2011年3月11日东日本大地震引发福岛第一核电站事故后，放射性铯（Cs）被释放并广泛分布在东北地区的农田中。放射性铯的半衰期较长，因此放射性铯对农产品的污染将是长期严重危害人类健康的问题。因此，我们对2011年至2014年福岛稻田中的放射性Cs污染水平进行了观测。我们的研究表明，福岛稻田中种植的各种水稻品种的放射性Cs浓度存在很大差异。这些结果表明水稻中铯的积累水平受到基因调控。此外，高氮低钾条件导致秸秆和糙米中Cs浓度增加，表明水稻中Cs积累水平也受到环境因素的控制。
After the Fukushima Daiichi nuclear power plant accident triggered by the Great East Japan Earthquake on March 11, 2011, radioactive cesium (Cs) was released and widely distributed in agricultural field in Tohoku distinct. Radioactive Cs has relatively long half-lives, and thus contamination of agricultural products by radioactive Cs will be long-term serious problem for human health. Therefore, we have observed the levels of radioactive Cs contamination in rice plants grown in Fukushima from 2011 to 2014. Our study demonstrated that there is considerable variation in radioactive Cs concentration among a wide variety of rice cultivars grown in Fukushima paddy field. These results indicated that Cs accumulation levels were genetically regulated in rice plants. In addition, the high nitrogen and low potassium condition produced an increase in the Cs concentration both in straw and brown rice, suggesting that Cs accumulation levels in rice was also controlled by environmental factor.
