1 sie 2024 · Uranium is a naturally occurring radionuclide with chemical toxicity, derived from deposits formed through complex processes. 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.
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 in...
3 sty 2020 · The data in table 2 show that 238 U concentrations in soils in areas with normal natural radiation background vary from 0.4 t o 20 mg kg -1 . The highest mean values of 20.1 + 2.5 mg kg -1 were...
1 mar 2024 · Biochar, a carbonaceous material derived from biomass pyrolysis, exhibits considerable potential for remediating uranium-contaminated soils. However, a comprehensive review of the effects of biochar on the fate and accumulation of uranium in soil–plant systems remains conspicuously absent.
Different studies have identified the various sources of Uranium, explored, and explained the geochemistry of Uranium in soil, assessed the Uranium uptake and toxicity to the plants, and further studied the impact on human health.
to discuss biogeochemical cycling, sources, impact of soil properties on uranium immobilization and dierent remediation techniques involved in U treatment. Method This review synthesized the available evi-dence of potential sources of Uranium, remediation techniques, and biogeochemical cycling, and further discussed the impact of soil ...
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 sources of soil U contamination and their significant spatial variations in surface soils globally based on 789 soil sampling sites collected from 76 studies.
