“…PAHs are released to the environment through anthropogenic activities such as the production and combustion of fossil fuels, and biomass (Omar et al, 2002), and enter surface waters through different pathways including atmospheric fallout, urban runoff, and municipal/industrial effluents (Zhu et al, 2004). The input of PAHs from point sources has gradually decreased because of enhanced discharge control (Schneider et al, 2001), while the input of PAHs from urban stormwater runoff has increasingly been reported as one of the most frequent causes of surface water pollution (Brenner et al, 2002;Murakami et al, 2004).…”

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.

“…In our experiment, we used conceivable concentrations of B[a]P, 5 μg/l and 10 μg/l, the concentrations often detected from the polluted water associated with various pollution sources such as sewage discharges (Zhou and Maskaoui, 2003;Zhang et al, 2004). Particularly, it has been reported that the concentration of B[a]P reaches at 10 μg/l in surface water of rivers and lakes from the pollution survey carried out in surface water of Hangzhou, China (Zhu et al, 2004). Therefore, our results suggest that its short duration in the water column can cause changes in zooplankton community structure in natural rivers and lakes.…”

“…BaP is usually found in exhaust gas produced by the incomplete combustion of fuels, in all smoke resulting from the combustion of organic material and in charbroiled food [6][7][8]. BaP can enter into water bodies mainly via atmospheric fallout, municipal/industrial effluents, urban runoff, and oil spillage [9,10]; it is emitted to the atmosphere from different sources, including industrial processes, combustion of fossils and fuels, and irrational application of pesticide [11].…”

A specific BaP hapten was synthesized and BaP antigens (immunogen, coating antigen) were prepared using diverse methods. Based on these works, a streptavidin-horseradish peroxidase-based enzyme-linked immunological analysis was developed and firstly used to detect BaP. Several physiochemical factors that may influence the assay performance were optimized in the assay. Under optimal conditions, a detection limit of 0.0094 ng mL −1 was obtained and good linearity was achieved within a range of 0.03-35.40 ng mL −1 . Satisfactory recovery of spiked samples (91.12-109.23%) was obtained and the coefficient of variation was acceptable. Finally, the detection results of BaP in environmental and food samples were consistent with those obtained using high-performance liquid chromatography. The proposed immunoassay is reliable and has great potential for detecting trace amounts of BaP.
