Abstract

Nanoparticles are increasingly used in many industrial sectors due to their unique properties, yet their introduction in ecosystems is of concern for health and food security. In particular, the accumulation of nanoparticles in soils may disturb the soil and plant system, possibly inducing a risk for crop production. Here, we review recent advances on nanoparticles in the soil–plant system. We focus on sources, emission, transformation, bioavailability, interactions, phytotoxicity and plant uptake of nanoparticles. We emphasize the genomic, metabolomic and proteomic alterations in plants caused by nanoparticles. Besides negative impacts, benefits of nanoparticles for plant growth are discussed.
