We exposed female European starlings to a pentabromodiphenyl ether (Penta-BDE) mixture through subcutaneous implants, and examined levels and profiles of polybrominated diphenyl ethers (PBDEs) together with reproductive effects. Sum PBDE levels increased significantly in the serum of the exposed females from 218+/-43 to 23,400+/-2035 pg/ml. Sum PBDE concentrations in the eggs of the exposed group ranged from 130+/-12 to 220+/-37 ng/g wet weight (ww). The profile in serum after egg laying was very similar to that in eggs. There were no detectable levels of HO-PBDEs in both serum and eggs. Fewer females of the exposed group initiated egg laying compared to the control group, although the difference was not significant. In addition, egg weight and volume were significantly higher in the exposed group. These results suggest that, at the investigated exposure levels (150 microg sum PBDEs/bird), PBDEs may have a negative effect on reproductive performance.
我们通过皮下植入的方式让雌性欧洲椋鸟接触五溴二苯醚（Penta - BDE）混合物，并检测多溴二苯醚（PBDEs）的含量和分布情况以及生殖效应。暴露组雌性鸟类血清中多溴二苯醚总量从218±43 pg/ml显著增加至23400±2035 pg/ml。暴露组鸟蛋中多溴二苯醚的总浓度范围为130±12至220±37 ng/g湿重（ww）。产蛋后血清中的分布情况与鸟蛋中的非常相似。血清和鸟蛋中均未检测到羟基多溴二苯醚（HO - PBDEs）的含量。与对照组相比，暴露组开始产蛋的雌性数量较少，尽管差异不显著。此外，暴露组的蛋重和蛋体积显著更高。这些结果表明，在所研究的暴露水平（每只鸟150微克多溴二苯醚总量）下，多溴二苯醚可能对生殖性能产生负面影响。
