Selenium (Se) recovery for technological applications from environmental matrices based on biotic and abiotic mechanisms

Allotropy of selenium nanoparticles: Colourful transition, synthesis, and biotechnological applications

“…Se toxicity is due to its ability to substitute for sulfur (leading to dysfunctional macromolecules) and to the production on reactive oxygen species (ROS) (Ohlendorf et al, 2020 ). Selenium contamination of different environmental compartments (atmosphere, geosphere, hydrosphere) can originate from both anthropogenic and natural activities including mining, agricultural drainage water, fertilization, radioactive waste from power plants, petroleum refining, fossil fuel residues, or volcanic activities (Floor et al, 2013 ; Staicu et al, 2017 ; Wang et al, 2022 ) (Figure 3 ). Se oxyanions (+IV and + VI) are usually present at relatively low concentrations in nature (He et al, 2018 ; Wang et al, 2022 ).…”

Se oxyanions (+IV and + VI) are usually present at relatively low concentrations in nature (He et al, 2018 ; Wang et al, 2022 ). Concentrations ranging from 0.15 to 4.73 μg L −1 Se IV have been detected, for example, in ground waters from Chandigarh (India) (Bajaj et al, 2011 ).…”
