Abstract

Overview

This study investigates the effects of low-frequency magnetic fields (MF) on the embryonic development of Japanese quail. With increasing concerns over magnetic pollution from electrical devices, this research utilizes bird embryos to assess potential health risks associated with electromagnetic fields (EMF).

Method and Exposure Details

  • Species: Japanese quail (Coturnix japonica).
  • Magnetic Field Exposure: 60 Hz at intensities of 0.16 mT and 0.65 mT.
  • Sample Size: 30 eggs were divided into three groups: control, 0.16 mT exposure, and 0.65 mT exposure.
  • Assessment Techniques: Morphometric evaluations of embryos and fractal analysis of the yolk sac membrane vascular networks.

Findings

The study found no significant differences in the fractal dimensions of the vascular networks or the embryonic body mass among the different groups. However, it was noted that the embryos exposed to the higher intensity of 0.65 mT showed a reduction in overall body development, specifically in body area and cephalic length.

Conclusion

Exposure to magnetic fields of 0.16 mT and 0.65 mT did not lead to significant changes in vasculogenesis and angiogenesis. Yet, the observed decrease in body development at 0.65 mT intensity suggests potential underlying risks associated with prolonged exposure to EMFs at certain intensities, highlighting the need for further research into the biological impacts of magnetic fields.
