Pacific Tuna Gets Polluted with Radioactivity
A report recently published in the Proceedings of the National Academy of Sciences has revealed that a team of scientists has found a radioactive contamination in the mighty bluefin tuna in the Pacific.
While previously, such polluting components were found in smaller fish and plankton in Japanese waters when a magnitude-9 earthquake had caused a tsunami to occur in March 2011. It had damaged the Fukushima Dai-ichi reactors that released radioactive components.
The researchers have now seen Pacific bluefin tuna as contaminated with nearly 10 times higher content than that found previously in tuna off the California coast. It is being suspected by the team that the fish are polluted because of radioactivity from Japan's crippled nuclear plant up to 6,000 miles.
Pacific bluefin tuna has the capability to grow up to 10 feet, weighing over 1,000 pounds. Also, these are the largest and speediest fish, which spawn off the Japan coast, moving to east in waters off California, Mexico.
However, it is clear that fish have taken the radioactive substance, it is being said by the U. S. and Japanese governments that these are still safe to consume. "That's a big ocean. To swim across it and still retain these radionuclides is pretty amazing”, said Prof. Nicholas Fisher.
