The contents of 16 polycyclic aromatic hydrocarbons (PAHs) and surface sediment properties were analyzed from 31 locations in Dapeng Bay and neighboring rivers (i.e., Kaoping River, Tungkang River, and Lingbeng River) in Taiwan. Principal component factor analysis (PCFA) showed that the most important latent factors are the soil-texture-caused factor, the PAHs-caused factor, and the nutrient-caused factor. Contour maps incorporating factor scores showed that phenanthrene and pyrene of PAHs had the highest content at the entrance of the northern side of the lagoon. Benzo(a)pyrene had the highest content located in the midsection of the Kaoping River and in Dapeng Bay. Moreover, canonical discriminant analysis shows that sediment quality in Dapeng Bay was not similar to the other three rivers. The methodologies and results provide useful information on watershed management and may be applicable to other basins with similar properties that are experiencing similar coastal environmental issues.
本研究分析了台湾大鹏湾及其周边河流（如：高屏溪、东港溪和林边溪）共 31 个采样点的 16 种多环芳烃（PAHs）含量和表层沉积物性质。主成分因子分析（PCFA）表明，最重要的潜在因子是由土壤质地、PAHs 和养分引起的因子。结合因子得分的等值线图表明，在泻湖的北侧入口处，菲和芘的 PAHs 含量最高。在高屏溪和大鹏湾的中段，苯并[a]芘的含量最高。此外，典范判别分析表明，大鹏湾的沉积物质量与其他三条河流不同。该方法和结果为流域管理提供了有用的信息，并且可能适用于其他具有类似性质且正在经历类似沿海环境问题的流域。
