摘要：
The present invention relates to an inhalation toxicity testing chamber device for nanoparticles having a plurality of concentrations. The present invention provides an inhalation toxicity testing chamber device for nanoparticles having a plurality of concentrations, which: can supply nanoparticles having different concentrations to particle exposure modules by stacking a plurality of particle exposure modules inside a single chamber housing and by allowing each particle exposure module so as to form an independent space from each other； can perform inhalation toxicity testing of nanoparticles having a plurality of concentrations through a single chamber housing by being capable of exposing the test animals put into each particle exposure module to nanoparticles having different concentrations； can easily perform inhalation toxicity tests of nanoparticles in a small scale laboratory etc. by improving the overall space efficiency as well as reducing the test cost； and can easily perform more diverse and accurate inhalation toxicity tests on nanoparticles by selectively allowing a plurality of particle exposure modules to be in communication with each other or to be formed as an independent space, according to a user's needs, thereby variably applying the space of the particle exposure module without changing the arrangement of the particle exposure module.
