The aim of this review is to analyze the literature data on the impact of dispersive and chemical composition of welding aerosols on their toxicity for the further development of measures and means of protection of respiratory organs of welders. It is shown that the total toxic effect of welding aerosols depends on their chemical composition and the size of aerosol particles. Nanoparticles of welding aerosols can have completely different physicochemical properties and biological effects compared to substances in the normal physicochemical state. They belong to harmful substances with an increased potential risk to human health. Welding aerosols, getting into the body of the welder, cause toxic effects, resulting in various diseases of respiratory organs, nervous and circulatory systems, cancer diseases. Since it is impossible to completely remove welding aerosol from the welding zone, it is necessary to continue the study of their chemical and dispersed composition, levels of emissions and methods of reducing toxic effects. In the process of welding, the elements contained in welding materials are transferred in aerosol. Therefore, it is necessary to study the factors affecting an increase in the intensity of emissions and toxicity of welding aerosols. 41 Ref., 2 Tabl., 1 Fig. [ABSTRACT FROM AUTHOR] |
