Recent occurrence, distribution and mass inventories of 16 priority polycyclic aromatic hydrocarbons (PAHs) proposed by USEPA in the south Bohai Sea (BS) were studied based on the analytical data of 71 surface sediment samples. The concentrations of 16 PAHs varied from 37 to 537 ngg⁻¹ (dry weight). A clear difference was observed between the coastal Bohai Bay (CBB) and its adjacent BS (ABS) in the distribution and compositions of PAHs. The petrogenic source of phenanthrene in CBB was attributable to the industrial wastewater, fugitive fuel leakages from ships and offshore oil production. Four to six ring PAHs were predominantly from the coal and wood combustions in the whole area. The estimated PAH input to the south BS (43,000 km², 56% of BS in area) was 36.6 ton yr⁻¹, indicating that the study area was one of the important reservoirs of PAHs in world.
基于 71 个表层沉积物样本的分析数据，研究了美国环保署在渤海湾南部提出的 16 种优先多环芳烃（PAHs）的近期发生、分布和质量清单。16 种 PAHs 的浓度范围为 37 至 537ng/g（干重）。在分布和组成方面，渤海湾沿海（CBB）和其相邻的渤海湾南部（ABS）之间存在明显差异。CBB 中菲的生源岩是工业废水、船舶燃料泄漏和海上石油生产。整个地区四到六环 PAHs 主要来自煤和木材燃烧。估计南渤海湾（43000 平方公里，占渤海湾面积的 56%）的 PAH 输入量为 36.6 吨/年，表明研究区域是世界上 PAHs 的重要储存库之一。
