Assisted Phytoremediation of Trace Toxic Elements (TTE): The Role of Vermicompost
摘要
Several anthropogenic activities, such as the use of pesticides, hazardous chemicals, industrial effluents, and metals, cause environmental pollution. The health of plants, animals, and people is seriously threatened by pollution, which affects both aquatic and terrestrial environments. The conventional methods for cleaning up contaminants from soil and water are seen to be ineffective, costly, and detrimental to the environment. The effect of trace toxic elements (TTE) can be mitigated by a process referred to as phytoremediation. It involves the use of green plants to remove pollutants such as trace toxic elements from contaminated sites, and the method is also used to eliminate toxins from the environment. Phytoremediation, which is environmentally friendly could be difficult to achieve many a times because of the level of pollutions in the surrounding environment. Therefore, plants could be assisted by products like vermicast. Vermicasts are produced from vermicomposting process which involves the use of earthworms in degrading organic substances and turning them into useful products. The accumulation and tolerance capacities of plants used in phytoremediation can be greatly improved with advancements in vermicomposting. This paper reviews phytoremediation techniques for TTE with consideration of vermicompost in an assisted capacity.
