Abstract

Overview

The aim of the study was to examine the impact of static magnetic field (SMF) and electromagnetic field (EMF) exposure, typical of those found near submarine cables, on key physiological parameters in the cockle Cerastoderma glaucum.

Findings

• Bivalves maintained a positive energy balance.
• Significantly lower filtration rate and energy available for individual production in SMF-exposed animals compared to controls.
• Ammonia excretion rate was significantly lower in EMF-exposed animals.
• No notable changes were observed in respiration or antioxidant enzyme activities and lipid peroxidation levels.
• Increase in protein carbonylation following exposure to both SMF and EMF.
• Significant inhibition of acetylcholinesterase activity noted following EMF exposure.

Conclusion

This study is the first to highlight the oxidative damage and neurotoxic effects in marine invertebrates due to artificial magnetic fields, underscoring the critical need for further research into their potential environmental impacts.
