福岛第一核电站的倒塌导致大量放射性物质释放到环境中。目前还没有一个迅速和可靠的系统来评估这一事故对动物的生物影响。在这里,我们表明,事故造成了生理和遗传损伤的淡草蓝Zizeeria maha,一个常见的灰蝶在日本。我们于2011年5月在福岛地区收集了第一次化世代的成虫,其中一些表现出相对轻微的异常。第一化性雌性的F1代表现出更严重的异常,这些异常由F2代遗传。2011年9月收集的成年蝴蝶比5月收集的蝴蝶表现出更严重的异常。通过外部和内部低剂量照射,在来自非污染地区的个人身上实验重现了类似的异常情况。我们的结论是,来自福岛核电站的人工放射性核素对该物种造成了生理和遗传损伤。
The collapse of the Fukushima Dai-ichi Nuclear Power Plant caused a massive release of radioactive materials to the environment. A prompt and reliable system for evaluating the biological impacts of this accident on animals has not been available. Here we show that the accident caused physiological and genetic damage to the pale grass blue Zizeeria maha, a common lycaenid butterfly in Japan. We collected the first-voltine adults in the Fukushima area in May 2011, some of which showed relatively mild abnormalities. The F1 offspring from the first-voltine females showed more severe abnormalities, which were inherited by the F2 generation. Adult butterflies collected in September 2011 showed more severe abnormalities than those collected in May. Similar abnormalities were experimentally reproduced in individuals from a non-contaminated area by external and internal low-dose exposures. We conclude that artificial radionuclides from the Fukushima Nuclear Power Plant caused physiological and genetic damage to this species.
