本文对短尾剪羽（Puffinus tenuirostris）初生羽毛中的汞浓度（[Hg]）和氮稳定同位素比值（δ 15 N）进行了测定。在非繁殖期，14只在鄂霍次克海和北方日本海活动的鸟类体内[Hg]最高（2.5 ± 1.4 μg/g），9只在白令海东部活动的鸟类体内[Hg]最低（0.8 ± 0.2 μg/g），5只在两个区域活动的鸟类体内[Hg]居中（1.0 ± 0.5 μg/g），δ 15 N没有影响。结果表明，海鸟样本可以提供一个有用的手段，监测污染在一个大的空间尺度。
We measured mercury concentrations ([Hg]) and nitrogen stable isotope ratios (δ15N) in the primary feathers of Short-tailed Shearwaters (Puffinus tenuirostris) that were tracked year-round. The [Hg] were highest in 14 birds that used the Okhotsk and northern Japan Seas during the non-breeding period (2.5 ± 1.4 μg/g), lowest in nine birds that used the eastern Bering Sea (0.8 ± 0.2 μg/g), and intermediate in five birds that used both regions (1.0 ± 0.5 μg/g), with no effects of δ15N. The results illustrate that samples from seabirds can provide a useful means of monitoring pollution at a large spatial scale.
