Polychlorinated dibenzofurans/dibenzo-p-dioxins (PCDF/PCDDs) and other dioxin-like substances in marine organisms from the Grenland fjords, S. Norway, 1975–2001: present contamination levels, trends and species specific accumulation of PCDF/PCDD congeners

Polychlorinated dibenzo-p-dioxins, dibenzofurans and biphenyls in fish from the Netherlands: concentrations, profiles and comparison with DR CALUX® bioassay results

“…The profile reported by Gomara et al [29] on mussel samples from the Spanish market were very similar to our data. Bayarri et al [28] reported a different pattern (2,3,4,7,3,7,8-TCDF as almost the only PCDD/F congeners present) in mussels from the Adriatic Sea, which is characteristic for that location as was also observed in other fish. Concerning the herring cluster (cluster 4), the predominance of 2,3,7,8-TCDF, 2,3,4,7,8-PeCDF and 1,2,3,7,8-PeCDD determines the deviating profile compared with that for other fish from the English Channel and the North Sea.…”

“…Compared with other food items, fish can bioaccumulate considerable amounts of these contaminants [3]. The presence of PCDD/Fs and DLPCBs in regularly consumed fish or in fish originating from point sources has been demonstrated [4][5][6][7][8]. The Dutch rivers Meuse, Rhine, Waal and IJssel are highly polluted with PCBs and dioxins owing to a high degree of urbanization and industrialization along these rivers in the Netherlands, Germany, France and Belgium.…”

Dietary exposure to polychlorinated dibenzo-p-dioxins and dibenzofurans via fish consumption and dioxin-like activity in fish determined by H4IIE-luc bioassay

“…Table S1 (Supplementary data) compares PCDD/F concentrations in fish collected from GY to be up to 375 times higher than those observed in almost all other regions in China Hsu et al, 2007;Jiang et al, 2007;Wan et al, 2005;Zhang et al, 2007Zhang et al, , 2008, including Ya-Er Lake which had been seriously polluted with hexachlorocyclohexane and hexachlorobenzene effluent discharged from a large chemical plant (Wu et al, 2001). The values of GY fish were similar to those of marine fish from the USA (Brown et al, 2006), Norway (Knutzen et al, 2003), the Baltic Sea (Shelepchikov et al, 2008) and Australia (Padula et al, 2008). Fish collected from TZ showed comparable concentrations to those from Shenzhen (Zhang et al, 2008), the Pearl River Delta , Italy (Taioli et al, 2005), Japan (Kajiwara et al, 2007), Korea (Moon and Ok, 2006), and the Netherlands (DeMul et al, 2008).…”

Pesticide Use in South Africa: One of the Largest Importers of Pesticides in Africa

“…Analytical details are given in Bengtson Nash et al(2008) and Knutzen (2003). In short: samples were spiked with 13 Clabelled analogs of the analytes and extracted with cyclohexane.…”
