文摘

Phytotoxicity is influenced by several factors, including but not limited to NP size, shape, coating, use of carrier, genotypes and experimental methods. Silver and titanium dioxide nanoparticles both affect germination, growth and photosynthetic efficiency in multiple ways, inducing oxidative stress, cytotoxicity and/or genotoxicity. AgNPs appear to exhibit more toxic effects in multiple species, whereas TiO2NPs show some beneficial effects as well. In view of rapidly increasing applications of engineered nanomaterials, it is necessary to carry out toxicity studies at organismal and ecosystem levels. In vitro studies do not appropriately reflect effects at the whole organism-level.
