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 lis 2022 · In light of the possible hazard of U contamination in soil and groundwater, a thorough knowledge of the long-term geochemical behaviour of uranium in soil systems is urgently needed. Considering the potential risks of U contamination, a mesocosm experiment was setup using a lysimetric tank.
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...
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. Phytoextraction of uranium contamination is ...
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 ...
9 lut 2024 · U concentrations in fertilized and unfertilized soil ranged from 0.8 to 7.3 mg kg − 1 (average 1.1 mg kg − 1) and 0.8 to 8.1 mg kg − 1, respectively. It was observed that over 70% of fertilized soil samples had a higher U concentration than virgin soil samples.
