“…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.…”

“…reported that the median serum dioxin-like chemical concentrations (including those of 17 PCDD/Fs and 9 PCBs) for 2361 American subjects aged 40 or older was 19.2 WHO 2005 -TEQpg/g lipid. According to many studies of concentrations of dioxin-like in foodstuffs, the contribution of PCDD/Fs and dioxin-like PCBs to WHO-TEQ varied (Marin et al, 2011;Storell et al, 2011;Wei et al, 2011;Chang et al, 2012;Zhang et al, 2013). Therefore, one cannot compare this study's analytical results with those for American populations because of the different components in TEQ.…”

This study combined ambient air sampling and biomonitoring data to determine the PCDD/Fs exposure levels and health risk for residents near a Waelz plant. In total, 457 adults completed questionnaires and 48 subjects also gave blood samples. We The estimated lifetime average daily doses (LADDs) were 1.20 and 1.09 pg WHO1998-TEQ/kg/d, which are below the tolerable daily intake (TDI) range of 1-4 pg TEQ/kg bw (World Health Organization). However, the concentration was higher than concentrations for the general population in Taiwan. The USEPA multimedia model showed that the median of lifetime exposure to PCDD/Fs was 1.90 × 10 -2 pg/kg bw/day and 3.19 × 10 -2 pg/kg bw/day for Area U (upwind site) and Area D (downwind site), respectively. The carcinogenic risk was 2.96 × 10 -6 (95th percentile = 1.61 × 10 -5 ), and 4.97 × 10 -6 (95th percentile = 2.59 × 10 -5 ) for Area U and Area D, respectively. In summary, residents near the plant had a higher body burden of PCDD/Fs than the general population in Taiwan. The health risk from exposure, including cancer mortality caused by chronic exposure to PCDD/Fs, needs to be clarified further.

“…The PCDD/F WHO-TEQs were in the same magnitude with the fish samples that have been found in other fish species taken from the other sites. PCDD/F WHO-TEQs of 0.48-9.05 pg g À1 ww were found in marine fish from near Hong Kong and in the Pearl River Delta, China (Wei et al, 2011), and PCDD/F and ('dioxin-like') PCB WHO-TEQs of 0.05-8.0 pg g À1 ww were found in freshwater fish and eels from Latvian lakes (Zacs et al, 2013).…”

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.
