Abstract

Recent reports from the Japanese Broadcasting Corporation (NHK) have highlighted concerning developments of the Fukushima nuclear accident. The Fukushima nuclear-contaminated water has commenced injecting seawater, with an estimated 6,000 tons of seawater being injected throughout the day. Additionally, marine fish caught in the harbor of the Fukushima nuclear power plant have been found to contain alarmingly high levels of radioactive substances, surpassing the regulatory limits by 180 times. This situation has raised significant concerns within the international community, particularly regarding nuclear security. In order to make smarter targeted decision-making, and meanwhile to reduce public concern about marine ecological environment and also the seafood in a timely manner, in this commentary article, we have provided a viewpoint for impact and emergency management of nuclear wastewater discharged into the ocean for marine ecological environment security.
