title: PCDD/Fs and dioxin-like PCBs in sediments from Yellow Estuary and Yangtze Estuary, China.
abstract: Twenty one surface sediments were analyzed for PCDD/Fs and dioxin-like PCBs by HRGC-HRMS in Yellow Estuary and Yangtze Estuary in China. The concentration ranges of 2,3,7,8-substituted PCDD/Fs, dioxin-like PCBs and WHO-TEQ were 2.33-253, 0.04-139 and 0.11-1.01 pg/g dw respectively in sediment from two estuaries. For PCDD/Fs and dioxin-like PCBs, OCDD, CB77, CB105 and CB118 were found to be dominant. The pollution levels in two estuaries were lower compared with that in other locations reported by previous studies.
