•Different toxicity observed on different CeO2 nanostructured samples.•Nanostructure compositions and interactions with cells are likely the causes.•Toxicity tests on bacteria only may not be suitable for predicting the ecotoxicity. Conflicting reports on the toxicity of CeO2 nanomaterials have been...
