文摘

The present study estimated hexabromocyclododecane (HBCD) as a sum of three main isomers (α, β, and γ) and tetrabromobisphenol A (TBBPA) in African penguins (Spheniscus demersus) from Gdansk Zoo and in their sole food, Baltic herring (Clupea harengus), from Gdansk Bay. The average concentration of HBCD in whole herring was 22.0?±?9.9?ng/g lw, whereas TBBPA was approximately 10-fold lower (2.3?±?1.3?ng/g lw). Brominated flame retardants (BFRs) were also found in muscle and liver of herring. The estimated daily dietary exposure of the penguins to HBCD was 252.9?±?113.7?ng, whereas for TBBPA it was 26.3?±?14.9?ng. The ability of BFRs to accumulate in the liver, muscles, fatty tissue, and brain of penguin was confirmed. The highest concentrations of HBCD (326.9?ng·g? lw) and TBBPA (14.8?ng·g? lw) were found in the brain of an adult penguin. The strongest accumulation factor for BFRs was also established for brain tissue, but it showed stronger magnification in muscle than in liver. HBCD and TBBPA were found in penguin guano and eggs, thus showing effective removal from the birds-systems. BFRs content in yolk was approximately ten times greater than in albumen indicating the lipophilic character of these compounds.
