摘要

福岛第一核电站(F1NPS)事故发生后,137Cs 活性浓度尚未降至事故前的水平,这是因为事故现场直接释放了 137Cs,而且陆地上沉积了 137Cs 的河流排放物。有必要考虑沿海地区的扩散过程,以了解多河流排放和直接释放的影响。为实现这一目标,我们进行了海洋扩散模拟,考虑了直接释放和河流排放,并将结果与观测数据的年平均值进行了比较。我们假定从河流排放到海洋的 137Cs 微粒在经过混凝沉淀后会迅速再悬浮和再沉淀,并且所有 137Cs 都会被分散。考虑到 2013 年至 2016 年期间除 F1NPS 附近外所有站点的 137Cs 颗粒物的河道排放,结果的可重复性得到了提高。换句话说,河流排放的微粒 137Cs 在相对较短的时间内影响了海洋表面活性浓度的结果。在 F1NPS 附近观测到的 137Cs 活性浓度中,直接释放的影响占主导地位,该浓度被用于估算直接释放量。

Impact of fluvial discharge on 137Cs in the ocean following the Fukushima Daiichi Nuclear Power Station accident
After the Fukushima Daiichi Nuclear Power Station (F1NPS) accident, 137Cs activity concentrations have not yet decreased to pre-accident levels because of direct release from the site and fluvial discharges of 137Cs deposited on land. It is necessary to consider dispersion processes in the coastal area to understand the impact of multiple river discharges and direct release. To achieve this goal, we carried out oceanic dispersion simulations that considered direct release and fluvial discharges and compared the results with the annual averages of observed data. We assumed that particulate 137Cs discharged from rivers to the ocean quickly resuspended and re-leached after coagulation and precipitation, and that all of the 137Cs was dispersed. The reproducibility of results was improved by considering fluvial discharges of particulate 137Cs at all sites between 2013 and 2016, except near the F1NPS. In other words, particulate 137Cs discharged from rivers was found to influence the results of ocean surface activity concentrations within a relatively short period of time. The impact of direct release was dominant for the observed 137Cs activity concentrations adjacent to the F1NPS, which was used to estimate direct releases.

期刊介绍: Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
