“…For example, a study by Chang et al [4] evaluated the effectiveness of street sweeping and washing for controlling ambient total suspended particles by experiments, which indicated that the street sweeping and washing process was effective at removing dust and silt from urban roads. However, some researchers such as Vaze and Chiew [5] considered that the contribution of street sweeping to environmental quality was not very clear, and may have an adverse impact because street sweepers did not pick up smaller size particles effectively.…”

“…In this research, it was found that the streets in the industrial area had a greater dust deposition rate and street dust had a higher PAH content. The streets in the industrial area have rough surfaces, resulting in a permanent source of street dust (Pitt et al, 2004) although the dust particles can be cleaned by street flushing (Chang et al, 2005). In contrast, the town streets are hand swept with brooms, a method which is relatively ineffective for removing small particles (Bender and Terstriep, 1984), which have a high PAH resulting in small particles being more easily washed to the stream network.…”

“…Street surfaces are at the same time, sources of urban runoff pollutants and pathways for the transport of pollutants (Sartor and Gaboury, 1984). Street sweepers play an important role in removing litter and debris, but they are relatively ineffective in removing small particles (Chang 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.

“…Street surfaces are both sources of urban runoff pol-lutants and pathways for the transport of pollutants [18]. Street sweepers play an important role in removing litter and debris, but are relatively ineffective at removing smaller particles [19]. Indeed, many studies have shown that the efficiency of conventional street sweeping decreases with grain size [20,21].…”

a b s t r a c tPollutant washoff from road-deposited sediment (RDS) is an increasing problem associated with the rapid urbanization of China that results in urban non-point source pollution. Here, we analyzed the RDS grain size distribution and its potential impact on heavy metal pollution in urban runoff from impervious surfaces of urban villages, colleges and residences, and main traffic roads in the Haidian District, Beijing, China. RDS with smaller grain size had a higher metal concentration. Specifically, particles with the smallest grain size (<44 m) had the highest metal concentration in most areas (unit: mg/kg): Cd 0.28-1.31, Cr 57.9-154, Cu 68.1-142, Ni 25.8-78.0, Pb 73.1-222 and Zn 264-664. Particles with smaller grain size (<250 m) contributed more than 80% of the total metal loads in RDS washoff, while suspended solids with a grain size <44 m in runoff water accounted for greater than 70% of the metal mass in the total suspended solids (TSS). The heavy metal content in the TSS was 2.21-6.52% of that in the RDS. These findings will facilitate our understanding of the importance of RDS grain size distribution in heavy metal pollution caused by urban storm runoff.
