Phytoremediation Technique for Pesticide-Contaminated Environments as a Green and Eco-Friendly Approach: A Review

Phytoremediation, or bioremediation, is the use of plants and their rhizosphere's microorganisms to contain, remove, transform, or detoxify pollutants in soil, water, or air. This eco-friendly method has become a very effective strategy for addressing pesticide contamination, one of the major global environmental issues, and has even been proven in scientific circles. The review's main purpose is to present phytoremediation in detail to the world as a sustainable, environmentally friendly technology for the cleanup of pesticide-contaminated soils. The review integrates the latest information on bioremediating plants and, at the same time, emphasizes recent developments in different plant species proficient at accumulating or degrading pesticide residues. Among the major phytoremediation mechanisms are phytoextraction, wherein the contaminants are taken up and stored in the plant parts that can be easily collected; phytodegradation, which is the process of breaking down the pollutants by plants and their associated microorganisms' metabolic activities; phytostabilization, preventing the contamination spread and the toxins being taken up by living organisms in soils and sediments; phytovolatilization, the conversion of the less toxic forms of the pollutants and their release into the atmosphere; and rhizofiltration, the practice whereby the roots of the plants act as filters to remove contaminants from the water supplying them. Together, the above-stated mechanisms play a significant role in reducing the toxicity of pesticides and their persistence in the environment. The review points out the pros and cons of efficiency between phytoremediation and conventional methods, the latter often being very expensive, energy-intensive, and environmentally damaging. In conclusion, phytoremediation is a cost-effective, environmentally friendly option for large-scale pesticide cleanup, helping nature recover and protecting the environment for the long term.
