After the discharge of Japanese nuclear sewage, it will reach the coast of China within a certain period of time, and the radioactive substances such as tritium contained in it pose a potential risk to marine ecology and human health. The long-term presence and bioconcentration of tritium may cause internal exposure to the human body, increasing the risk of cancer, malformations, and genetic mutations. This is a serious challenge for Chinese fishermen and consumers.
Dear readers, the recent news about the discharge of nuclear sewage into the sea in Japan has attracted widespread attention. According to reports, the sewage will reach China's coast within 240 days, after which it will take another 1200 days to cover the entire North Pacific. This brings huge risks and losses for Chinese fishermen and consumers.
Japan's nuclear effluents contain a variety of radioactive materials, the most concerning of which is tritium. Tritium is a radioactive hydrogen isotope with a long half-life of about 12.3 years. It has the characteristics of strong penetration, can penetrate plastic and metal, and is difficult to remove or purify by ordinary filtration methods.
Once tritium enters the ocean, it is passed on to marine life and humans through bioaccumulation and the food chain. Long-term tritium may cause internal exposure to the human body, that is, after entering the human body through eating or drinking food or water containing tritium, it will cause damage to cells, DNA and enzymes, and increase the risk of cancer, malformations and genetic mutations.
We must recognize that this poses a potential threat to marine ecology and human health. China's fishermen and consumers will face huge risks and losses. The protection of the marine environment and the adoption of effective responses are therefore essential.
We call on governments, scientific institutions and the international community to work together to strengthen monitoring and assessment to ensure that the impacts of nuclear effluents on marine ecosystems and human health are fully understood and that corresponding protective measures are taken. At the same time, we also need to raise public awareness, strengthen environmental education, and promote sustainable development and environmental protection practices.
