“…Sulfate and nitrate are the two main components of water contamination, and they cause harm to the marine environment. Se is found in industrial effluent in the form of Se(VI) (SeO 4 2− ) and Se(IV) (SeO 3 2− ) oxyanions, which are the main toxic contaminants (Johansson et al, 2015 ). Se in trace amounts is essential for a safe terrestrial and aquatic life; however, increased level of Se in the form of SeO 3 2− , SeO 4 2 and nano-Se is harmful to all living things (Kumar & Prasad, 2021 ).…”

Selenium (Se) is an essential metalloid and is categorized as emerging anthropogenic contaminant released to the environment. The rise of Se release into the environment has raised concern about its bioaccumulation, toxicity, and potential to cause serious damages to aquatic and terrestrial ecosystem. Therefore, it is extremely important to monitor Se level in environment on a regular basis. Understanding Se release, anthropogenic sources, and environmental behavior is critical for developing an effective Se containment strategy. The ongoing efforts of Se remediation have mostly emphasized monitoring and remediation as an independent topics of research. However, our paper has integrated both by explaining the attributes of monitoring on effective scale followed by a candid review of widespread technological options available with specific focus on Se removal from environmental media. Another novel approach demonstrated in the article is the presentation of an overwhelming evidence of limitations that various researchers are confronted with to overcome achieving effective remediation. Furthermore, we followed a holistic approach to discuss ways to remediate Se for cleaner environment especially related to introducing weak magnetic field for ZVI reactivity enhancement. We linked this phenomenal process to electrokinetics and presented convincing facts in support of Se remediation, which has led to emerge ‘membrane technology’, as another viable option for remediation. Hence, an interesting, innovative and future oriented review is presented, which will undoubtedly seek attention from global researchers.

After major pollution by nitrates and pesticides, soils and groundwater in some parts of the world are now facing the emergence of a third major issue of selenium (Se) contamination. Selenium occurrence in ecosystems results naturally from weathering of Se-containing rocks, and is further aggravated by human activities. Selenium is ubiquitous in the environment, and the two main sources of human exposure by Se are food and water. Se, a metalloid, is an important micronutrient due to Se antioxidant, anti-inflammatory and chemo-preventative properties. At normal dietary doses, selenium is an essential diet element that has nutritional proper-E. Lichtfouse (*)

“…Alternatively, the biomass can be treated with an iron (Fe) solution prior to conversion to biochar to produce a biosorbent that effectively binds metalloids [35][36][37]. The sequential application of biochar and Fe-treated biochar can then be used to comprehensively remove metals and metalloids from a range of industrial wastewaters [36].…”
