| 摘要: |
| 研究了某地区农田表层土壤中16种PAHs污染状况和来源。结果表明，研究区2012和2016年土壤中PAHs 总平均值分别为1 748 和3 248 ng/g，其值显著高于其他文献研究区。指出，研究区土壤已受到PAHs的污染，土壤中PAHs以3环、4环为主，BbF、BaP、Phe、BaA、Fla、Pyr、Chr、Flu等质量比相对较高，其污染源主要为焦化、煤和天然气的燃烧，此外交通源对多环芳烃污染也有一定的贡献。 |

| Abstract: |
| This study has analyzed the pollution status and characteristics of 16 PAHs in agricultural soil from a certain area in 2012 and 2016 in this paper. The results showed that the total average PAHs in the soil of the study area was 1 748 ng/g in 2012 and 3 248ng/g in 2016 respectively. The concentration level is significantly higher than that of other literature research areas, which implies that the soil of the study area was contaminated by PAHs. The PAHs of the soil in the research area were mainly 3-4 ring PAHs, the contents of BbF, BaP, Phe, BaA, Fla, Pyr, Chr, Flu were relatively high, their pollution source came mainly from coking plants and coal and natural gas combustion, the traffic source also made some contributions to PAHs contamination. |
