Brominated flame retardants (BFRs) including polybrominated diphenyl ethers (PBDEs), decabromodiphenyl ethane (DBDPE), and 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), were investigated in common kingfishers (Alcedo atthis) and their prey fish from an electronic waste-recycling site in south China. Elevated BFR residues were detected in the kingfishers, with median concentrations of 8,760, 12, and 7.7 ng/g lipid weight for total PBDEs, DBDPE, and BTBPE, respectively. The calculated predator/prey biomagnification factors (BMFs) were greater than unity for most of the investigated PBDE congeners, with relatively higher values for some hexa-, hepta-, and octa-BDEs (e.g., BDEs 153, 183, 196, 197, 202, and 203). The average BMFs ranged 0.10 to 0.77 and 1.90 to 3.60 for DBDPE and BTBPE, respectively. The BMFs for BTBPE were comparable to or even greater than those for some tri- to penta-BDEs in certain predator/prey pairs, indicating potentially high environmental risks of this compound. Significantly higher concentration ratios of BDEs 202 and 207 to BDE 209 were observed in the kingfishers compared with their prey fish, and these ratios were negatively correlated with the logarithm of BDE 209 concentrations in the kingfishers. This may indicate biotransformation of BDE 209 to BDEs 202 and 207 in these birds. This is the first assessment of the biomagnification potentials of DBDPE and BTBPE in a wild piscivorous bird.
