Effects of industrial noise on the blood levels of superoxide dismutase, glutathione peroxidase and malondialdehyde

Objective Effects of noise on free radical production and antioxidant defence mechanism were investigated. Methods Plasma malondialdehyde (MDA), erythrocyte superoxide dismutase (SOD) glutathione peroxidase (GSH-Px) and ferritin levels were measured in weavers who worked at noisy workplace. Results MDA, GSH-Px and SOD levels were significantly higher in weavers than that of the controls. There was no significant difference in ferritine levels. Conclusions These data suggest that employees who work at noisy workplace may be under the risk of free radical mediated damage in long time duration.
