| 英文摘要 | The coking industry is a major industrial source of PAHs and a critical focus of environmental pollution control. To systematically assess the pollution status, spatial distribution, and health risks of PAHs at a decommissioned coking site in North China, 629 soil samples were collected from 0 to 9 m during field surveys in 2022 and 2023, with Sigma 16PAH ranging from 0.25 to 1361.00 mg & sdot;kg-1. An integrated approach combining pollution assessment, source apportionment, and stratified health risk evaluation was applied. The results showed that Sigma 16PAH contamination in the soil was mainly concentrated within the 2-4 m layer, exhibiting vertical heterogeneity and dominated by 4-6 ring PAHs, primarily in the coking and chemical production areas. Source apportionment indicated that PAHs sources varied across soil layers: tar emissions (29.30 %) and coal combustion (28.90 %) dominated the 0-0.5 m, traffic emissions (37.30 %) the 0.5-2 m, and coal combustion plus traffic emissions (51.80 %) the 2-4 m layer. Stratified assessments produced varying risk estimates: under the 0-2-4 m stratification, carcinogenic risk was 8.95 % higher and non-carcinogenic risk was 0.63 % higher than those under the 0-0.5-4 m. Compared to traditional methods, stratified assessment better reflected actual exposure scenarios and led to reductions in adult health risk estimates, lowering carcinogenic risk by 0.64 %-5.69 % and non-carcinogenic risk by 1.18 %-3.15 %.These findings provide a scientific basis for risk identification, remediation strategy formulation, and zone prioritization for similar legacy industrial sites. |
