PAH Contamination, Sources and Health Risks in Black Soil Region of Jilin Province, China

Soils in the Black Soil Zone of northeast China are experiencing pollution from polycyclic aromatic hydrocarbons (PAHs) as the region undergoes urbanization. In this study, 119 topsoil samples were collected from the black soil agricultural area in Jilin Province, China to investigate the characteri...

description Soils in the Black Soil Zone of northeast China are experiencing pollution from polycyclic aromatic hydrocarbons (PAHs) as the region undergoes urbanization. In this study, 119 topsoil samples were collected from the black soil agricultural area in Jilin Province, China to investigate the characteristics and spatial distribution of 16 PAHs. The total concentration of ∑16 PAHs in the agricultural soils ranged from 2.546 to 33.993 mg/kg, with a mean value of 9.99 mg/kg. Positive matrix factorization (PMF) analysis indicated that vehicle exhaust and oil combustion were identified as the main contributors to traffic- and energy-related pollution. The inherited lifetime carcinogenicity risk (ILCR) was found to be relatively low, indicating a low potential risk in this region, with adults (1.34 × 10<sup>−5</sup>) exhibiting a higher risk than adolescents (8.62 × 10<sup>−6</sup>) and children (7.49 × 10<sup>−6</sup>). The highest values for intake, skin contact, and inhalation routes were observed in the adult group, suggesting that adult residents in certain areas may be at increased health risk. This study enhances our understanding of the pathways through which PAHs enter agricultural soils in Jilin Province and provides insights that could aid in addressing PAH pollution in black soil, ultimately contributing to more sustainable agricultural practices in the region.
