Levels of blood haptoglobin (Hp) and interleukin-6 immunoreactive protein (IL-6 ir) were significantly elevated in river otters (Lutra canadensis) inhabiting oiled areas of Prince William Sound, Alaska (USA) following the Exxon Valdez oil spill in 1989. By May and June 1992, however, such differences were not apparent. Mean body mass of otters, adjusted for sex, age-class, and total length with analysis of covariance, differed between oiled and non-oiled areas from 1990 to 1992, but were nearly identical by May and June 1992. We propose that river otters may be recovering from chronic effects that we observed in 1990 and 1991 following the 1989 Exxon Valdez oil spill, but further research is necessary to test this hypothesis.
1989年埃克森·瓦尔迪兹号油轮泄漏事件后，居住在美国阿拉斯加威廉王子湾油污区域的北美水獭（Lutra canadensis）血液中的触珠蛋白（Hp）和白细胞介素-6免疫反应蛋白（IL-6 ir）水平显著升高。然而，到1992年5月和6月时，这种差异并不明显。通过协方差分析对性别、年龄组和全长进行校正后，1990年至1992年期间，油污区域和未受油污区域的水獭平均体重存在差异，但到1992年5月和6月时几乎相同。我们认为，北美水獭可能正在从1989年埃克森·瓦尔迪兹号油轮泄漏事件后我们在1990年和1991年观察到的慢性影响中恢复，但需要进一步研究来验证这一假设。
