Abstract
The brine shrimp,Artemia spp., is widely used in ecotoxicological research as a biological index. In the present study, aquatic stability and acute toxic effects of TiO2, CuO and ZnO nanoparticles (NPs) onArtemia franciscana were investigated.Acute exposure was conducted in sea water with different concentrations of selected nanoparticles at 24h, 48h, 72h and 96h. The mortality rate ofA. francisca increased significantly with increasing concentrations and duration of exposure of all NPs. The toxicity pattern of metal oxides toA. francisscana was as follows: CuO>TiO2>ZnO. Our results point to the fact that both TiO2 and ZnO NPs exhibited moderate toxicity toArtemia larvae in 24h as compared with CuO, regardless of their size and concentrations.
Keywords: Acute toxicity,Artemia franciscana,Titanium dioxide, Copper oxide, Zinc oxide.
