摘　　要：In August 2023,Japan started to dump its 1.3 million tons of radioactive wastewater into the oceans[1,2].Most radioisotopes are claimed to be removed from the wastewater except tritium,which needs further dilution before discharge.However,this dilution does not effectively remove any tritium from the wastewater but serves as a measure to bring its abnormally high concentration down to meet emission standards.The most worrisome situation is that many more bioaccumulative long-lived radioisotopes(BLLRs),such as carbon-14 and cobalt-60,slip through the treatment process.There are attempts to reduce the concentrations of BLLRs via repurification to meet the regulatory standards[3];however,even low levels of these BLLRs can undergo biomagnification of up to 50,000 folds in marine fish species[4].
