Abstract
Phytoremediation is currently an area of trending research due to its huge potential as a sustainable substitute for traditional methods of restoring contaminated sites. It is a profitable and ecological alternative to mechanical and chemical remediation techniques used worldwide. An increase in soil, water, and air pollution has severely disturbed an ecosystem functions and poses a huge threat to the natural and agricultural environment as well as public health. Remediation of the contaminated environment is one of the paramount concerns of the world. Hence this article deliberates on the general problems of pollutants linked to phytoremediation techniques of organic and inorganic contaminants, especially agrochemicals, petroleum, and explosive compounds. The paper also reviews a systematic assessment of the recent progress in the phytoremediation of contaminants in a natural and agricultural environment. Additionally, we highlight the benefits and limitations of phytoremediation along with a brief clarification of the resilient mechanistic removal of contaminants by a three-phase method. Finally, the perspective of biotechnological approaches in remediation is also suggested; taking into consideration the future of synergistic remediation approaches and genetically improved plants to enhance phytoremediation.
