Knowing the polycyclic aromatic hydrocarbons (PAHs) pollution properties in ocean is highly needed to protect the open sea. In July to August of 2020, twenty surface water samples were obtained from the East China Sea to the Philippine Sea. The ranges of ΣPAHs concentrations were 3.188-5.29 ng L in dissolved phase, 0.455-1.305 ng L in particulate phase in the Philippine Sea. 3, 4-Ring PAHs were the most abundant PAHs. Their spatial differences in dissolved phase were mainly caused by human activities, the summer monsoon from the Philippine Islands and the Northern Equatorial Current, and the Kuroshio Current and Subtropical Countercurrent. The source analysis showed that PAHs in surface water in the Philippine Sea may come from coal combustion. It is the first time to analyze the occurrence and distribution of PAHs in the Philippine Sea.
了解海洋中的多环芳烃（PAHs）污染特性对于保护公海非常重要。2020 年 7 月至 8 月，从东海到菲律宾海采集了 20 个表层水样。在菲律宾海，溶解相和颗粒相的ΣPAHs 浓度范围分别为 3.188-5.29ng/L 和 0.455-1.305ng/L。3、4 环 PAHs 是最丰富的 PAHs。它们在溶解相的空间差异主要是由人类活动、菲律宾群岛夏季季风、北赤道流、黑潮和亚热带逆流引起的。来源分析表明，菲律宾海表层水中的 PAHs 可能来自煤炭燃烧。这是首次分析菲律宾海 PAHs 的发生和分布情况。
