Report: Mutated butterflies found near Fukushima
(CBS News) A group of scientists in Japan made a surprising discovery by
finding large numbers of specimens of pale grass blue butterflies that had
mutated.
In a report in the Scientific Reports journal, the scientists said their
research concluded that "that artificial radionuclides from the Fukushima
Nuclear Power Plant caused physiological and genetic damage to this species.
" The scientists said their findings were not expected.
"It has been believed that insects are very resistant to radiation," lead
researcher Joji Otaki from the University of the Ryukyus, Okinawa, told the
BBC. "In that sense, our results were unexpected."
A magnitude-9 earthquake in March 2011 triggered a tsunami that badly
damaged the Fukushima Dai-ichi reactors. Radiation spewed from the plant
into the ground, air and water nearby for a while until plant workers got
the leak under control.
Japanese officials have long since declared much of the surrounding area
safe for humans, and they even opened a nearby beach for swimmers, but
reports of radioactive - and now mutated - wildlife have been periodically
arising.
In May of this year, U.S. wildlife officials reported finding radioactive
tuna that had made the 6,000-mile journey from Japan. Previously, smaller
fish and plankton were found with elevated levels of radiation in Japanese
waters, although both the tuna and those sea creatures were found to have
levels of radiation below what could harm a human.
The pale grass blue butterflies (Zizeeria maha) that were mutated generally
had smaller wings and irregularly developed eyes, reports BBC.
The scientific team concluced that it wasn't just the consumption of
radioactive food that caused the mutations, but it was also mutated genetics
passed down from older generations that ate radioactive food, BBC reports.
That means that even after the residual radiation from the Fukushima
disaster faded, radiation was still affecting the species' development.
