Researchers from St. Petersburg State University have found that the South Kuril fishing zone, known for its rich marine biodiversity, is at risk of pollution from the Fukushima-1 nuclear power plant disaster in Japan. The team used advanced modeling to predict that toxic particles could reach the fishing zone within 13 days and peak on day 25, with detectable levels persisting for 90 days. Despite the water being purified before release, it still contains tritium, an radioactive isotope. The ongoing release of this water into the ocean is expected to take 30-40 years and has already led to the detection of tritium in the Pacific Ocean at levels ten times higher than the permissible limit.

St. Petersburg State University on Monday, April 22, published the results of scientists’ research. Experts have studied the waters of the South Kuril fishing zone. This region is rich in various species of marine life and is a promising area for fishing in Russia. In the water area there are: saury, sardine, mackerel, cod fish, flounder, Pacific salmon, as well as crabs, mollusks, echinoderms and others. Scientists have modeled the possible paths of movement of contaminated waters from the damaged Japanese nuclear power plant Fukushima-1 and the mechanisms of transfer of these contaminants to the fishing zone. They came to the conclusion that there is a risk of pollution of the Kuril waters. One of the authors of the study, St. Petersburg State University professor Tatyana Belonenko, said that for the study, a team of specialists built detailed graphs of the speed and intensity of the spread of “dirty” markers based on the time of their launch and arrival at the border of the ...
