“…The concentrations of PCDD/Fs in Xijiang (a tributary of the Pearl River; Fig. S1) were 20.4e76.2 pg/L with I-TEQ in the range of 0.012e0.075 pg/L (Liu et al, 2008), which were greater than those in the Elbe River, Germany (0.12e0.28 pg/L) (Götz et al, 1994) and the Hudson River, USA (2.35 pg/L) (Lohmann et al, 2000) but lower than those detected in Matsuyama's (Japan) river (nde1500 pg/L) (Seike et al, 1998).…”

“…are situated close to these rivers, resulting in the release of PBDEs, PCBs and PCDD/Fs into the aqueous system. Some regional studies have revealed the POPs pollution in the aquatic systems around China, including water (Guan et al, 2007;Liu et al, 2008), fish (Han et al, 2007;Wei et al, 2011), sediment (Chen et al, 2006;Li et al, 2014;Shen et al, 2006;Sun et al, 2005), etc. The results suggested occurrence of bioaccumulation and biomagnification of POPs in aquatic biotas, which may threaten human health, especially for the local inhabitants.…”

“…In a previously published paper (Li et al, 2011), the suspended particle concentration in Dongting Lake was found to be 141.08 ± 31.46 mg L À1 , and the average water temperature during the sampling period was found to be 10.1°C. Liu et al (2008) determined PCDD/F concentrations in water, suspended particulate matter (SPM), and water + SPM samples from the Xijiang River, and they calculated the water/water + SPM concentration ratios for different PCDD/F congeners and homolog groups. We can roughly estimate the ratios of PCDD/F concentrations in the water to suspended particles were 3.9-65.4% in the water samples of this study.…”

“…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).…”

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.
