Opis:: Workers at metal machining workstations are exposed to airborne dust particles containing metals and their compounds. Their harmful impact on the workers’ health depends on both their chemical composition and their distribution. The aim of this study was to determine the content of metals in dust fractions emitted in the process of mechanical machining of products made of brass, steel and cast iron. Samples taken during grinding, turning and drilling were tested. The concentration of metals in dust fractions was determined with atomic absorption spectrometry. The content of iron, manganese, chromium, zinc, lead, copper and nickel in the dust fractions was highly differentiated depending on the size of the particles, the material and the processes used.

Opis:: This article discusses the idea and set-up of a laboratory system for generating reproducible concentrated occupational aerosols containing metal compounds. Dust representatives for 2 metal-machining workstations (an electric grinder and an electric disc cutter) were released from a fluidized-bed generator, and then sampled and compared in respect to concentration, particle size distribution, particle morphology and the content of metal elements (Fe, Al, Cu, Mn, Cr, Ni, Pb, Zn, Mg). The results indicate the presence of a significant number of irregularly-shaped respirable particles. Those particles contained mainly Fe and Al, and their composition was shown to depend on particle size. The proposed system of aerosol generation and collection can be used in studies of interactions between airborne particles and a model lung surfactant.
