    Abstract
  • 90Sr is recognized to be one of most important artificial radionuclides. A huge amount of radioactive substance (e.g., 90Sr) was released into marine environment after the Fukushima Nuclear Accident (FNA). High 90Sr activity was still observed in the treated wastewater which was stored on site in many tanks. However, 90Sr was rarely investigated in marine environment due to its complicated and time-consuming analytical procedure after the FNA, constraining a comprehensive understanding of the fate of 90Sr in marine environment. We discussed the 90Sr activity and environmental half-life (EHL) in seas surrounding Japan (SSJ) and the South China Sea (SCS) on the basis of previous data and our 90Sr data in seawater and marine biotas (e.g., sargassum, shrimp, oyster, mangrove, reef coral) collected from the SCS during 2015−2018. We found that the EHL of 90Sr in the SSJ was 15.4 years during 1975−2010. 90Sr in the SSJ was significantly elevated after the FNA. Radiation dose rate of 90Sr on marine fish was increased by five orders of magnitude after the FNA relative to the baseline before the FNA. As the downstream basin of the North Pacific Subtropical Gyre, the SCS was not identified with noticeable 90Sr-derived from the FNA. The EHL of 90Sr in the SCS was calculated to be 26.7 years during 1984−2018 based on the compilation of historical 90Sr data. The contrasting patterns of the EHL of 90Sr and 137Cs in the marginal seas and open oceans were attributed to the distinct sources (river input) and sinks (marine biological pump) of 90Sr and 137Cs. In the context of challenge of 90Sr analytical method in marine environment, extremely high 90Sr concentration factor (around 1000 L/kg) was observed in the reef coral skeleton after comparing with concentration factors of 90Sr in more than 10 kinds of marine biotas. Additionally, reef coral is potential to be a reliable 90Sr marine bioindicator with other advantages of easy availability in large quantity, growth at a fixed location, continue record with high resolution, and simple pretreatment. The study of 90Sr in reef coral will not only help to reveal distinct sources and sinks of artificial radionuclides in marine environment, but also provide valuable insights to optimization and improvement of standards/guidelines of marine radioactivity monitoring program.
