dc.description.abstract | With the rapid development of the nano-industry, concerns about their potential adverse health effects have been raised. Thus, ranking accurately their toxicity and prioritizing for in vivo testing through in vitro toxicity test is needed. In this study, we used three types of synthesized aluminum oxide nanoparticles (AlONPs): gamma-aluminum oxide hydroxide nanoparticles (gamma-AlOHNPs), gamma- and alpha-AlONPs. All three AlONPs were spherical, and the surface area was the greatest for gamma-AlONPs, followed by the alpha-AlONPs and gamma-AlOHNPs. In mice, gamma-AlOHNPs accumulated the most 24 h after a single oral dose. Additionally, the decreased number of white blood cells (WBC), the increased ratio of neutrophils and the enhanced secretion of interleukin (IL)-8 were observed in the blood of mice dosed with gamma-AlOHNPs (10 mg kg(-1)). We also compared their toxicity using four different in vitro test methods using six cell lines, which were derived from their potential target organs, BEAS-2B (lung), Chang (liver), HACAT (skin), H9C2 (heart), T98G (brain) and HEK-293 (kidney). The results showed gamma-AlOHNPs induced the greatest toxicity. Moreover, separation of particles was observed in a transmission electron microscope (TEM) image of cells treated with gamma-AlOHNPs, but not gamma-AlONPs or alpha-AlONPs. In conclusion, our results suggest that the accumulation and toxicity of AlONPs are stronger in gamma-AlOHNPs compared with gamma-AlONPs and alpha-AlONPs owing their low stability within biological system, and the presence of hydroxyl group may be an important factor in determining the distribution and toxicity of spherical AlONPs.
