Research by TOPLUS suggests that the nano cerium oxide is toxic to humans.
Harm of nano cerium oxide: cerium oxide rare earth element salt can reduce the content of prothrombin, make it inactivated, and inhibit the production of thrombin, make fibrinogen precipitate, catalyze the decomposition of phosphate compounds, the toxicity of rare earth elements decreases with the increase of atomic weight.Inhalation contains cerium dust, occupational pneumoconiosis, its chloride damage to the skin, can stimulate the mucous membrane of the eyes.Maximum permissible concentration: cerium oxide 5 mg/m3, cerium hydroxide 5 mg/m3, should wear a respirator when working, if there is radioactivity to carry out special protection, dust should be prevented from scattering.
