The ryukyu, associate professor at the university Long zhang two big led research team found that the first nuclear power plant by fukushima radiation leaks, the effects of the FuDaoXian local a butterfly appeared genetic abnormalities.
The butterfly oxalis corniculata called pulp ash butterfly, often appear in people living near the site of the grass and the fringes of the woods, the adults are all year round.
On march last year the first nuclear power plant fukushima because of the earthquake and tsunami that devastated and serious nuclear leakage. In the same year may and September, the team in FuDaoXian ibaraki prefecture, Tokyo, such as multiple sites oxalis corniculata collection slurry ash butterfly. They let the collection in May 144 only slurry laying eggs and oxalis corniculata ash butterfly hatched larvae. In the process of cultivating these larvae, found that the rock city and wide field such as within the territory of FuDaoXian Harding oxalis corniculata plasma ash butterfly mortality rates than other regions to offspring high, and the high radiation dose of the region, the male butterfly wings size is smaller.
In FuDaoXian oxalis corniculata plasma ash the progeny of butterfly, about 20% of the wings color collocation and spot number appears unusual, unusual frequency is dictated by the 1.5 times. And in September FuDaoXian acquisition in about 240 adults only, its progeny about 50% have such abnormalities.
In contrast, the research team used is considered almost untouched by the impact of a nuclear accident fukushima oxalis corniculata Okinawa slurry ash butterfly, the low radiation doses of radiation experiment, the result also appeared the same abnormalities.
Big Long zhangs second-class people in the latest edition of the journal "science report published the article said, blessed island nuclear accidents on the surrounding environment is the influence, although the insect is that the influence of the radiation dose of low resistance stronger, but this investigation shows oxalis corniculata plasma ash butterfly low resistance.
