TL;DR: The results suggest that both CNTs and GNFs are genotoxic in human bronchial epithelial BEAS 2B cells in vitro, and this activity may be due to the fibrous nature of these carbon nanomaterials with a possible contribution by catalyst metals present in the materials.

TL;DR: The studies in human bronchial epithelial BEAS 2B cells showed that uncoated nanosized anatase TiO2 and fine rutileTiO2 are more efficient than SiO 2-coated Nanosized rutiles TiO 2 in inducing DNA damage, whereas only nanosize anatase is able to slightly induce micronuclei.

TL;DR: Interestingly, the level of lung inflammation could not be explained by the surface area of the particles, their primary or agglomerate particle size, or radical formation capacity but is rather explained byThe surface coating.

TL;DR: Results show that nanosized CNC is neither genotoxic nor immunotoxic under the conditions tested, whereas non‐nanosized MCC is able to induce an inflammatory response.

TL;DR: In this article, the effects of storage conditions such as relative humidity and physical loading on the dustiness of five inorganic metal oxide nanostructured powder materials were investigated using a down-scaled EN15051 rotating drum.
