| 摘 要： | 利用GC-MS测定日照近岸海域表层沉积物中多环芳烃(PAHs)浓度,采用低环与中高环PAHs的相对丰度以及同分异构体的比值方法,初步解析出表层沉积物中PAHs主要来自于燃煤(工业燃煤、民用燃煤)、燃油(柴油燃烧、汽油燃烧)、焦化、柴油泄漏、木材燃烧等污染源.通过查阅文献获取上述污染源相关源成分谱,应用降解因子修正后的化学质量平衡模型(EPA CMB8.2)对表层沉积物中PAHs的来源进行定量解析.结果表明研究区域内表层沉积物中PAHs的主要来源为燃煤源(工业燃煤、民用燃煤)、柴油燃烧和柴油泄漏,其相对贡献率分别为75.70%,15.05%和9.25%.

| Abstract: | Polycyclic Aromatic Hydrocarbons(PAHs) in coastal surface sediments from Rizhao offshore area were analyzed by GC-MS.The relative abundance between the low ring PAHs and the median and high ring PAHs as well as the isomeric ratios showed that the main source of PAHs were coal residential(CR),coal power plant(CP),diesel engines exhaust(DE),gasoline engines exhaust(GE),coke oven(CO),diesel oil leaks(DOL) and wood burning(WB).Source profiles were collected from literatures to establish the fingerprints of seve... |
