Legacy　halogenated　compounds,　including　polychlorinated　biphenyls　(PCBs),　polybrominated　diphenyl　ethers　(PBDEs),　and　emerging　organo-halogen　pollutants　such　as　Dechlorane　Plus　(DP),　were　detected　in　fish　from　an　old　industrial　region　in　Northeast　China.　PCBs　and　PBDEs　were　detected　in　all　of　the　samples,　with　concentrations　ranging　from　38.15　to　170.51　ng/g　lipid　weight,　and　9.40-39.69　ng/g　lipid　weight,　respectively.　DP　was　detected　in　more　than　90%　of　the　samples　with　concentrations　ranging　from　not　detected　(ND)　to　470　pg　g/g　lipid　weight.　Compared　with　similar　data　in　other　areas　of　the　world,　PCBs,　PBDEs　and　DP　in　fish　from　Liaohe　River　were　at　medium　or　low　level.　An　unusually　high　percentage　of　PCB-209　was　first　reported　in　the　fish　samples　collected　from　China.　Other　halogenated　pollutions,　such　as　dichlorodiphenyltrichloroethane　(DDT)　and　its　metabolites,　octachlorostyrene,　chlorinated　anisole,　chlorinated　thioanisole,　triclosan-methyl,　and　other　pesticides,　have　also　been　identified　in　the　fish　samples.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
