Physical-chemical characterization and ecotoxicity of residues from alteration of engineered nanomaterials

Résumé : Little is known at present concerning impact of nanotechnologies on our environment, and especially the fate after degradation of nanocomposites included in nanomaterials, like sunscreen formulations released in water after use. This study focuses on the aging and behaviour of a mineral nanometric UV filter, TiO2 nanoparticle core coated with AlOOH and embedded in polydimethylsiloxane (PDMS). This nanocomposite was submitted to UV alteration in water, and the byproducts formed were characterized in terms of size, chemistry and physical-chemical properties. Finally, we also studied the potential toxic effects of this byproducts on fish (Danio rerio) and crustaceous (Daphnia magna).
