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.
23 mar 2022 · Biogeochemical cycle of uranium (U) in soil-plant system. … Worldwide geographical distribution of the 789 sampling locations of uranium-contaminated soils and dataset of U concentration...
5 lip 2021 · Speciation and bioavailability of U in soil. Uranium speciation and bioavailability drive its biogeochemical behavior in the soil-plant system, which plays a key role in risk assessment and soil remediation studies (Bone et al., 2017, Selvakumar et al., 2018). The BCR sequential extraction technique fractionates heavy metal chemical fractions ...
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).
1 mar 2024 · We illustrate effects of biochar application on uranium immobilisation in soil. We also review the inner mechanisms for uranium immobilisation by biochar including surface complexation, reduction, ion exchange, and physical adsorption.
1 mar 2006 · The uranium concentration in soils is generally less than in the source rock, depending on soil type and maturity. Development of soil profiles is the most efficient process of rock break-down and vadose water with its relatively high P O 2 and P CO 2 is the main agent that accumulates and transports uranium as soluble UO 2 (CO 3 ) 3 − and ...
