Plant-assisted metal remediation in mine-degraded land: a scientometric review
2022
Bandyopadhyay, S.
Presently, the progressive concern for the adverse effect of mining has emphasized the significance of reclamation in derelict mine site. The manuscript aims to present a scientometric analysis followed by a review on eco-restoration of heavy metal polluted mine spoil, tailing and to develop a timeline analysis done in the last 10 years (2010–2020). Web of Science (WoS) database was used to obtain the desired data set, and these are analysed based on WoS categories, leading journals and contributing countries. According to these databases, research progress was delineated to draw a clear picture of the scientific status and progress and to develop knowledge gap in this area. China is the leading country in eco-restoration-based study for heavy metal remediation in mines. Among the categories, “Environmental Science” has the highest number of publications in this domain. After reviewing various literature, it is evident that vegetation cover has the ability to remediate mine derelict sites. Most of the studies reported that woody, fast growing, native vegetation cover suit best for heavy metal remediation. The use of vegetation cover native to the mining sites should be prioritized as they are better indicator of reclamation success due to their high biomass, fast growing, ability to acclimatize in adverse environmental condition in nature. Lastly, as most studies focused on the recuperating soil properties, the application of innovative genomic approaches (recognising genetic markers for abatement of contaminants) to heavy metal remediation practice should also be amplified to develop new concepts of land reclamation in mining area.
