Environmental impact of sunscreen nanomaterials: Ecotoxicity and genotoxicity of altered TiO2 nanocomposites on Vicia faba

► TiO2-containing sunscreen nanocomposites were artificially aged. ► Vicia faba was exposed 48 h to the alteration byproducts in liquid phase. ► Few endpoints were modified significantly from control. ► A clogging on the roots and titanium penetration in tissues were suspected. ► Eventual long-term effects of the particles may occur.
