为了研究渤海湾及其邻近河流表层沉积物中有机质的分布、组成和来源，对渤海湾及其邻近河流表层沉积物中的脂肪烃、多环芳烃和生物标志物进行了分析。结果表明，人类活动输入的有机质比自然过程输入的有机质对其分布的影响更大。石油类污染是正构烷烃的主要来源，主要来自海洋石油开采和河流污染物的排放。多环芳烃主要来源于火成源，而黄河口部分采样点的多环芳烃主要来源于岩石源。毒性评价结果表明，渤海湾及其邻近河流表层沉积物中的多环芳烃不会对沉积物产生直接的不良生物效应。
Surface sediment samples from Bohai Bay and its adjacent river, China, were analyzed for aliphatic hydrocarbon, PAHs and biomarkers in order to determine the distribution, composition and source of organic matter in a coastal environment. Results suggested that the input of organic matter from anthropogenic activities has a more significant influence on its distribution than that from natural processes. Petroleum contamination, mainly from offshore oil exploration and discharge of pollutants from rivers, was the main source ofn-alkanes. PAHs were mostly of pyrogenic origin; while some sites in Yellow River Estuary were derived mainly from the petrogenic sources. The toxic assessment suggested that the PAHs in surface sediments will not cause immediately adverse biological effects in sediments from Bohai Bay and its adjacent river, China.
