| Abstract: |
| To clarify the concentrations of PAHs in the soil of agricultural product planting bases in Liaocheng City and its impact on the environment and human health, this study analyzed the content, compositional characteristics, correlations, and sources of 16 polycyclic aromatic hydrocarbons（PAHs）in the soil of Shenxian County, a key vegetable and fruit planting base in Liaocheng, and assessed the ecological-health risks associated with PAHs in the soil. The results showed that：The average mass concentration of 16 PAHs（∑PAHs） in the soil was 162.0 μg·kg-1, with high-ring PAHs being predominant. The total mass concentration of PAHs in the summer was higher than in the winter. The correlation among high-ring compounds was stronger than that among low-ring compounds. The main source of PAHs in winter was coal/biomass combustion, while in summer, the primary source was liquid fossil fuel combustion. The soil in the study area was slightly polluted in summer and unpolluted in winter. The carcinogenic risk of PAHs under the three pathways did not exceed the standard value. |
