This animal study examined whether 50 Hz ELF-EMF exposure at two intensities (1 mT vs 7 mT) alters hippocampal gene transcripts related to neuroplasticity and cell survival in adult rats across repeated exposure cycles. The authors report intensity- and exposure-number-dependent modulation of mRNA expression, with 1…

This study used computational dosimetry to analyze induced electric fields in a realistic human body model for a 60 Hz magnetic-field exposure system targeting the leg. Simulations indicated high EF intensities in several leg nerves and modeled conditions consistent with possible peripheral nerve stimulation. The MRG…

This animal study examined effects of a 50 Hz high-voltage electromagnetic field (5.4 kV/m) applied 2 or 4 hours per day for 25 days in albino rats. The authors report decreases in RBC, haemoglobin, and catalase activity, with increases in WBCs, liver enzymes, bilirubin, kidney-related markers, and malondialdehyde…

This ex vivo animal-tissue study tested whether ELF-EMF exposure (50 or 120 Hz for 2 or 4 hours) alters estrogenic activity in pig myometrium during the peri-implantation period. The authors report EMF-associated changes in estrogen-related gene transcripts and aromatase abundance, with progesterone diminishing some…

This animal study examined whether extremely low-frequency electromagnetic fields (ELF-EMFs) from a high-voltage source alter trace element concentrations in rat teeth and whether antioxidants (melatonin and glutathione) modify these changes. Rats were exposed 8 hours/day for 26 or 52 days, with separate sham…

This in vitro study examined whether extremely low frequency EMF exposure alters MCP-1 expression in several human cell lines. Cells were exposed to a 50 Hz sinusoidal field at 1 mT (rms), and the authors report that MCP-1 expression was modified in a cell-type-dependent manner. The findings are described as…

This in vitro study exposed SH-SY5Y human neuroblastoma cells to a 2 mT, 50 Hz magnetic field for 3 hours and assessed protein expression using proteomics. The authors report that 189 proteins changed expression in exposed cells compared with controls, with PCA/clustering separating samples by condition. They…

This in vitro study examined 50 Hz ELF-EMF effects on human T-type calcium channels expressed in HEK293 cells and on native T-type channels in primary cultured mouse cortical neurons. The authors report that ELF-EMF (0.2 mT) inhibited Cav3.1, Cav3.2, and Cav3.3 channel activity without changing Cav3.2 expression or…

This pilot study reports EMF field audits in 29 single-family residential dwellings in an urban Toronto neighborhood, measuring RF, power-frequency electric and magnetic fields, and high-frequency voltage transients. The authors frame EMF as an indoor pollutant and note a lack of international consensus on exposure…

This review describes public concerns and scientific reports of non-thermal biological effects from low-intensity ELF and RF exposures. It lists multiple health endpoints reported to be associated with ELF and/or RF and highlights the BioInitiative Report’s conclusion that a reasonable suspicion of risk exists at…
