Abstract

Overview

This study investigates the impact of various electromagnetic fields on zebrafish embryos, employing a range of radiations with different frequencies and intensities.

Methodology

Zebrafish (Danio rerio) embryos are subjected to specific radiation frequencies through new prototype devices. The frequencies tested are:

  • Static (B0, 0 Hz)
  • Extremely low-frequency (ELF, 0.2 Hz)
  • Low-frequency (LF, 270 kHz)
  • Very-high-frequency (VHF, 100 MHz)
  • Ultra-high-frequency (UHF, 900 MHz)

Applied magnetic field intensities are as follows:

  • 40 mT at 0 Hz
  • 40 mT at 0.2 Hz
  • 470 μT at 270 kHz
  • 240 nT at 100 MHz
  • 240 nT at 900 MHz

Findings

Exposed zebrafish display significant changes in body pigmentation compared to the control group. Specific changes include the total number, area, and morphology of the black pigment cells known as melanophores.

Conclusion

This research contributes to our understanding of how different electromagnetic fields can potentially impact living organisms, particularly in terms of morphological changes in pigment cells.
