| Abstract: | Grab samples of wastewater and sludge from each unit of process train of an A/O municipal wastewater treatment plant were analyzed,focusing on PBDEs(polybrominated diphenyl ethers).The study involved extraction,purification and concentration and finally the analysis using GC/MS.The findings indicated that PBDEs are detectable in all the samples, mainly contained in sludge of the secondary sedimentation tank,and PBDE-209 among others accounts for ca.90%of the total PBDEs followed by PBDE-48 and PBDE-99. |
