摘      要:Soil contamination by polycyclic aromatic hydrocarbons(PAHs)has raised great environmental ***,the information on national wide distribution of PAHs in soil as well as their effect on soil bacterial community are *** this study,16 PAHs weremeasured in 94 soil samples collected across *** total concentration of 16 PAHs(PAHs)in soil ranged from 74.0 to 17,657 ng/g(dry weight basis),with a median value of 200 ng/*** was themajor soil PAH,with amedian concentration of 71.3 ng/*** samples from Northeast China had a higher median concentration ofPAHs(1,961 ng/g)than those from other *** emission and wood/grass/coal combustion were potential sources for soil PAHs based on diagnostic ratios and positive matrix factors analysis.A nonnegligible ecological risk(hazard quotients1)was found in over 20%of soil samples analyzed and the highestmedian total HQs value(8.53)was found in soils from Northeast *** effect of PAHs on bacterial abundance,α-diversity,andβ-diversity was limited in the soils ***,the relative abundance of some members in genera Gaiella,Nocardioides,and Clostridium was significantly correlated with the concentrations of some ***,the bacterium Gaiella Occulta showed potential in indicating soil contamination by PAH,which is worth further exploration.
