Toxicity of welding aerosol signifi cantly aff ects the choice of the type of electrodes for arc welding. Modern research methods allow determining the content of divalent and trivalent manganese particles in the solid component of welding aerosol. The studies were carried out to determine the ability of detecting the presence of ions of the most toxic tetravalent manganese in the solid component of welding aerosol. The possibility of using the method of RFS analysis for fi xing manganese ions in the Mn4 + state in welding aerosols is shown. 9 Ref., 3 Tabl., 2 Fig.
