Abstract

Exposure to noise induce production of free radicals leading to increasing oxidative injury in whole body organs. This study involved ninety one workers aged (40.055 ± 11.56) years old, randomly selected from tow different gas electric stations compared with seventy apparently health persons as control group aged (38.366 ± 10.73) years old. Malondialdehyde MDA level, Triiodothyroid hormone T3 and Thyroxine hormone T4 were significantly (P≤0.05) higher in workers than that in the control, while Reduced glutathione GSH level and Acetylcholinesterase AChE activity were significantly (P≤0.05) lower in all groups of workers compared with control group, also Testosterone hormone level was significantly (P≤0.05) decreased in all groups of workers.

Keywords: Noise pollution, Acetylcholinesterase, Testosterone, Malondialdehyde MDA, Thyroid hormone, Glutathione GSH.
