Increasing pollution pressures were placed in the coastal and estuarine ecosystems in China because of the elevated pollutants discharged from various sources. Polycyclic aromatic hydrocarbons (PAHs) in the environment were closely linked to human activities, which have been intensively studied for their geochemical interest as markers. In this review, the status of PAH contamination in China Sea was assessed by comprehensive reviews of the concentrations, sources, and fates of PAHs in sediments of China Sea. PAH concentrations in China Sea sediments decreased from north to south due to the higher emissions in North China. Atmosphere was probably the main carrier of PAHs in the north due to the higher contents of atmospheric fine particles and higher wind speeds. However, riverine inputs were probably the most important sources of PAHs in the coastal sediments of South China due to higher rainfall.
由于各种来源排放的污染物增加，中国沿海和河口生态系统承受了越来越大的污染压力。环境中的多环芳烃（PAHs）与人类活动密切相关，由于其作为示踪物的地球化学意义，已受到广泛研究。在本综述中，通过综合评估中国海沉积物中 PAHs 的浓度、来源和归宿，评估了中国海的 PAH 污染状况。由于华北地区排放量较高，中国海沉积物中的 PAH 浓度从北到南逐渐降低。由于大气细颗粒物含量较高和风速较高，大气可能是北方地区 PAHs 的主要载体。然而，由于降雨量较高，河流输入可能是华南沿海沉积物中 PAHs 的最重要来源。
