英文摘要	The total concentrations and component profiles of polycyclic aromatic hydrocarbons (PAHs) in ambient air,surface soil and wheat grain collected from wheat fields near a large steel-smelting manufacturer in Northern China were determined.Based on the specific isomeric ratios of paired species in ambient air,principle component analysis and multivariate linear regression,the main emission source of local PAHs was identified as a mixture of industrial and domestic coal combustion,biomass burning and traffic exhaust.The total organic carbon (TOC) fraction was considerably correlated with the total and individual PAH concentrations in surface soil.The total concentrations of PAHs in wheat grain were relatively low,with dominant low molecular weight constituents,and the compositional profile was more similar to that in ambient air than in topsoil Combined with more significant results from partial correlation and linear regression models,the contribution from air PAHs to grain PAHs may be greater than that from soil PAHs.; The total concentrations and component profiles of polycyclic aromatic hydrocarbons (PAHs) in ambient air,surface soil and wheat grain collected from wheat fields near a large steel-smelting manufacturer in Northern China were determined.Based on the specific isomeric ratios of paired species in ambient air,principle component analysis and multivariate linear regression,the main emission source of local PAHs was identified as a mixture of industrial and domestic coal combustion,biomass burning and traffic exhaust.The total organic carbon (TOC) fraction was considerably correlated with the total and individual PAH concentrations in surface soil.The total concentrations of PAHs in wheat grain were relatively low,with dominant low molecular weight constituents,and the compositional profile was more similar to that in ambient air than in topsoil Combined with more significant results from partial correlation and linear regression models,the contribution from air PAHs to grain PAHs may be greater than that from soil PAHs.; The present study was supported by the Natural Science Foundation Committee of China; the National Basic Research Program of China; the Science & Technology Basic Special Fund of China; “111” Project (No.B14001) of Peking University; 7; 93-103; 57
