Composition of Metallic Elements and Size Distribution of Fine and Ultrafine Particles in a Steelmaking Factory
Background: The characteristics of aerosol, in particular particle size and chemical
composition, can have an impact on human health. Particle size distribution and chemical
composition is a necessary parameter in occupational exposure assessment conducted in order
to understand possible health effects. The aim of this study was to characterize workplace airborne
particulate matter in a metallurgical setting by synergistically using two different approaches;
Methodology: Analysis of inhalable fraction concentrations through traditional sampling equipment
and ultrafine particles (UFP) concentrations and size distribution was conducted by an Electric
Low-Pressure Impactor (ELPI+â„¢). The determination of metallic elements (ME) in particles was
carried out by inductively coupled plasma mass spectrometry; Results: Inhalable fraction and ME
concentrations were below the limits set by Italian legislation and the American Conference of
Governmental Industrial Hygienists (ACGIH, 2017). The median of UFP was between 4.00 104
and 2.92 105 particles/cm3. ME concentrations determined in the particles collected by ELPI show
differences in size range distribution; Conclusions: The adopted synergistic approach enabled a
qualitative and quantitative assessment of the particles in steelmaking factories. The results could
lead to a better knowledge of occupational exposure characterization, in turn affording a better
understanding of occupational health issues due to metal fumes exposure
