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.
Download scientific diagram | Biogeochemical cycle of uranium (U) in soil-plant system. from publication: A critical review of uranium in the soil-plant system: Distribution,...
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.
10 sie 2020 · This crystallographic correspondence suggests the growth of nanocrystalline uraninite on specific facets of the magnetite about directions that minimize the lattice mismatch (Fig. 2e).
20 mar 2019 · Due to the influence of uranium, the mortality rate has increased. This paper presents the effects of some of the radionuclides that have contaminated the soil, as well as the connection between soil and plants that grow on that soil.
1 mar 2006 · Uranium concentrations in continental rocks range from 2 μg g − 1 in sedimentary rocks to 4–10 μg g − 1 in most granites, while the concentration in basaltic rocks such as ocean ridge basalts, is 2–3 orders of magnitude lower. The uranium concentration in soils is generally less than in the source rock, depending on soil type and ...
