Surface sediments and corals (Acropora sp. and Montipora sp.) from the coastline of Kenting were analyzed in 2009 and 2010 for content levels of polycyclic aromatic hydrocarbons (PAHs) using gas chromatography-mass spectrometry. The total PAH concentrations (t-PAH) in corasls (143-1715 ng g(-1) dw) were significantly higher than in the ambient sediments (2-59 ng g(-1) dw) indicating the bioaccumulation of PAHs in corals. The spatial and seasonal variation in PAH levels suggested that land-loaded contaminants may be the main source of PAHs in the Kenting coral reefs. Based on molecular indices, PAHs were substantially of petroleum origin. The major PAH components were phenanthrene, pyrene and fluorine, but PAH congeners in corals and sediments still have characteristic composition patterns which would be altered by the bio/accumulation mechanisms. Further study is essential to assess and understand the impacts of these chemicals on coral reefs.
2009 年和 2010 年，使用气相色谱-质谱法分析了垦丁海岸线的表层沉积物和珊瑚（鹿角珊瑚和丛生盔形珊瑚）中的多环芳烃（PAHs）含量水平。珊瑚中的总多环芳烃浓度（t-PAH）（143-1715ngg(-1)dw）明显高于环境沉积物中的浓度（2-59ngg(-1)dw），表明多环芳烃在珊瑚中的生物积累。PAH 水平的空间和季节性变化表明，陆地负荷污染物可能是垦丁珊瑚礁中 PAHs 的主要来源。基于分子指标，PAHs 主要来自石油。主要的 PAH 成分是菲、芘和氟，但珊瑚和沉积物中的 PAH 同系物仍具有特征组成模式，这些模式将被生物/积累机制改变。进一步的研究对于评估和了解这些化学物质对珊瑚礁的影响至关重要。
