植物修复镭污染土壤的可行性初步分析

Abstract

Abstract: Plant remediation technology has become an effective means of controlling heavy metal and radioactive nuclide contamination due to its low cost and environmental friendliness. ²²⁶Ra produced during uranium mining and smelting is an alpha nuclide with a long half-life. Once released into the environment, ²²⁶Ra may pose a potential threat to human health through food chain. Therefore, studying the absorption and transport mechanisms of ²²⁶Ra in the soil plant system and its influencing factors is crucial for carrying out plant remediation work on ²²⁶Ra contaminated soil. By conducting research on the biogeochemical cycle of radium, the absorption and transport mechanisms of radium from soil to plants, and their influencing factors both domestically and internationally, this study analyzed the plant remediation strategies and feasibility of radium contaminated soil, and proposed suggestions to improve the efficiency of plant remediation of radium contaminated soil.

Key words: phytoremediation, radium, soil, feasibility analysis
