“…The concentrations of PCDD/Fs in sediments of the Daliao River Estuary were similar to those in the Yongdingxin River Estuary , Yellow River Estuary (Hui et al, 2009); but were lower than those in sediments from the Haihe River Estuary and Dagu Drainage River Mouth (Hu et al, 2005;Liu et al, 2007). The PCB levels in our present study were much higher than those in the Yongdingxin River Estuary and Yellow River Estuary (Hui et al, 2009), similar to Haihe River Estuary , but lower than those in the high pollution area, namely the Dagu Drainage River Mouth.…”

“…As expected, the PCDD/Fs TEQ concentrations in the four sediment samples from Bohai Bay (BH1eBH4) ranged from 8.4 to 58.7 pg WHO-TEQ/g dw with a mean value of 27.1 pg WHO-TEQ/g dw. These concentrations are higher than those measured at the Qingdao Coastal Sea (0.2e4.2 pg/g TEQ dw) (Pan et al, 2008), and the Yellow River and Yangtze River estuaries (0.11e1.01 WHO-TEQ pg/g) (Hui et al, 2009) in China. Similar congener profiles were found in the river sediment and Bohai Bay sediment samples, suggesting that the PCDD/F concentrations in Bohai Bay are contributed by this contaminated site.…”

a b s t r a c tAir, soils and sediments surrounding an abandoned pentachlorophenol (PCP) factory were sampled to determine the levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), unintentionally formed during PCP production. The mean concentration of PCDD/Fs in ambient air was one order of magnitude higher than that of the reference site. A trend of decreasing concentrations with increasing distance from the factory was observed, suggesting this site has a significant influence on the regional ambient air. As for soil samples collected within 3 km from the factory and sediment samples from the adjacent rivers, high levels of contamination were found with WHO-TEQ concentrations of 193 AE 211 pg/ g and 667 AE 978 pg/g, respectively. The PCDD/F homologue profiles of all samples were consistent with those found in the technical product of PCP, with OCDD as the dominant congener. These results indicate PCDD/Fs in the historical contaminated site pose a long-term impact on surrounding environment.

“…Bao et al (1995) reported that OCDD contributed 76% to the Liu et al (2008) reported that OCDD was the predominant congener and that RPCDD concentrations were higher than RPCDF concentrations in water from the Xijiang River, China. OCDD, HpCDD, and OCDF have been found to be the main PCDD/F homologs in sediments from the Yangtze and Yellow Rivers (Hui et al, 2009). The PCDD/F congener profiles found in sediments from the Haihe River, the Dagu Drainage River (Liu et al, 2007), and Taihu Lake (Zhang and Jiang, 2005) also agreed well with the results of this study.…”

h i g h l i g h t sThe PCDD/Fs concentrations in eight water samples from Dongting Lake were determined. PCDD/Fs concentrations were above that allowed by the US EPA. 2,3,7,8-Chlorinated PCDD/F concentration differed in six fish species. The bioaccumulation of PCDD/F congeners cannot solely be explained by their physical-chemical properties. a r t i c l e i n f o a b s t r a c tThere have been few studies of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in environmental water because of the large volume of water required for PCDD/Fs analysis. Water quality directly affects aquatic organisms, and little is known about how PCDD/Fs are transported in aquatic environments. PCDD/Fs were analyzed in eight water samples from Dongting Lake, China, which was contaminated with PCDD/Fs because of sodium pentachlorophenate use between the 1960s and the 1980s. The total PCDD/F concentrations in the samples were 36-345 pg L À1 , and the mean was 191 pg L À1 . Octachlorodibenzo-p-dioxin was the most abundant PCDD/F congener in every sample, contributing 67-95% of the total 2,3,7,8-chlorinated PCDD/F concentrations. The toxic equivalent (WHO-TEQ) concentrations in the samples were 0.17-0.37 pg L À1 , and the mean was 0.28 pg L À1 , which is higher than the Canadian environmental quality guideline (0.038 pg L À1 WHO-TEQ for freshwater) and the United States Environmental Protection Agency water quality criterion (0.014 pg L À1 WHO-TEQ). PCDD/Fs were also determined in six fish species collected from Dongting Lake, to assess the concentrations, accumulation patterns, and potential for toxic effects. The total 2,3,7,8-chlorinated PCDD/F concentrations in the fish samples were 2.2-17.9 pg g À1 (wet weight), and the dominant congeners were octachlorodibenzo-p-dioxin, 1,2,3,4,6,7,8-heptachlorodibenzo-p-dioxin, 1,2,3,4,7,8-hexachlorodibenzop-dioxin, and 2,3,4,7,8-pentachlorodibenzofuran. The PCDD/F WHO-TEQs were 0.10-0.92 ww (3.3-65.3 lw) pg g À1 in different species of fish. PCDD/F congener patterns in fish may be affected by food chain biomagnification and the lipid content of the species.
