摘要
为研究安宁河流域多环芳烃(PAHs)的分布特征及风险评价,该文利用气相色谱质谱联用仪(GCMS)测定了安宁河西昌到德昌站点的沉积样中16种PAHs的含量。结果显示:在本研究中测得的沉积物样本中每个组分的PAHS含量较低,主要检出3种多环芳烃组分:Naphthalenamine、phthalate和Docosenamide;PAHs含量在垂向上整体呈现出低-高-低的模式;安宁河沉积物PAHs污染主要来源于原油和石油制品泄漏;按照沉积物质量标准方法,沉积物中多环芳烃单体含量不超过临界效应浓度,仍处于无公害阶段。
In order to study the distribution characteristics and risk assessment of polycyclic aromatic hydrocarbons(PAHs) in Anning River Basin, the contents of 16 PAHs in sedimentary samples from Xichang to Dechang stations of Anning River were determined by gas chromatography-mass spectrometry(GCMs). The results showed that the PAHs contents of each component in the sediment samples measured in this study were low, and three polycyclic aromatic hydrocarbons were mainly detected: naphthalenamine, phthalate and docosenamide;The PAHs content showed a low high low pattern in the vertical direction;PAHs pollution in sediments of Anning River mainly comes from the leakage of crude oil and petroleum products;According to the sediment quality standard method, the content of PAHs monomer in sediment does not exceed the critical effect concentration value, and it is still in the pollution-free stage.
