Influence of TiO2 agglomeration on THP-1 biological responses. Total glutathione (GSH) (a), IL-8 (b) and IL-1β secretion (c), and DNA damage (d) measured in cell cultures after 24 h exposure to different concentrations of small (SA) and large agglomerates (LA) of 17 nm TiO2. Data are expressed as means ± SD from three independent experiments performed in duplicates. p < 0.05 (*), p < 0.01 (**) and p < 0.001 (***) represent significant difference compared to control (One-way ANOVA followed by Dunnett’s multiple comparison test). Two-way ANOVA was used to determine the significant differences between suspensions (significant p value indicated at the top left corner)
