View Original AbstractStatic electric fields from power lines trigger liver stress responses in mice, forcing cells to increase protective enzyme activity.
Plain English Summary
Mice exposed to static electric fields (from power lines) for 35 days showed increased superoxide dismutase activity, an enzyme that fights cell damage. This suggests their liver cells were working harder to protect against electrical stress, indicating biological effects from field exposure.
Why This Matters
This study provides important evidence that static electric fields from high-voltage DC transmission lines can trigger biological stress responses, even when researchers downplay their own findings. The fact that superoxide dismutase activity increased significantly at both exposure levels (2.3-15.4 kV/m and 9.2-21.85 kV/m) indicates the body was mounting a defense against cellular damage. Put simply, when cells are under stress, they ramp up their antioxidant defenses. What this means for you is that living near high-voltage DC power lines may force your body to work harder to maintain cellular health. While these field strengths are higher than typical household exposures, they're representative of what people experience near major electrical infrastructure. The science demonstrates that even static electric fields can have measurable biological effects, adding to the growing body of evidence that EMF exposure isn't as benign as industry claims suggest.
