Zebrafish Larval Melanophores Respond to Electromagnetic Fields Exposure

Abstract

Overview

Groups of zebrafish (Danio rerio) embryos were subject to a study investigating the impact of electromagnetic fields of varying frequencies and intensities. These experiments utilized new prototype devices designed to administer static and dynamic electromagnetic fields.

Experimental Design

• Exposure to frequencies: static (0 Hz), extremely low-frequency (0.2 Hz), low-frequency (270 kHz), very-high-frequency (100 MHz), and ultra-high-frequency (900 MHz).
• Magnetic intensities: 40 mT at 0 Hz and 0.2 Hz, 470 μT at 270 kHz, 240 nT at 100 MHz and 900 MHz.
• The study included control groups comprising unexposed embryos to compare changes.

Findings

The exposure to these varied radiations led to noticeable alterations in the body pigmentation of zebrafish embryos and larvae, impacting the number, area, and morphology of melanophores.

Conclusion

This research underscores the significant effects of magnetic radiation on biological entities, enhancing our understanding of its potential health impacts on living organisms. Such insights are pivotal for assessing the safety and risks associated with electromagnetic field exposure.
