| contents | Spatial-temporal variations of kelp I contents in coastal waters of China before and after the Fukushima Daiichi Nuclear Power Plant accident. Liu, Xiaowen Liu, Jialin Fan, Yukun Xie, Guozhi Sun, Xiaole Zhang, Luyuan Liu, Qi Yang, Xiaoqi Duan, Delin Qiao, Fangli Zhao, Chang Ge, Baozhu Fang, Sheng Zhuang, Shuhan Sun, Weidong Fukushima Nuclear Accident Radiation Monitoring Water Pollutants, Radioactive Kelp China Iodine Radioisotopes Seawater Nuclear Power Plants Spatio-Temporal Analysis Radioactive I isotope, as one of the main products of the nuclear fission process, can be applied to track radioactive substances in the environment. So far, limited studies have investigated the spatial-temporal distribution of I in marine ecosystems including the I isotope released via nuclear activities. This study reports the I concentrations of kelps collected from the shallow coastal Yellow Sea and East China Sea from 2009 to 2021. The results show that the kelp I concentrations increased by 5 times in our studied areas in 2011 right after the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident and then decreased back to the pre-accident level in the following years. Meanwhile, the kelp I concentrations in the Yellow Sea decreased much faster than those in the East China Sea between 2012 and 2021, which could be attributed to large river inputs that sustain a high supply of I to coastal areas. Our observations suggest that the FDNPP accident may not be the cause of the increase in I in coastal kelps in 2011. Instead, the I emitted by nuclear fuel reprocessing plants (NFRPs) and being flushed into coastal areas by rivers could be main source of I to coastal kelps. |
