%X Nineteen surface sediment samples were collected from Liaohe River and analysed for polycyclic aromatic hydrocarbons (PAHs) with GC-MS. The concentrations of 15 detected PAH compounds ranged from 123.5 to 21233.4 ng·g-1 in dry season with the average concentration was 3208.1 ng·g-1; and were 37.9 to 9014.0 ng·g-1 in wet season with the average concentration was 1612.0 ng·g-1. The isomeric ratio method using characteristic compounds of PAHs for source analysis, and the main source was attributed to fuel combustion. Average commercial use of sediment quality benchmarks (mSQG-Q) on the PAHs risk assessment of Liaohe Basin was applied, fluorene and pyrene showed the potential of low-level ecological effects. In wet season, Fushun segment L3-1 points have a higher ecological risk. In dry season, Shenyang segment L1-1 point, Fushun segment L3-1 point and L3-2 point pose a strong negative effect.
