Distribution Characteristics of Polycyclic Aromatic Hydrocarbons in theSuspend Particle of Rivers from Tongzhou District of Beijing

  • 摘要: 2005年7月—2006年3月用GC-MS内标定量法检测了北京市通州区23个采样点河流悬浮物样品中16种优控多环芳烃(PAHs)含量,并探讨了研究区域悬浮物中PAHs的分布特征.结果表明,通州河流悬浮物中w(PAHs)为1 160.60~27 653.72 ng/g,其中12月最高,10月最低;不同河流之间悬浮物中PAHs含量的差异较大,其中北运河通州河段悬浮物PAHs污染源分布较多;悬浮物中16种PAHs以3环PAH为优势组分,3环及3环以下PAH占PAHs的70%左右;采样点PAHs含量与4环PAH含量有显著的正相关关系,回归分析得到相关度很高的一元线性关系式.
