Abstract

Overview

The study examines the direct and transgenerational impact of radio frequency electromagnetic fields (RF-EMF) on Daphnia magna, a model organism for crustaceans.

Materials and Methods

• Subjects: D. magna chronically exposed to 900 GHz EMF with an energy flux density of approximately 1 mW/cm².
• Exposure Period: Occurred during the juvenile and pubertal periods of their ontogenesis.

Findings

Our findings indicate a significant impact on the fertility and size of the irradiated daphnids and their first-generation offspring due to exposure to RF-EMF.

• Decreased fertility correlated with cytotoxic effects on animal cells.
• Reduction in spike and body size of the crustaceans reflects the adverse radiation effects on the population's protective strategies.

Conclusion

Reproductive processes showed restoration by the second generation, providing insights into potential in vivo mechanisms underlying RF-EMF effects. The implications of these findings stress the importance of considering electromagnetic field hazards in environmental and health safety assessments.
