• Polybrominated diphenyl ethers (PBDEs)
• Sediment core
• Fish tissue
• Distribution
• Nanhu Lake

8 PBDE congeners (BDE-28, -47, -100, -99, -154, -153, -183, and -209) were analyzed at 52 samples including 3 water samples, 43 sediment cores, and 6 fish axial muscle samples collected from a typical urban lake in Central China. The total PBDEs concentration in two sediment cores showed an increasing trend in early sediment layers presented a decreasing trend in more recent layers. The inventory and annual surficial flux of total PBDEs were estimated as 204.9 ng cm(-2) and 5.83ng cm(-2) yr(-1), respectively. PBDEs was not detected in water samples, while BDE99, BDE154, BDE153, and BDE183 were detected in axial muscle of Hypophthalmichthys molitrix and Aristichthys nobilis, with the total PBDEs conccntrations ranged from 1.01 to 2.23ng/g and from 0 (<LOQ) to 2.79ng/g, respectively.
