Summary

Welding exposure negatively impacts lung function and increases oxidative stress in workers, indicated by lower pulmonary function test results and altered oxidant-antioxidant markers. These findings highlight the need for protective measures against welding fumes and gases.

Area of Science:

  • Occupational Health
  • Pulmonary Medicine
  • Biochemistry

Background:

  • Welding processes emit hazardous by-products, including metal oxide particles in fumes.
  • Chronic exposure to welding fumes is linked to respiratory issues.
  • The impact on pulmonary function and oxidative stress requires further investigation.

Purpose of the Study:

  • To assess the effects of welding on pulmonary function.
  • To evaluate the oxidant-antioxidant status in welding workers.
  • To determine the association between welding and respiratory symptoms.

Main Methods:

  • Recruited 51 welding workers and 31 controls for interviews and spirometry.
  • Administered a respiratory illness questionnaire and collected demographic/work history.

  • Measured serum thiobarbituric acid reactive substances (TBARS), protein carbonyls, protein sulfhydryls (SH), and erythrocyte reduced glutathione (GSH).

    • Main Results:

    • Welding workers reported higher rates of coughing, sputtering, and wheezing.
    • Significantly lower pulmonary function (FEV1/FVC, FEF parameters) in welders.
    • Elevated serum TBARS and protein carbonyls, with decreased protein SH and GSH levels in welders.

    Conclusions:

    • Chronic welding exposure adversely affects pulmonary function and induces oxidative stress.
    • Welding work presents a significant risk for chronic bronchitis.
    • Implementing preventive measures is crucial for protecting welding workers' health.
