“…Another group of PAHs with five and six rings decreases in their contents with the decrease of particle sizes. This is in contrast with the previous study which shows a reverse relationship between content and particle size for all PAHs (Arditsoglou et al, 2004). This difference can be interpreted by the highly developed internal surface of coarse ash particles, which could enhance sorptive capacity for PAHs, particularly the high molecular weight PAHs (Griest and Tomkins, 1986;Janvijitsakul and Kuprianov, 2008).…”

The levels of trace elements and polycyclic aromatic hydrocarbons (PAHs) in fly ash generated by coal combustion have received considerable attention in recent years, due to their potential environmental impact. Sixteen high priority PAHs and 14 trace elements in coal fly ash were measured. The particle sizes of fly ash showed a bimodal distribution, and most ash particles were within a range of 20-25 µm in diameter. The fly ash exhibited high contents of CaO and SO 3 , which was influenced by the desulfidation treatment of limestone. The Be, Cu, Ni, V, Se, Mo and Cd contents increased significantly with decreasing particle sizes of fly ash, while those of Zn and Pb showed no obvious trends. PAHs with three-and four-rings were the dominate species in all the fly ash. The amount low molecular weight PAHs with two-, three-and four-rings was inversely correlated with the particle sizes of the fly ash.

“…4. The three and four rings PAHs were found to be the predominant species in all fly ash samples, accounting for more than 80% of the total PAHs, which agrees with the data reported by other studies Arditsoglou et al, 2004;Sahu et al, 2009).…”

“…Coal burning for power generation has been considered one of the most significant anthropogenic source of PAHs by some researchers Liu et al, 2002;Arditsoglou et al, 2004;Sahu et al, 2009). PCBs are a kind of classic POPs due to their high lipophilicity, toxicity and difficulty of degradation (Guo et al, 2014;Liu et al, 2014).…”

For the management of coal fly ashes (CFAs) from coal-fired power plants (CFPPs), characterization of PAHs and PCBs in CFAs is imperative. The 18 PAH and 86 PCB congeners in CFAs collected from 18 large-scale CFPPs in China were detected using GC/MS system. The PAH concentrations were in the range of 5.51-70.9 ng g -1 for 16 CFPPs with individual block power capacity as 600 MW (IBPC-600), significantly lower than 886-916 ng g -1 for 2 CFPPs with IBPC as 200 and 300 MW (IBPC-200/300). Both PAH and PCB congeners for 18 CFPPs were dominated by low molecular weight ones. The 3-and 2-ring PAHs, di-, tri-and tetra-PCBs were the predominant homologs. PAH profiles for 16 CFPPs with IBPC-600 were significantly different from other industrial stacks based on higher coefficients of divergence. The BaP-based toxic equivalency (BaPeq) concentration and BaP-based equivalent carcinogenic power (BaPE) for 16 CFPPs with IBPC-600 were 0.834 ng g -1 and 0.570, much lower than corresponding 20.5 ng g -1 and 15.4 for 2 CFPPs with IBPC-200/300. No difference existed for Σ 86 PCBs between CPFFs with IBPC-600 and -200/300, which ranged from 9.60 to 32.1 ng g -1 . Higher mean carcinogenic PAH concentrations for 2 CFPPs with IBPC-200/300 and PCBs-TEQ concentration for 18 CFPPs indicated the application of CFAs as soil amendment should be prohibited. The PAH concentrations for 18 CFPPs were well correlated with the total organic carbon (TOC) values, while PCB concentrations showed not this trend, indicated the different formation mechanism between PCBs and PAHs.

“…Wadge et al (1986) found high levéis of Pb and Cd in the finest fraction of refuse incineration flyash. For elements volatilized during combustión, an inverse relationship of concentration with particle size exists, due to the larger surface area-to-volume ratio of the smaller particles (Arditsoglou et al 2004).…”

We review the evolution, state of the art and future lines of research on the sources, transport pathways, and sinks of particulate trace elements in urban terrestrial environments to include the atmosphere, soils, and street and indoor dusts. Such studies reveal reductions in the emissions of some elements of historical concern such as Pb, with interest consequently focusing on other toxic trace elements such as As, Cd, Hg, Zn, and Cu. While establishment of levéis of these elements is important in assessing the potential impacts of human society on the urban environment, it is also necessary to apply this knowledge in conjunction with information on the toxicity of those trace elements and the degree of exposure of human receptors to an assessment of whether such contamination represents a real risk to the city's inhabitants and therefore how this risk can be addressed.
