英文摘要	To reveal the pollution levels and estimate the ecological risks of polychlorinated naphthalenes (PCNs) in the East China Sea (ECS), seventy-five surface sediment samples were collected and analyzed by high-resolution mass spectrometry. PCN contents ranged from below detection limit to 261.71 ng/g dry weight (d.w.), with an integrally seaward decreasing trend. Mono-, tetra-, and hepta-CNs were the dominant homologs, and CN-2, CN-73, and CN-75 were the major individual components in most samples. CN-2 presented an obvious boundary with lower contents (16.48 +/- 3.40 ng/g d.w.) in the center of the study area and higher contents (50.88 +/- 10.39 ng/g d.w.) in the north and south of the boundary. The toxic equivalent (TEQ) contents ranged from 0 to 0.212 ng/g, and CN-2 and CN-73 were the predominant contributors to the TEQ.
