Phytoremediation of Contaminated Tannery Wasteland Soil with Metal-Tolerant Plants: A Literature Review
Suvashree Basu, Suchhanda Ghosh, Poornima Sharma
Abstract: Tannery wastelands are often contaminated with toxic heavy metals, posing significant environmental and health risks. Phytoremediation, a cost - effective and eco - friendly remediation approach, utilizes metal - tolerant plants to remove, stabilize, and degrade contaminants. This review explores the extent of heavy metal contamination in tannery soils and the mechanisms underlying phytoremediation, including phytoextraction, phytostabilization, and rhizofiltration. A range of metal - tolerant plant species such as Ricinus communis, Brassica juncea, Lantana camara, Gotalaria juncea, Parthenium hysterophorus, Hyptis suaveolense, Solanum nigrum, Cymbopogon flexuosus, Phragmites australis and Vetiveria zizanioides have demonstrated potential in remediating tannery - contaminated soils. However, phytoremediation faces challenges related to slow remediation rates, metal bioavailability, and biomass disposal. Future research should focus on enhancing remediation efficiency through genetic engineering, microbial - assisted approaches, and soil amendments. Integrating phytoremediation with sustainable land management practices can further improve its effectiveness. This study highlights the importance of phytoremediation in restoring degraded tannery sites and promoting environmental sustainability.
