Underwater EMF Exposure May Pose Risks to Marine Life, Review Finds

A systematic review published in Marine Environmental Research analyzed 35 years of studies on underwater electromagnetic field (EMF) exposure and found that 66% reported significant effects on aquatic organisms.

Impacts were observed across multiple species and exposure levels, including those comparable to emissions from submarine power cables. Researchers documented behavioral changes, such as altered swimming patterns and habitat use, alongside physiological effects including immune disruption, metabolic changes, and impacts on cardiovascular development.

Early life stages appeared particularly vulnerable, with effects reported in 93% of young fish and 100% of young crustaceans. Increasing EMF exposure from expanding infrastructure like offshore energy systems and communication networks raises further concern.

The study highlights a major regulatory gap, noting the absence of environmental protection standards for EMF exposure. Experts recommend integrating EMF considerations into marine planning, environmental assessments, and biodiversity policies to better safeguard ecosystems.
