Abstract:Petroleumhydrocarboncontamination(PHC）representsoneofteenvironmentallycriticalpolltionconcersdomesticaly and internationally.Risk assessment was performed through analysis of C6-C9 PHC contamination characteristics at a printing enterprise retired site，utilizing the single factor indexmethod (Pi) ，nemerow comprehensive index method(Ni)and geo-accumulation index meth（204 od(Igeo) .The results show that Soil C6-C9 PHC concentrations ranged from 0.02 to 15000mg/kg ，exceeding the detection threshold stipulated by Beijing's local standards.The highest contamination concentration( 15000mg/kg )occurred in deepsoil layers.With increasingsoileptctisiallsddbtleasdatigadatird substratum.Maximum index values reached Pi=65.22 ， Ni=46.35 ，and Igeo=5.442 ,demonstrating substantial soil contamination by C6 （204 （20 -C9 PHCs.
