This study determined concentration levels of polybrominated diphenyl ethers (PBDEs) in sediment samples collected from Jukskei River in South Africa. Final extracts, after concentration and dilution to 200 mu L were analyzed by injecting 1 mu L in the GC-ECD and GC-MS. Results obtained showed good recoveries (73%-114%, with RSD < 17%). The concentrations of aPBDEs in sediment for the seven sampling sites ranged from 0.92 to 6.76 ng g(-1) dry weight and total PBDEs with a total BDE sum of 23.85 ng g(-1) dry weights. Concentrations of PBDEs obtained in the present study are significantly lower than the values reported from developed countries.
