS . These findings implied that RDS characteristics variation with the urbanerural gradient must be considered in metal risk assessment and RDS washoff pollution control.

“…It plays a major role in the transport and bioavailability of metals and hydrocarbons through complexation reactions. Furthermore, organic carbon adsorbed on suspended solid particles increases their sorption capacity for combining with hydrophobic organic substances and some heavy metals such as lead and zinc (Parks and Baker, 1997;Roger et al, 1998). Though these characteristics may be considered beneficial aspects, the organic matter is liable to microbial decomposition, thereby returning the pollutants back to the dissolved phase at a later stage of runoff flow.…”

“…However at the same time it is important that the facilities provided are capable of removing the critical size range of sediments which would be carrying a significant pollutant load. Research has shown that due to their physicochemical characteristics, the finer particulates are more efficient in the adsorption of pollutants and hence will carry a relatively higher pollutant concentration (Andral, 1999;Hoffman et al, 1982;Roger et al, 1998;Sartor and Boyd, 1972). However, outcomes from some studies have noted that the fraction of fine particulates in runoff can be small, and as such the total pollutant load would be smaller when compared to the load carried by the coarser particulates (Marsalek et al, 1997).…”

Urbanisation significantly impacts on water environments with increased runoff and the degradation of water quality. The management of quantity impacts are straight forward, but quality impacts are far more complex. Current approaches to safeguard water quality are largely ineffective and guided by entrenched misconceptions with a primary focus on 'end-of-pipe' solutions. The outcomes of a research study presented in the paper, which investigated relationships between water quality and six different land uses offer practical guidance in the planning of future urban developments. In terms of safeguarding water quality, high density residential development which results in a relatively smaller footprint would be the preferred option. The research study outcomes bring into question a number of fundamental concepts and misconceptions routinely accepted in stormwater quality management. The research findings confirmed the need to move beyond customary structural measures and identified the key role that urban planning can play in safeguarding urban water environments.Keywords: multivariate analysis, stormwater quality management, urban water quality, water quality impacts 3

“…The size of the street dust particles is critical in influencing the potential risk of contamination to the receiving water (Krein and Schorer, 2000). Smaller street dust particles have higher PAH and organic contents due to their greater specific surface area which favors the adsorption of pollutants (Roger et al, 1998). The smaller particles have greater PAH concentrations in the street area since they have less density, higher mobility and less settleability (Aryal et al, 2005;Murakami et al, 2005).…”

Particles of dust washed off streets by stormwater are an important pathway of polyaromatic hydrocarbons (PAHs) into urban streams. This article presented a comprehensive assessment of the size distribution of PAHs in street dust particles, the potential risks of the particles in urban streams, and the sources and sinks of PAHs in the stream network. This assessment was based on measurements of 16 PAHs from the USEPA priority list in street dust particles and river sediments in Xincheng, China. The content of total PAHs ranged from 1629 to 8986 μg/kg in street dust particles, where smaller particles have a higher concentrations. Approximately 55% of the total PAHs were associated with particles less than 250 μm which accounted for 40% of the total mass of street dust. The PAH quantities increased from 2.41 to 46.86 μg/m 2 in the sequence of new residential, rising through main roads, old town residential, commercial and industrial areas. The sediments in stream reaches in town were found to be sinks for street dust particle PAHs. The research findings suggested that particle size, land use and the hydrological conditions in the stream network were the factors which most influenced the total loads of PAH in the receiving water bodies.
