英文摘要 | To assess the toxicity of copper nanoparticles (23.5 nm) in vivo, ld(50), morphological changes, pathological examinations and blood biochemical indexes of experimental mice are studied comparatively with micro-copper particles (17 mu m) and cupric ions (cucl(2)center dot 2h(2)o). the ld(50) for the nano-, micro-copper particles and cupric ions exposed to mice via oral gavage are 413, > 5000 and 110 mg/kg body weight, respectively. the toxicity classes of nano and ionic copper particles both are class 3 (moderately toxic), and micro-copper is class 5 (practically non-toxic) of hodge and sterner scale. kidney, liver and spleen are found to be target organs of nano-copper particles. nanoparticles induce gravely toxicological effects and heavy injuries on kidney. liver and spleen of experimental mice, but micro-copper particles do not, on mass basis. results indicate a gender dependent feature of nanotoxicity. several factors such as huge specific surface area, ultrahigh reactivity, exceeding consumption of h(+), etc. that likely cause the grave nanotoxicity observed in vivo are discussed.
