Ocheni and colleagues at the University of Maiduguri review research from 2015 to 2025 on occupational exposure to 50 Hz magnetic fields around high-voltage transmission switchyards, in the Nigerian open-access African Journal of Health, Safety and Environment. They report that ELF magnetic fields induce electric currents in tissue that can affect cell membranes, disrupt neuroendocrine function and generate oxidative stress, with occupational studies describing neurological, cardiovascular, reproductive and sleep effects. The authors conclude that ICNIRP and IEEE guidelines leave significant gaps on dose-response and long-term cumulative effects, and recommend health surveillance and strict exposure-limit adherence.

"Findings indicate that ELF magnetic fields penetrate biological tissues inducing electric currents that potentially affect cellular membranes, disrupt neuroendocrine function and generate oxidative stress."

— Ocheni et al., African Journal of Health, Safety and Environment

"Occupational studies reported associated health effects such as neurological disturbances, cardiovascular changes, reproductive dysfunction, sleep disorders and altered melatonin secretion."

— Ocheni et al., African Journal of Health, Safety and Environment

"The present exposure guidelines from the International Commission on Non-Ionising Radiation (ICNIRP) and the Institute of Electrical and Electronics Engineers (IEEE) provide protective frameworks, yet there exist significant knowledge gaps regarding dose-response relationships and long-term cumulative effects."
