Distribution and Origin of Polycyclic Aromatic Hydrocarbons (PAHs) in Sediment from the Yellow River

  • 摘要: 根据黄河干流和支流沉积物中多环芳烃(PAHs)的含量,分析了PAHs分布特征.结果表明,黄河支流沉积物中PAHs污染明显大于干流,其顺序为依洛河>汾河>蟒河.PAHs的种类与芳环数分布情况表明,黄河支流中的PAHs主要来源于石油烃类污染,依洛河也存在部分矿石燃料煤不完全燃烧的热解成因.沉积物有机污染物风险评价的结果表明,3条支流处于高生态风险区,对该地区的生物具有较大的不利影响.
