| Title | Insights into the CuO nanoparticle ecotoxicity with suitable marine model species |
| Abstract | Metal oxide nanoparticles, among them copper oxide nanoparticles (CuO NPs), are widely used in different applications (e.g. batteries, gas sensors, superconductors, plastics and metallic coatings), increasing their potential release in the environment. In aquatic matrix, the behavior of CuO NPs may strongly change, depending on their surface charge and some physical-chemical characteristics of the medium (e.g. ionic strength, salinity, pH and natural organic matter content). Ecotoxicity of CuO NPs to aquatic organisms was mainly studied on freshwater species, few tests being performed on marine biota. |

In aquatic matrix, the behavior of CuO NPs may strongly change, depending on their surface charge and some physical chemical characteristics of the medium e.g. ionic strength, salinity, pH and natural organic matter content . Ecotoxicity of CuO NPs to aquatic organisms was mainly studied on freshwater species, few tests being performed on marine biota. The aim of this study was to assess the toxicity of CuO NPs on suitable indicator species, belonging to the ecologically relevant level of consumers. The selected bioassays use reference protocols to identify Effect/Lethal Concentrations E L C , by assessing lethal and sub lethal endpoints. Mortality tests were performed on rotifer Brachionus plicatilis , shrimp Anemia franciscana and copepod Tigriopus fulvus . While moult release failure and fertilization rate were studied, as sub lethal endpoints, on T. fulvus and sea urchin Paracentrotus lividus , respectively. The size distribution and sedimentation rates of CuO NPs, together with the copper dissolution, were also analyzed in the exposure media. 147 Published version Insights into the CuO nanoparticle ecotoxicity with suitable marine model species Rotini et al., 2018.pdf Articolo in rivista Elsevier etc. 0147 6513 Ecotoxicology and environmental safety Ecotoxicology and environmental safety Ecotoxicol. environ. saf.
