Results obtained in evaluation of parameters characterizing nano-particles in air of titanium production workplace
To reveal, identify and evaluate nano-particles content, the authors performed screening studies of nano-particles in the air of workplace contaminated with aerosol coming from high-temperature titanium smelting. The studies involved diffuse spectrometry, scanning electronic microscopy, energy dispersion analysis, mass spectrometry with inductively coupled plasma. Objects identified are nano-particles with average aerodynamic diameter ranging 35.5 — 71 nm, mostly rounded shape, chemically close to titanium oxide, counted concentration of them varied from 86 to 360 billion particles per cubic meter.
