Abstract

Background: Welding in automobile manufacturing exposes workers to harmful fumes, impacting pulmonary function. This study examined changes in pulmonary function among welders. Methods: A retrospective cohort study was conducted on 1200 welders and 1200 administrative staff in the automotive industry from 2018 to 2022. Pulmonary function tests were performed according to ATS guidelines, and metal fume sampling for copper, iron, and lead was conducted in welders’ respiratory zones. Results: The mean concentrations of Cu, Pb, and Fe were 0.124, 0.117, and 1.42 mg/m3, respectively. Pb exceeded TLV-TWA. Welders showed significantly lower pulmonary function compared with the control group (P < 0.05). Conclusions: Prolonged exposure to welding fumes significantly reduces pulmonary function, necessitating preventive measures. © 2024 American College of Occupational and Environmental Medicine.
