Summary: | Engineered Nanomaterials (ENMs) are revolutionizing our daily
lives, industry, and agriculture. Along with their novel applications,
major concerns have emerged due to the potential toxicity
to biological systems. Since soils are considered the main
destination for ENMs, research focused on their interaction with
plants is gaining more attention, especially at the physiological
and biochemical levels. This review addresses the capacity of
some plants to accumulate ENMs or released ions, highlighting
the beneficial and detrimental effects and the potential use of
some plants to remediate ENM-contaminated environments.
Although the uptake process depends on multiple factors, the
literature suggests that concentrations <50 mg/kg are beneficial,
while higher doses negatively impact physiological and
biochemical parameters. However, the current data does not
allow the formulation of mechanistic model effects. Finally, this
review remarks on the pivotal role played by plants as a sustainable
alternative to face the environmental buildup of ENMs
and to guarantee food security. |
