Micronuclei formation in Chinese hamster ovary CHO AA8, primary normal human epidermal keratinocytes neonatal (HEKn) and primary normal human dermal fibroblast FJ cells after 6 h’ treatment with kaolin micro- and nano-particles. Mean ± S.D. values of three independent experiments are shown. In the graph, CT represents the solvent control (treatment with 0.005% (v/v) Tween 80). Concentrations are given in μg/mL. MMC represents a positive control (0.1 μg/mL mitomycin C) treatment. *Significant difference versus the solvent control at p < 0.05, †significant difference between particle size at p < 0.05, according to the Tukey-Kramer method
