The concentrations, distribution, possible sources, and @entity5 risks of @entity2555 ( @entity2556 ) in total suspended particles (TSPs) and surface soils collected from the same sampling spots were compared in Kunming, China. The total @entity2556 concentrations were 9.35-75.01  ng/m(3) and 101.64-693.30  ng/g dry weight (d.w.), respectively, in TSPs and surface soils. @entity14368 (FLA), @entity9435 (PYR), @entity12684 (CHR), and @entity11966 ( @entity815 ) were the abundant compounds in TSP samples, and @entity11966 ( @entity815 ), @entity11965 (FLO), @entity14368 (FLA), @entity12685 ( @entity68452 ), and @entity27541 (BghiP) were the abundant compounds in surface soil samples. The spatial distribution of @entity2556 in TSPs is closely related to the surrounding environment, which varied significantly as a result of variations in source emission and changes in meteorology. However, the spatial distribution of @entity2556 in surface soils is supposed to correlate with a city's urbanization history, and high levels of @entity2556 were always observed in industry district, or central or old district of city. Based on the diagnostic ratios and principal component analysis (PCA), vehicle emissions (especially diesel-powered vehicles) and coal and wood combustion were the main sources of @entity2556 in TSPs, and the combustion of wood and coal, and spills of unburnt petroleum were the main sources of @entity2556 in the surface soils. The @entity3014 equivalent concentration (BaPeq) for the TSPs and surface soil samples were 0.16-2.57  ng/m(3) and 11.44-116.03  ng/g d.w., respectively. The @entity5 risk (ILCR) exposed to particulate @entity2556 ranged from 10(-4) to 10(-3) indicating high potential of carcinogenic risk, and the ILCR exposed to soil @entity2556 was from 10(-7) to 10(-6) indicating virtual safety. These presented results showed that particle-bound @entity2556 had higher potential carcinogenic ability for @entity1 than soil @entity2556 . And, the values of @entity5 risk for @entity1 were always higher than for adults, which demonstrated that @entity1 were sensitive to carcinogenic effects of @entity2556 .
