Despite high-tech nanoproducts have gained importance in the last decades, there is a lack of regulation in terms of the amounts of production and release into environments, whereas the final sinks are the water bodies that already suffer from other pollutants such as metals. As silica nanoparticles (SiNP) are one of the most produced and applied nanomaterial worldwide, we aimed to assess SiNP ecotoxicity, alone and in combination with an environmentally relevant concentration of Cu in Gambusia holbrooki freshwater fish. We exposed adult females to 0 (control), 10, and 100 mg SiNP/L (Sigma®,
