23 mar 2022 · Increasing uranium (U) content in soils due to anthropogenic U contamination causes accumulation of U in plants, which greatly increases human health risks. This review identified the diverse...
5 lip 2021 · Uranium displays a higher mobility in alkaline soils than that in acidic soils, indicating that U is mobilized and released into soil solution with increasing pH (Selvakumar et al., 2018). This effect is attributed to the enhanced oxidation of U(IV) (sparingly soluble) to U(VI) (soluble) under alkaline conditions ( Wang et al., 2018a ).
1 sie 2024 · In recent years, uranium utilization activities have increased uranium levels in the soil environment, posing serious threats to soil quality, food safety, and human health. Phytoextraction of uranium contamination is currently a cutting-edge topic that has attracted significant attentions.
few literature reviews that elucidated the impact of soil and microbial properties on uranium immobilization and remediation methods to overcome U contamina-tion in the natural environment. In this review, we tried to discuss biogeochemical cycling, sources, impact of soil properties on uranium immobilization and dierent
1 lis 2022 · Radiological and environmental risk assessments of uranium require knowledge of its immediate and long-term behaviour in the soil system. To better understand U(VI) behaviour in contaminated soil, a mesocosm experiment was conducted from 2018 to 2021 by amending soil with U(VI).
13 cze 2023 · This review synthesized the available evidence of potential sources of Uranium, remediation techniques, and biogeochemical cycling, and further discussed the impact of soil properties on uranium immobilization based on available literature.
5 lip 2021 · Uranium (U), a highly toxic radionuclide, is becoming a great threat to soil health development, as returning nuclear waste containing U into the soil systems is increased. Numerous studies have focused on: i) tracing the source in U contaminated soils; ii) exploring U geochemistry; and iii) assessing U phyto-uptake and its toxicity to plants.
