Abstract

Overview

The study examines the impact of various magnetic fields (MFs), specifically 6-mT at frequencies of 0, 50, and 120 Hz, on cellular ATP levels across 11 different cell lines. ATP is crucial as it powers nearly all cellular activities.

Findings

  • The 6-mT static magnetic field (SMF) did not significantly alter or it increased cellular ATP levels.
  • By contrast, 6-mT 50-Hz MFs showed no change or a decrease in ATP levels.
  • 6-mT 120-Hz MFs exhibited variable effects on the ATP levels.
  • Investigations into mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) across four cell lines showed no direct correlation with ATP changes.

Conclusion

Although changes in ATP levels induced by different MF frequencies were not dramatic, the variability suggests that effects are dependent on cell type, MF frequency, and duration of exposure. Understanding these interactions is imperative because of the widespread human exposure to MFs through everyday sources like power lines and household appliances.
