Profiles,exposure assessment and expanded screening of PAHs and their derivatives in one petroleum refinery facility of China
This study investigated environmental distribution and human exposure of polycyclic aro-matic hydrocarbons(PAHs)and their derivatives in one Chinese petroleum refinery facility.It was found that,following with high concentrations of 16 EPA PAHs(∑Parent-PAHs)in smelting subarea of studied petroleum refinery facility,total derivatives of PAHs[named as XPAHs,including nitro PAHs(NPAHs),chlorinated PAHs(Cl-PAHs),and brominated PAHs(Br-PAHs)]in gas(mean=1.57 × 104 ng/m3),total suspended particulate(TSP)(mean=4.33 × 103 ng/m3)and soil(mean=4.37 × 103 ng/g)in this subarea had 1.76-6.19 times higher levels than those from other subareas of this facility,surrounding residential ar-eas and reference areas,indicating that petroleum refining processes would lead apparent derivation of PAHs.Especially,compared with those in residential and reference areas,gas samples in the petrochemical areas had higher ENPAH/EPAHs(mean=2.18),but lower ECl-PAH/EPAHs(mean=1.43 × 10-1)and ∑Br-PAH/EPAHs ratios(mean=7.49 × 10-2),indicating the richer nitrification of PAHs than chlorination during petrochemical process.The occu-pational exposure to PAHs and XPAHs in this petroleum refinery facility were 24-343 times higher than non-occupational exposure,and the ILCR(1.04 × 10-4)for petrochemical work-ers was considered to be potential high risk.Furthermore,one expanded high-resolution screening through GC Orbitrap/MS was performed for soils from petrochemical area,and another 35 PAHs were found,including alkyl-PAHs,phenyl-PAHs and other species,indicat-ing that profiles and risks of PAHs analogs in petrochemical areas deserve further expanded investigation.
