Summary

Polybrominated diphenyl ethers PBDEs) have been detected in bird eggs worldwide, and despite increasing concentrations over the past 25 years, toxicological thresholds have yet to be established. We previously reported embryonic survival, and pipping and hatching success in chicken (Gallus gallus), mallard (Anas platyrhynchos) and American kestrel (Falco sparverius) embryos receiving 0.01-20 :g PBDE/g egg. Survival, pipping and hatching success were decreased in kestrels, suggesting that they are more sensitive to PBDEs than chickens and mallards. Adverse effects were detected in kestrels at levels (> 1 :g/g egg) believed to approach environmentally relevant PBDE concentrations. Polychlorinated biphenyl congener 126 (PCB 126) was used [...]
