| Abstract: | Objective]To characterize several carbon nanotubes(CNTs) and detect it toxicity effects on the respiratory system of mouse.Method]The transmission electron microscopy(TEM) and Raman spectroscopy were adopted to detect the characters of several sold CNTs;and then the effect of CNTs on the respiratory system of mouse was observed by AniRes-2005 after aerosolization administration.Result]The respiratory system of mouse was slightly affected by SWCNTs,but greatly influenced by MWCNTs.Conclusion]The effects of CNTs on the respiratory system of mouse related to the content of impurities and the diameter of nonotubes. |
