“…Because anthropogenic combustion processes are a major source of PAHs in soils, soil concentrations have tended to increase over the last 100-150 years, especially in urban areas (Jones et al 1989a(Jones et al , 1989b. Background concentrations for rural, agricultural, and urban soils (from the United States and other countries) are given in Table 5 City contained PAH concentrations ranging from 400 to 10,000 µg/kg (Black et al 1989 (Loehr et al 1993).…”

“…Most PAH are carcinogenic and mutagenic to human and causes serious damage to human health. Although PAHs in ambient air have been studied for a long time in other cities (Jones et al, 1989;Furuuchi et al, 2007;Wang et al, 2007;Tekasakul et al, 2008), few studies had been conducted in Tianjin city which is an important industrial city in China and about 30 millions tons of coal and petroleum were consumed annually. It was found that TSP bound PAHs mainly came from coal combustion in Tianjin in winter .…”

“…In urban ambient air, PAHs are almost entirely emitted from anthropogenic sources (Jones et al, 1989;Caricchia et al, 1999;Mantis et al, 2005). PAHs are usually adsorbed on particulate matter Ravindra et al, 2006;Liu et al, 2009) and can be easily inhaled into the residents' lung as particular matter.…”

Spatial variations were predominantly due to the different strengths of source emission. The total PAHs concentrations at Dongli Monitoring Station (DL) site and Beichen Science and Technology Park (BC) site were higher than those at other four sites in heating period, while those at Meijiang community (MJ) site and Beichen Science and Technology Park (BC) site were higher in no-heating period. Higher PAHs concentrations during heating period and lower concentrations during no-heating period were observed at the six sampling sites, which may be caused by the stronger emissions from stationary combustion sources in heating period and the quicker air dispersion, washout effects, photodegradation and higher percentage in the air in vapor phase in no-heating period. The PAHs concentrations in gaseous phase were predicted with gas/particle partition model, and the BaP and BaP equivalency results indicated that the health risk of gas and particle phase PAHs to human in Tianjin were higher than that in other cities. The contributions from potential sources to PAHs in PM 10 were estimated by the diagnostic ratios between PAHs and principal component analysis (PCA). In whole sampling period, coal combustion was found to the predominant contributor of PM 10 -bound PAHs, followed by vehicles emission and wood combustion.

“…Generally speaking, carcinogenic PAHs are found predominantly in respirable particles. In urban and industrial atmospheres, PAHs are almost entirely anthropogenic (Jones et al, 1989;Guo et al, 2003); giving importance to characterizing potential PAH sources in urban and industrial areas. In China's urban areas, a large amount of air pollution is emitted from natural sources (e.g., soil dust), as well as anthropogenic sources (e.g., coal combustion and vehicle exhaust emission) (Okuda et al, 2004).…”

The presence of particle-associated polycyclic aromatic hydrocarbons (PAHs) was investigated in mixed residential/light industrial, industrial and commercial zones in summer 2000 and winter 2001 in Tangshan, China. Thirteen PAHs were measured with the total average concentrations (ng/m 3 ) of PAHs ranged from 26.5 to 313.6 in summer and from 142.4 to 672.4 in winter. The average concentrations of ∑PAHs were 161.97 in summer and 326.80 in winter. PAH concentrations in mixed residential/light industrial zones were the lowest. Mixed residential/light industrial is a major land-use pattern in many cities in China. This study paid more attention to the source category in the mixed residential/light industrial zone. Particle PAH emissions may be contributed from industrial or domestic activities. Diagnostic ratio analysis, principal component analysis (PCA) and hierarchical clustering analysis (HCA) show major sources to be crude oil (by industrial activities mainly) in summer; and coal combustion (by domestic activities mainly) in winter. In addition, coal combustion was a principal source in the industrial zone. Traffic (combustion engine) was an important source in commercial zones. Finally, analysis by coefficient of divergence got similar results.
