Abstract

Abstract Summary

Overview

Extremely low frequency electromagnetic fields (ELF EMFs) generated by overhead powerlines are known to have biological impacts on multiple species.

Findings

  • Honey bees, crucial for global pollination, are frequently exposed to ELF EMFs during their flights near powerlines.
  • Study investigates how acute exposure to 50 Hz ELF EMFs, within a range of 20-100 µT at ground level and 1000-7000 µT closer to powerline conductors, affects bees.
  • Significant effects included:
    • Reduced learning capacity.
    • Altered flight dynamics.
    • Decreased success of foraging flights.
    • Reduced feeding activity.

Conclusion

Based on the study, 50 Hz ELF EMFs emitted by powerlines could pose a serious environmental challenge to honey bees. This impact could extend to their cognitive and motor functions, potentially diminishing their role in pollination.
