Abstract: Nineteen surface river sediments were collected from the Cheng-Yu Economic Zone (CYEZ), and the Polybrominated Diphenyl Ethers (PBDEs) in the sediments were analyzed using GC/MS method. The results showed that the concentrations of ΣPBDEs (sum of BDE-1, BDE-15, BDE-17, BDE-28, BDE-47, BDE-66, BDE-71, BDE-85, BDE-99, BDE-100, BDE-126, BDE-138, BDE-153, BDE-154, BDE-166, BDE-181, BDE-183 and BDE-190) and BDE-209 in the sediments ranged from 0.20 to 6.45 ng/g and from 0.44 to 6.29 ng/g, respectively. The PBDE contamination in the CYEZ was relatively low as compared with other studied areas. The PBDEs in most samples from the CYEZ were dominated by BDE-209, suggesting that a primary source was Deca-BDE technical mixture. Meanwhile, the congener patterns of PBDEs in the sediments from Pengshan Minjiang Bridge and Guandu indicated that the major sources of PBDEs were Penta-BDEs technical mixture for Pengshan Minjiang Bridge and Octa-BDEs technical mixture for Guandu. In addition, some BDE congeners, such as BDE-1, BDE-15, BDE-181, and BDE-190, which were rarely reported in previous works, were frequently detected in these sediments (detectable rate higher than 70%) with relatively high abundance.
