Abstract
The aim of this study was to examine effects of lead (Pb)-based paints on malondialdehyde (MDA) levels as an indicator for lipid peroxidation; and on activities of serum antioxidant enzymes activities such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) in industrial painters. A total of 67 male painters and 50 age-matched and gender-matched controls were included in this cross-sectional study. There were 19 smokers and 48 non-smokers in the paint-exposed group and 20 smokers and 30 non-smokers in the control group. Hemoglobin concentrations were lower in painters’ blood compared to controls. The blood Pb concentrations were higher in painters compared to controls. SOD and GPx activities were significantly lower in painters compared to controls. MDA concentration was found to be significantly elevated. Smoking was found to be a major confounder. Data suggest that Pb-based paints affect oxidant parameters in occupationally exposed workers.
