Abstract

Overview

The study focused on the impacts of electromagnetic fields (EMF) on marine organisms, specifically the polychaete Hediste diversicolor. The EMFs tested were those typically found near submarine cables.

Findings

  • The EMF exposure was at 50 Hz and 1 mT.
  • No avoidance or attraction was observed in the behavior of H. diversicolor.
  • Enhanced burrowing activity was noted, suggesting a potential increase in bioturbation.
  • The energy balance remained positive, and a substantial portion (85%) of energy was available for growth after EMF exposure.
  • While food consumption and respiration rates remained unchanged, a significant decrease in ammonia excretion was documented.

Conclusion

This preliminary research indicates potentially stimulating effects of EMFs on certain marine invertebrates, highlighting the necessity for further investigation into the physiological mechanisms influenced by EMF exposure. Given the global reliance on submarine cables, understanding these interactions is crucial.
