Cytotoxicity of nanoparticles of welding aerosols (data from literature and own research)

Abstract

The data of literature and own researches concerning features of toxic action of welding aerosols are generalized. Which have a different chemical composition and dimensions. Their damaging effect depends on many factors. Prolonged exposure may occur in low concentrations. Most of the negative effects are determined by oxidative stress and DNA damage. There are the most dangerous components of welding electrodes are chromium and nickel. Key words: welding aerosol, nanoparticles, cytotoxicity, damaging effect.
