| Abstract: | The growing application of engineered nanomaterials is leading to an increased occurrence of nanoparticles (NPs) in the environment. Thus, there is a need to better understand their potential impact on the environment. This study evaluated the toxicity of nanosized TiO2, ZrO2, Fe0, Fe2O3, and Mn2O3 towards the yeast Saccharomyces cerevisiae based on O2 consumption and cell membrane integrity. In addition, the state of dispersion of the nanoparticles in the bioassay medium was characterized. |
