A study lately published in the journal Proceedings of the National Academy of Sciences has revealed that the fish found on the coast of California are polluted.
It has been told by the team of investigators that the fishes, namely Pacific Bluefin tuna, have radioactive contamination. It is being doubted that the pollutants might have been caught while swimming in Japanese waters, when they were moving to the far side of the ocean.
The report has found that a Fukushima nuclear accident had occurred last year and the same had probably released contaminated particles into the water. Following the same, the muscle tissues of 15 Bluefin tuna (Thunnus orientalis) taken from San Diego in August 2011 were tested by the team of inspectors after a couple of months.
It was then found that not one, but each of the fish sample was contaminated with radioactive caesium - the isotopes 134 and 137. As per the team’s say, the content was 10 folds the total caesium radioactivity found in tuna samples before the accident.
Nicholas Fisher, Professor of marine sciences at Stony Brook University, New York, affirmed, "This information might be useful in conservation efforts or in managing fisheries".
