Description
Background: There is little information about the airborne hazardous agents released during the heat treatment when manufacturing a welding material. This study aimed to evaluate the airborne hazardous
agents generated at welding material manufacturing sites through area sampling.
Methods: concentration of airborne particles was measured using a scanning mobility particle sizer and optical particle sizer. Total suspended particles (TSP) and respirable dust samples were collected on
polyvinyl chloride filters and weighed to measure the mass concentrations. Volatile organic compounds and heavy metals were analyzed using a gas chromatography mass spectrometer and inductively coupled plasma mass spectrometer, respectively.
Results: The average mass concentration of TSP was 683.1 677.4 mg/m3 , with respirable dust accounting for 38.6% of the TSP. The average concentration of the airborne particles less than 10 mm in diameter was 11.2-22.8 104 particles/cm3 , and the average number of the particles with a diameter of 10e100 nm was approximately 78e86% of the total measured particles (<10 mm). In the case of volatile organic compounds, the heat treatment process concentration was significantly higher (p < 0.05) during combustion than during cooling. The airborne heavy metal concentrations differed depending on the materials used
for heat treatment. The content of heavy metals in the airborne particles was approximately 32.6%.
Conclusions: Nanoparticle exposure increased as the number of particles in the air around the heat treatment process increases, and the ratio of heavy metals in dust generated after the heat treatment
process is high, which may adversely affect workers’ health.
