PCDD/Fs in sprat ( Sprattus sprattus balticus) from the Gulf of Finland, the Baltic Sea

The concentrations and congeners pattern of the polychlorinated dibenzo- p-dioxins (PCDDs) and dibenzofurans (PCDFs) were determined in sprat collected by the commercial catches in the Gulf of Finland, Baltic Sea. Based on the toxic equivalent concentrations 2,3,4,7,8-PeCDF prevailed among the conge...

Description
Summary:The concentrations and congeners pattern of the polychlorinated dibenzo- p-dioxins (PCDDs) and dibenzofurans (PCDFs) were determined in sprat collected by the commercial catches in the Gulf of Finland, Baltic Sea. Based on the toxic equivalent concentrations 2,3,4,7,8-PeCDF prevailed among the congeners of PCDD/Fs. The significance of age- and season-specific relationship between the concentration of lipids and dioxins was demonstrated. On lipid weight basis the concentration of PCDDs was significantly higher in spring than in autumn. This difference was not statistically significant for PCDFs. On lipid weight basis the concentration of dioxins decreased with rising content of lipids. PCDD/Fs toxic equivalent concentration increased with the age of sprat exceeding the EU maximum limit value at more than 5-year-old fish.
