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 ...
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.
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.
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).
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...
13 lip 2024 · Here, we tested different levels of biochar to help clean uranium-contaminated soil in the potted plants. Adding 1% biochar had the best results in deactivating uranium, increasing soil enzyme activity, and promoting ryegrass growth.
1 sie 2020 · To explore a rapid and economic vitrification technique for preventing uranium migration in soil, microwave technology was used to vitrify the prepared uranium-contaminated soil directly, without complex pretreatment or any modifier.
