Abstract

Study Overview

The aim of the study was to determine the effect of static magnetic field (SMF) and electromagnetic field (EMF), of values usually recorded near submarine cables, on the bioenergetics, oxidative stress, and neurotoxicity in the cockle Cerastoderma glaucum.

Key Findings

• Bivalves maintained a positive energy balance, but the filtration rate and energy available for individual production were significantly lower in SMF-exposed animals compared to the control treatment.
• No changes in respiration were observed; however, ammonia excretion rates were significantly lower after exposure to EMF.
• While no changes were noted in antioxidant enzyme activities or lipid peroxidation, exposure to both fields resulted in increased protein carbonylation.
• Significant inhibition of acetylcholinesterase activity was observed after exposure to EMF, indicating potential neurotoxic effects.

Conclusion

This study reveals for the first time the oxidative damage and neurotoxicity in marine invertebrate after exposure to artificial magnetic fields, highlighting the urgent need for further research into these effects.
