Abstract

Overview

The study investigates the impact of electromagnetic radiation (EMR) emitted from common electronic devices on Allium cepa L. over one week.

Findings

  • EMR Exposure: The plant was exposed to EMR at frequencies of 1800 MHz and 2400 MHz, with power levels at 10.0 dBm across varying exposure durations from 1 to 8 hours per day.
  • Morphological Effects: Decreases in root length, fresh weight, and dry weight were noted with increased exposure.
  • Biochemical Changes: A reduction in protein content and significant changes in antioxidative enzyme activities (APX, GR, GST, DHAR, CAT, SOD, and POD) were observed, especially during 6 and 8 hours of daily exposure.
  • Genotoxicity: Chromosomal aberrations were induced in the root tip cells, indicating genotoxic effects.

Conclusion

This research illustrates the potential adverse effects of prolonged EMR exposure on plant health, emphasizing the need for further studies into the environmental impacts of electromagnetic pollution.
