ABSTRACT
Soil pollution is a major environmental issue that has received worldwide attention. For treating contaminated soil, phytoremediation is a good and widely acknowledged approach. Several studies have been conducted to improve phytoremediation efficiency using various methods. The advancement of nanotechnology has provided a viable alternative. The use of nanomaterials to aid phytoremediation of contaminated soil is discussed in this chapter. Nanomaterials can help in phytoremediation by eliminating pollutants directly, enhancing pollutant phytoavailability, and boosting medicinal plant growth. For remediating contaminated soil, phytoextraction is one of the most effective and well-known phytoremediation approaches. Because of its excellent technical applications in treating contaminated soil and groundwater, microbial-mediated nanoparticles are the most effective nanomaterials for aiding phytoremediation. In general, utilizing the nanomaterials to aid phytoremediation of contaminated soil is a promising method, but it is still in its early stages of development. More application cases are needed, and study into the long-term efficacy of nanomaterials in phytoremediation systems is needed.
