Abstract在黄河尾闾河道及河口采集了48个表层沉积物样品,采用GC-MS 检测手段对沉积物中饱和烃进行了定量和定性分析,研究其组成特征、分布和来源,并对该区域石油烃类污染状况进行了初步评价.实验结果表明,黄河尾闾河道表层沉积物中正构烷烃含量为0.21-0.56 μg·g~(-1),河口为0.60-2.44 μg·g~(-1);北断面受石油平台影响,烃类化合物在口门含量较高.此外,黄河尾闾河道与河口表层沉积物中饱和烃主要为石油源和植物源的混合源;河道中陆源与水生源相当,而河口陆源贡献值大于海洋源贡献值.黄河尾闾河道与河口沉积物中有机质成熟度高,反映了研究区域石油烃输入及其衍生物的重要影响.
Other AbstractSaturated hydrocarbons in the surface sediment samples collected from 48 sites in the tail reaches of the Yellow River estuary (YRE) were analyzed by GC-MS, in order to determine the composition characteristics, distribution and sources, as well as preliminary evaluation on the degree of hydrocarbon contamination. The results revealed that the total concentrations of n-alkanes varied from 0.21 to 0.56 mug·g~(-1) from tail reaches, and 0.60 to 2.44 mug·g~(-1) from estuary of the Yellow River, respectively. Moreover, due to the effect of oil platform on north cross-section, the concentrations of hydrocarbons were higher in the entrance. The analysis of n-alkanes characteristic parameters and biomarkers showed the saturated hydrocarbons sources of surface sediments from tail reaches of the Yellow River estuary were mixed sources of petroleum origin and plant source. For tail reaches of the Yellow River, the terrigenous contribution was equal to water biogenic contribution, while the terrigenous contribution was greater than water biogenic contribution for the estuary. The maturity of organic matter in sediments from tail reaches of the YRE was higher, suggesting that the sediments may be affected by inputs of petroleum hydrocarbons and their derivatives.
