Plain English Summary
Researchers exposed guinea pigs to powerful electric fields (the kind found near high-voltage power lines) for 8 hours daily over three days to see if it would damage brain tissue through oxidative stress. They found no statistically significant effects on brain cell damage markers or antioxidant defenses, even at the highest exposure levels tested. While this suggests these particular electric field exposures may not cause measurable brain oxidative damage in the short term, the researchers noted some non-significant trends that warrant further investigation.
Study Details
The aim of this study was to evaluate the possible effects of varied exposure to 50 Hz extremely low frequency (ELF) electric field (EF) on the lipid peroxidation levels and antioxidant enzyme activities in the brain homogenates of guinea pigs. Subjects were exposed to 2 kV/m, 2.5 kV/m, 3 kV/m, 3.5 kV/m, 4 kV/m, 4.5 kV/m and 5 kV/m electric fields for three days, 8 h a day in both vertical and horizontal directions.

Although the study showed several positive but non-significant findings (p > 0.05), we did not find ...
The present study observed effects of 50 Hz EF exposure on lipid peroxidation levels and antioxidant defense mechanisms but these were not statistically significant at the 95% confidence level. Further research on the effects ELF-EF exposure on lipid peroxidation levels and antioxidant defence mechanisms are warranted.
