英文摘要	Previous studies that have investigated marine oil pollution have predominantly focused on petroleum hydrocarbons. Naphthenic acids (NAs), in contrast, are toxins that are less well studied. Following the Dalian oil spill accident, monitoring surveys were carried out to investigate NAs in Dalian Bay sediments. Concentrations of NAs were between 14.826 and 34.279 mg kg−1, with acyclic and motorcycle carboxylic acids (43.28% and 35.12%, respectively) being the dominant components. NAs were 10–30 times more abundant than polycyclic aromatic hydrocarbons (PAHs) in the sediment. Further correlation analysis showed the abundance of NAs was highly correlated with total PAH levels (0.705, p < 0.01, n = 24) and total oil (0.485, p < 0.05, n = 24), indicating that NAs may be a potential marker for oil pollution in coastal sediments. The present study may help to expand the scope of marine environmental monitoring and provide guidance for the remediation of marine pollutants. © 2019 Elsevier Ltd
