Title Effect of extremely low frequency magnetic field on antioxidant activity in plasma and red blood cells in spot welders
Bibliographic information Jan. 2009, Vol.82, No.2, p.259-266. Illus. 20 ref.
Abstract The purpose of this study was to determine a possible relation between exposure to extremely low frequency magnetic fields (ELF-MFs) and human antioxidant activity. The total serum antioxidant status (TAS), and glutathione peroxidase (GPX) and superoxide dismutase (SOD) activity in red blood cells were measured in 46 spot welders who were occupationally exposed to ELF-MFs. The results were compared with those of a non-exposed control group. The correlation between magnetic field strength and antioxidant activity in red blood cells and plasma was then assessed. No significant differences in TAS levels were observed. However, in red blood cells of the exposed group, there were significant decreases in SOD and GPX activities. Furthermore, a significant negative correlation between SOD/GPX activities and magnetic field intensity was observed. The results indicate that ELF-MF could influence the red blood cell antioxidant activity and might act as an oxidative stressor.
