Surface sediment samples were collected in He-Ping Harbor and the nearby He-Ping Estuary from 2005 to 2006 to examine spatial and temporal variability in polycyclic aromatic hydrocarbon (PAH) concentrations. The sum of the 16 USEPA priority pollutant PAHs varied from 8 to 312 ng/g dry weight, which was relatively low compared to values obtained from other studies in the world. Regarding temporal changes in the PAH profile, total PAH concentrations in the wet season were lower than during the dry season in He-Ping Harbor. However, the concentration of PAHs exhibited no significant difference in the four seasons in the He-Ping Estuary. PAH concentrations in He-Ping Harbor were higher than those in the He-Ping Estuary. In comparison with sediment quality guidelines, PAH concentrations of sediments in this study were lower than those outlined in the criteria, which suggests no evident adverse biological effects due to PAHs around the He-Ping coast. Ratios of specific PAH compounds calculated to assess the possible sources of PAHs reflect that PAHs in He-Ping Harbor may mainly be from pyrogenic coal combustion.
2005 年至 2006 年，在和平港及其附近的和平河口采集了表层沉积物样本，以研究多环芳烃（PAH）浓度的时空变化。美国环保署优先污染物 16 种 PAHs 的总和在 8 到 312ng/g 干重之间，与世界其他研究相比，这一数值相对较低。关于 PAH 分布的时间变化，在和平港，雨季的总 PAH 浓度低于旱季。然而，在和平河口的四个季节中，PAH 的浓度没有显著差异。和平港的 PAH 浓度高于和平河口。与沉积物质量基准相比，本研究中沉积物的 PAH 浓度低于标准中规定的浓度，这表明和平海岸周围的 PAHs 没有明显的不利生物影响。为评估 PAHs 的可能来源而计算的特定 PAH 化合物比值表明，和平港的 PAHs 可能主要来自于煤的高温燃烧。
