Introduction: The effect of prolonged exposure to welding fumes on blood levels remains an unresolved question. In our study, we aimed to determine the effects of metal fume exposure on various blood parameters in welders. Materials and Methods: The study was cross-sectional. It included all male welding workers admitted to a health institution, a reference hospital for occupational diseases, for 2021. It was conducted with 254 individuals. The variables examined included age, duration of employment, smoking habit, body mass index, hemoglobin levels, erythrocyte, leukocyte and platelet counts, aspartate aminotransferase, alanine aminotransferase, free prostate-specific antigen, creatinine and manganese levels, and erythrocyte sedimentation rates. Results: In our study, 40.6% of the welders were between 21-30 years old. 65.7% of the participants have been welding for more than five years. According to body-mass index values, 44.1% of the participants were pre-obese, and 16.9% were obese. 63.8% of the participants were smokers. In 35.8% of participants, hyperglycemia was present, and polycythemia was present in 27.2%. When blood parameters were analyzed, fasting blood glucose, aspartate transaminase, alanine transaminase, and sedimentation rate were lower in those who worked less than five years than those who worked five years or more. The difference was statistically significant. In blood test results, leukocyte, glucose, aspartate transaminase, alanine transaminase, and sedimentation rate values in welders were correlated with total working time. Conclusion: Welders in our study had a high prevalence of smoking, overweight, and obesity. Working time is correlated with liver enzyme levels and fasting blood glucose values. For healthier workers, employers should fulfill their responsibilities for occupational health and safety.
