Has Japan's nuclear sewage been discharged into the sea?

Has Japan's nuclear sewage been discharged into the sea? The Fukushima coast has the strongest ocean current in the world. If Japan discharges nuclear sewage into the sea, radioactive substances will spread to most parts of the Pacific Ocean in less than two months, and to the global waters after 10 years. Has Japanese nuclear sewage been discharged into the sea?

Has Japan's nuclear sewage been discharged into the sea? 1 According to domestic media reports in June 18, on June/kloc-0 17, local time, Japanese Prime Minister kishida fumio visited Fukushima Prefecture for the first time since taking office, and visited the Fukushima Daiichi nuclear power plant of Tokyo Electric Power Company. It is reported that core melting and hydrogen explosion occurred in the Great East Japan Earthquake. After inspecting the status quo of reactor scrapping and water treatment, the new Japanese Prime Minister told the media that "there are still many problems left over, and such accidents must not happen again."

According to another report, regarding the decided policy of entering the sea, Kishida said in an interview with the media, "Seeing that a large amount of treated water is stored in the storage tank, I feel that it can't be delayed any longer. What is important now is to make a transparent explanation. " In addition, he also told the top executives of Dongdian that "the scrapping of the reactor is a prerequisite for reconstruction. I hope to attach importance to the trust relationship with the local area and effectively promote operations. "

It should be noted that on April 13, local time, then Japanese Prime Minister Suga Yoshihide officially decided to filter and dilute the Fukushima nuclear sewage and discharge it into the sea. The discharge time is expected to last for 20 to 30 years. This decision has aroused unanimous condemnation from the international community. As an important stakeholder, China's attitude on relevant issues is very clear. Zhao, a spokesman for the Ministry of Foreign Affairs of China, said that in order to safeguard the international public interest and the health and safety of the Japanese people, China has expressed serious concern to Japan through diplomatic channels, demanding that Japan take a responsible attitude and treat the nuclear waste water disposal at the Fukushima nuclear power plant with caution.

In addition, in early September, takaichi sanae, former General Affairs Minister of the Liberal Democratic Party of Japan, expressed his opposition to the discharge of nuclear polluted water from the Fukushima Daiichi nuclear power plant into the sea at a press conference announcing his candidacy for the presidency. Takaichi sanae pointed out that to a great extent, discharging nuclear sewage into the sea would damage Japan's international image. As long as this risk exists, no emission decision will be made.

Although Fukushima Prefecture had planned to recruit "Internet celebrities" from China and South Korea and invite them to visit Fukushima, the purpose was to improve the public image and promote tourism, so as to achieve the purpose of publicity. However, this decision has aroused heated discussion among Japanese people on social media. Many netizens expressed confusion about the significance of this move, and some even bluntly said, "This is simply putting the cart before the horse! There is no need to take such countermeasures as directly giving up sewage discharge into the sea! "

It is worth mentioning that Reconstruction Agency's budget implementation report shows that the public relations expenditure of Fukushima nuclear accident from 20 18 to 2020 is between 300 million yen and 600 million yen respectively. This year, this public relations expenditure has soared to 2 billion yen, trying to induce the development direction of public opinion and eliminate public doubts. Even so, the Japanese government cannot change the fact that nuclear sewage discharged into the sea will cause great harm to mankind.

German experts pointed out that the Fukushima coast has the strongest ocean current in the world. If Japan discharges nuclear sewage into the sea, radioactive substances will spread to most parts of the Pacific Ocean in less than two months, and to the global waters after 10 years. Greenpeace also warned Japan that the harmful substances in nuclear sewage are extremely stable and difficult to decompose, and the wanton discharge may have serious consequences for the future of all mankind.

Has Japan's nuclear waste water been discharged into the sea? In order to appease the international community, the Japanese government is trying to publicize the safety of nuclear wastewater entering the sea. However, even the nuclear waste water after precise filtration still has an inestimable impact on human health, marine environment and food safety.

The first is tritium, which filters the main radioactive substances in wastewater. Its half-life is 12.5 years. Although the radiation hazard is relatively light, the isotope hydrogen of tritium is a ubiquitous element in living cells, which is easily absorbed by organisms and participates in its metabolic process, and its influence cannot be underestimated.

In addition to tritium, radioactive elements such as cesium 137, strontium 90 and iodine 129 may also exceed the standard. Among them, the half-life of iodine 129 is15.7 million years, which can cause thyroid cancer. The so-called "reaching the pollutant concentration standard after a large amount of dilution" in Japan only means that the immediate toxicity probability of related elements is reduced. As a large amount of nuclear wastewater continues to flow into the Pacific Ocean, the total amount of radioactive materials will not decrease.

After the nuclear wastewater enters the sea, most of the radioactive elements will be absorbed by marine microorganisms, and after circulating through the food chain, some of them will enter the land with aquatic products and appear on the human table; The rest will gradually deposit in the ocean, and may even form high concentration accumulation in specific areas through natural circulation, which will eventually become a long-term hidden danger.

Some Japanese scholars pointed out that the ocean around Fukushima is not only a fishing ground for local fishermen to survive, but also a part of the Pacific Ocean and even the global ocean. There is the strongest ocean current in the world along the coast of Fukushima. Within 57 days from the date of nuclear wastewater discharge, radioactive substances will spread to most parts of the Pacific Ocean, and will spread to the global waters after 10.

In this sense, the discharge of nuclear wastewater into the sea is not only a commercial problem that hits the fishery brands in Northeast Asia and the North Pacific, but also a "survival problem" that affects global fish migration, human health, ecological security and other aspects.

According to the latest polls, about 50% of Japanese nationals oppose the government's plan to expel the sea. At present, the people of Fukushima have held demonstrations in many places, holding high placards such as "the ocean is crying" and "opposing the discharge of tritium-containing wastewater into the ocean", hoping that "the government will not make a unilateral decision".

As one of Japan's close neighbors, South Korea has made it clear that it requires Japan to disclose relevant information without reservation and negotiate with neighboring countries to decide the wastewater discharge plan of nuclear power plants. A spokesman for China's Ministry of Foreign Affairs urged Japan to "realize its responsibility, re-examine the treatment of nuclear waste water from Fukushima nuclear power plant, and not to start discharging at sea without authorization before reaching full consultation and agreement with all relevant countries and the International Atomic Energy Agency".

After the Minamata disease occurred in those years, Japanese nitrogenous fertilizer company has been reluctant to admit that the disease was caused by its own sewage discharge. For decades, victims have been suing related companies, and some patients did not get financial compensation until after their death. 1977, it has been more than 20 years since the first Minamata disease occurred, and the Japanese government began to block and landfill the sea areas with serious mercury pollution.

This is the biggest problem of environmental pollution: more people's lives and health always share the responsibilities that a few people are unwilling to bear.

Today, when the tide of economic globalization is overwhelming, this kind of "responsibility sharing" seems to be more and more common. The historical carbon emission of some developed countries has caused the soaring concentration of greenhouse gases, but now it needs the whole world to deal with it; Fukushima nuclear waste water enters the sea, but people in the Pacific region and even around the world have to pay an incalculable price for it.

In this regard, Sister Island just wants to say that "the fate of mankind is the same" is not a slogan, but a reality closer to reality than ever. The current global environmental governance also needs a new order, a new order that emphasizes responsibility.
