Polycyclic aromatic hydrocarbons (PAHs) in coastal surface sediments from Rizhao offshore area were analyzed by gas chromatography-mass spectrometry. A chemical mass balance (CMB) model developed by the U.S. Environmental Protection Agency (EPA), CMB8.2, was used to apportion sources of PAHs. Seven possible sources, including coal residential, coal power plant, diesel engines exhaust, gasoline engines exhaust, coke oven, diesel oil leaks, and wood burning, were chosen as the major contributors for PAHs in coastal surface sediments. To establish the fingerprints of the seven sources, source profiles were collected from literatures. After including degradation factors, the modified model results indicate that diesel oil leaks, diesel engines exhaust, and coal burning were the three major sources of PAHs. The source contributions estimated by the EPA's CMB8.2 model were 9.25%, 15.05%, and 75.70% for diesel oil leaks, diesel engines exhaust, and coal burning, respectively.
采用气相色谱-质谱法分析了日照近岸海域表层沉积物中的多环芳烃（PAHs）。使用美国环境保护署（EPA）开发的化学质量平衡（CMB）模型 CMB8.2 来分配 PAHs 的来源。选择了七个可能的来源，包括煤住宅、煤电厂、柴油机尾气、汽油机尾气、焦炉、柴油泄漏和木材燃烧，作为沿海表层沉积物中 PAHs 的主要贡献者。为了建立这七个来源的指纹图谱，从文献中收集了源特征曲线。在包括降解因素后，改进模型的结果表明，柴油泄漏、柴油机尾气和煤燃烧是 PAHs 的三个主要来源。EPA 的 CMB8.2 模型估计的来源贡献分别为柴油泄漏 9.25%、柴油机尾气 15.05%和煤燃烧 75.70%。
