Characteristic Analysis of polybrominated biphenyls and polybrominated diphenyl ethers from municipal sewage sludge in Jiangsu Province

Contents of polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers(PBDEs) from twenty municipal sludge samples of wastewater treatment plants (WWTPs)of the Jiangsu Province in China were determined by gas chromatography-mass spectrometry (GC-MS). The results show that 20 Sludge samples contain polybrominated diphenyl ethers and polybrominated biphenyls; Polybrominated diphenyl ethers range from 11.64 ng/g to 52.35ng/g, with an average content of 29.55ng/g, whose concentration are mostly 20~30ng/g; while PBBs range from 1.36~3.03 ng/g, which PBBs mostly concentrate from 1.5 to 2ng/g. Although the content of PBDES and PBBs were lower than the average level of foreign, more attention should be paid to them.
