| 摘 要： | 利用盆栽试验方法,研究4种绿化树种对柴油污染土壤中多环芳烃(PAHs)含量的影响,开展修复后土壤PAHs潜在生态风险评价。结果表明:1年后栽培植物土壤中PAHs含量在L1,L2,L3水平下比对照分别降低50.6%,61.4%,43.9%,平均为51.9%,且在3～6个月内PAHs含量减少最快;PAHs组分中以苯并蒽、蒽、芘减少最多,分别达74.8%,69.6%,58.1%。不同树种对PAHs含量影响无显著差异。将平均效应区间中值作为警戒水平,计算得到PAHs的潜在生态风险可能性,结果显示L3污染水平下植物处理中PAHs组分芴、菲、芘的生态风险仍然很高,说明治理PAHs污染最根本的办法是控制PAHs的排放量。 |

| Abstract: | Polycyclic aromatic hydrocarbons(PAHs) are a kind of organic pollutants which chronically remain in environments,and they are particularly concerned because some of them are potent toxic and can pose a carcinogenics risk to humans,and some can be highly persistent in the environment.The aim of this study was to investigate changes of PAHs contents in diesel-contaminated soils and to conduct a preliminary evaluation on the potential risk of residual PAHs after phytoremediation.The results showed that after o... |
