Abstract The polycyclic aromatic hydrocarbon (PAH) concentrations in total suspended particulate matter (TSP) samples collected from October, 2021 to September, 2022 were analyzed clarify the pollution characteristics and sources of 16 PAHs atmospheric TSP Bengbu City. ρ(PAHs) ranged 1.71 43.85 ng/m 3 higher detected winter, followed by spring, autumn, summer. positive matrix factorization analysis revealed that, spring summer, PAH was caused mainly industrial emissions, gasoline diesel fuel combustion, whereas autumn it coal, biomass natural gas combustion. cluster potential source factor analyses showed that long-range transport a significant factor. During northern northwestern regions had impact, coastal area south greatest influence health risk assessment annual carcinogenic equivalent concentration values for varied 0.0159 7.437 , which classified as moderate. Furthermore, incremental lifetime cancer 1.431 × 10 −4 3.671 −3 adults 6.823 −5 1.749 children, than standard.

Exposure to fine particles (PM2.5) and associated PAHs are frequently linked with lung cancer, which makes the understanding of their occurrence health risk in human lungs urgently important. Using ultrasonic treatment sequencing centrifugation (USC) extraction method coupled gas chromatography-tandem mass spectrometry (GC - MS/MS) analysis, we revealed molecular fingerprints PM-accumulated from a cohort 68 patients cancer typical air-polluted region, China. Sixteen priority can be grouped by concentrations as ∼ 1 × 104 ng/g (ANT/BkF/ACE/DBA/BgP/PHN/PYR), 2-5 103 (BaP/FLE/NaP/BbF), (IND/Acy/CHR/FLT/BaA). The sum concentration 16 was approximately equaled 13% those atmospheric PM2.5, suggesting significant pulmonary leaching deposited lungs. Low- high-molecular weight accounted for 41.8% 45.1% total PAHs, respectively, indicated that tobacco cooking smoke were likely important sources PAHs. evident increasing NaP FLE PM significantly correlated smoking history among smokers. implicated carcinogenic potency participants aged 70-80 17 times 40-50 on basis BaP equivalent (BaPeq) evaluation. particulate enrichment factor (EFP), PAH content relative bulk tissue, 54 835 averaged at 436. high value EFP suggested essentially accumulated exhibited pattern "hotspot" distribution lungs, would increase monoclonal tumorigenesis. chemical characteristics together risks could provide information effects pollution body.
