description: The aim of this study was to investigate the possible impact of silver nanoparticles (Ag-NPs) on reproduction and development of different model organisms, such as sea urchins, barnacles, brine shrimps and zebrafish. In vivo toxicological tests were performed; the biological models were exposed to serial dilutions of commercial Ag-NPs. Our findings revealed that: i) all tests were suitable to verify the impact of Ag-NPs on models in term of exposure; ii) all tests can provide an idea of the role of NPs on environmental health; iii) an integrated interdisciplinary approach, using several model organisms, is recommended in order to have an overview of the effects of NPs on water environment.
description: Le but de cette étude était d'étudier le possible impact des nanoparticules d'argent (Ag-NP) sur la reproduction et le développement des différents modèles des organismes, tels que les oursins, les balanes, les crevettes de saumure et le poisson zèbre. Des tests toxicologiques ont été réalisées in vivo, les modèles biologiques ont été exposés à des dilutions successives de Ag- NP commerciale. Nos résultats ont révélé que: i) tous les tests ont permis de vérifier l'impact de l'Ag-IP sur des modèles en terme d'exposition, ii) tous les tests ont donné une idée du rôle des IP sur la santé de l'environnement; iii) une approche intégrée et interdisciplinaire, utilisant plusieurs des organismes modèles, est recommandé afin d'avoir un aperçu des effets des NP sur l'environnement aquatique.
description: Lo scopo di questo lavoro è stato valutare l’impatto delle nanoparticelle di argento (Ag-NPs) sulla riproduzione e sullo sviluppo di vari organismi modello, quali Paracentrotus lividus, Amphibalanus amphitrite, Artemia salina e Danio rerio. Sono stati eseguiti test tossicologici mediante esposizione in vivo; i modelli sono stati esposti a diluizioni seriali di Ag-NPs commerciali. I risultati hanno dimostrato che: i) i test utilizzati sono adatti a verificare l’impatto delle Ag-NPs sui modelli a seconda delle esposizioni; ii) l’impatto sugli organismi e, quindi sulla salute ambientale, è dose e tempo-dipendente; iii) l’approccio integrato tra diversi modelli permette una valutazione predittiva dell’impatto delle nanoparticelle sull’ambiente acquatico.
