Exposure to 2100 MHz electromagnetic field radiations induces reactive oxygen species generation in roots.

Abstract

During the last few decades there has been an enormous increase in the usage of cell phones as these are one of the most convenient gadgets and provide excellent mode of communication without evoking any hindrance to movement. However, these are significantly adding to the electromagnetic field radiations (EMF-r) in the environment and thus, are required to be analysed for their impacts on living beings. The present study investigated the role of cell phone EMF-r in inciting oxidative damage in onion () roots at a frequency of 2100 MHz. Onion roots were exposed to continuous wave homogenous EMF-r for 1, 2 and 4 h for single day and generation of reactive oxygen species (ROS) in terms of malondialdehyde (MDA), hydrogen peroxide (HO and superoxide anion (O) content and changes in the activities of antioxidant enzymes- superoxide dismutases (SOD) and catalases (CAT) were measured. The results showed that EMF-r exposure enhanced the content of MDA, HO and O. Also, there was an upregulation in the activity of antioxidant enzymes- SOD and CAT- in onion roots. The study concluded that 2100 MHz cell phone EMF-r incite oxidative damage in onion roots by altering the oxidative metabolism.

Main findings

Onion roots exposed to continuous wave homogeneous 2100 MHz EMF-r for 1, 2, or 4 hours showed increased MDA, hydrogen peroxide, and superoxide anion content. Activities of antioxidant enzymes SOD and CAT were upregulated, and the authors conclude the exposure induced oxidative damage by altering oxidative metabolism.

Outcomes measured

• Reactive oxygen species (ROS) markers
• Malondialdehyde (MDA)
• Hydrogen peroxide (H2O2)
• Superoxide anion (O2−)
• Antioxidant enzyme activity (SOD, CAT)

Limitations

• Sample size not reported in abstract
• Specific exposure metrics beyond frequency (e.g., SAR, power density) not reported in abstract
• Single-day exposure only (1–4 h)
