[Polybrominated diphenyl ethers in camphor bark from speedy developing urban in Jiangsu Province].

Polybrominated Diphenyl Ethers (PBDEs) were measured in camphor bark samples from 40 locations in Suzhou, Nantong and Wuxi, Jiangsu Province. The samples were extracted by accelerated solvent extraction (ASE) and analyzed using gas chromatography/mass spectrometry (GC-MS). The 8 PBDEs were detected in all samples and the average concentrations of total PBDEs (BDE28, 47, 100, 99, 153, 154, 183, 209) was 835 microg/kg lipid weight (ranged from 112 to 7 460 microg/kg lipid weight).
