Soil Pollution and Remediation
This chapter is in the book Soil Pollution and Remediation

Abstract

A strategic plan for plant succession is necessary for rehabilitating areas impacted by mining activities. The plan should include the integration of rapidly growing grass species, leguminous plants, and various grasses and shrubs to establish ground cover, stabilize the surface, and maintain continuous vegetative coverage. The selection of suitable plant species for remediation and revegetation should prioritize their capacity to accumulate and transport pollutants, detoxify or immobilize pollutants, generate substantial biomass, withstand toxic pollutant levels, and exhibit rapid growth and a short life cycle. A variety of plant life including grasses, legumes, shrubs, and trees is suggested for long-term remediation efforts. Trees are often chosen for large-scale land decontamination and revegetation because they have the capacity to produce biomass, reach deep into the soil, aid in nutrient cycling, and access nutrients and contaminants in lower soil layers. Caution is advised when utilizing specific tree species, like Eucalyptus, due to potential adverse impacts on plant species and biodiversity. Genetically modified plants for phytoremediation and monoculture are subjects of contention.
