“…The results indicated the influence of different combustion condition, dust removal technique, the burn-up of feed coal among CFPPs with different IBPC values Yang et al, 2002;Kong et al, 2011;Masto et al, 2015). Sloss and Smith (1993) reported three formation mechanisms for PAHs during combustion process: 1) the penetration of feed coal containing-PAHs through combustion area without being destroyed; 2) reformation of ring structures; 3) de novo synthesis of PAHs via oligomerisation and cyclisation of acetylenes formed as a consequence of incomplete combustion.…”

“…The operating conditions of CFPPs such as combustion efficiencies and excess oxygen were the key factors controlling PAH emissions, more important than type of coal and plant design (Revuelta et al, 1999;Cheruiyot et al, 2015). Significant variation existed in PAH compositions among the different combustion processes (Yang et al, 2002;Kong et al, 2011). Sohu et al (2009) ).…”

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.

“…4). PC1 explained 77.50% of the total variance and had a high load with BbF, DBA, BaP, Ant, BkF, BaA, Phe, Pyr and Flu, which are typical markers for steel industry pyrolysis or incomplete combustion emissions (Han et al, 2011;Kong et al, 2011;Li et al, 2013). Flu, Pyr, BaA, BaP and Chr are the typical markers for coal combustion , while BkF and BbF are components of fossil fuels associated with their combustion (Kavouras et al, 2001).…”

Twenty-two street dust samples collected from a small steel city, central China, were analyzed for 16 USEPA priority PAHs to investigate the concentration, spatial distribution relationship with black carbon (BC) and Iron (Fe), and the source apportionment and to assess the health risk of these compounds. The mean contents of PAHs, BC and Fe were 4.43 µg g -1 , 12837.97 mg kg -1 , 70205.70 mg kg -1 , respectively. The highest spot was in the surrounding of the E'zhou Steel Plant and the Steel Rolling Mill of E'zhou. The correlation analysis indicated that there was no obvious relationship between Fe with each other, the PAHs significantly correlated to black carbon (BC), which might be caused by the continuous emission sources of iron and steel production. The results of sources identification suggested that PAHs contaminations in street dust were a mixed source of industrial production and traffic emission combustion. The incremental lifetime and cancer risks (ILCRs) of exposing to PAHs in the street dust of the E'zhou city for the three age groups (namely childhood, adolescence, adulthood) fluctuated with in the range of 10 -6 to 10 -4 , indicating a potential of carcinogenic risk for exposed populations.

“…Kong et al (2013) investigated the profile characteristic of PAHs in PM 2.5 emitted from six kinds of coal-fired stationary sources in China and found that BbF is one of the tracers of sinter and InP is one of signatures for industrial boilers and coke oven; Flu and Pyr are tracers for thermal-power station and cement plant with coal as fuel. Chr and BghiP are characteristic of iron smelt (Yang et al, 1998;Kong et al, 2011). BghiP is regarded as a tracer for gasoline vehicles (Kong et al, 2010).…”
