Abandoned Mine Lands Reclamation by Plant Remediation Technologies

Abandoned mine lands (AMLs), which are considered some of the most dangerous anthropogenic activities in world, a source hazards relating to potentially toxic elements (PTEs). Traditional reclamation techniques, expensive, time-consuming and not well accepted by general public, cannot be used on large scale. However, plant-based techniques have gained acceptance as an environmentally friendly alternative over last 20 years. Plants can AMLs for PTE phytoextraction, phytostabilization, phytovolatilization. We reviewed these phytoremediation paying particular attention selection appropriate plants each case. In order assess suitability purposes, accumulation capacity tolerance mechanisms PTEs was described. also compiled collection interesting actual examples AML phytoremediation. On-site studies shown positive results terms soil quality improvement, reduced bioavailability, increased biodiversity. strategies need better characterize potential plant candidates improve extraction reduce negative impact AMLs.
