Plain English Summary
Polish researchers exposed human immune cells called neutrophils to extremely low frequency magnetic fields at three different strengths (10, 40, and 60 microTesla) to see how it affected their production of reactive oxygen species - molecules that can damage cells. They found that only magnetic fields tuned to a specific frequency that affects calcium ions could change how these immune cells behaved, with the effect depending on the field strength.
Why This Matters
This research provides important evidence that extremely low frequency magnetic fields can alter the behavior of neutrophils, key immune system cells that serve as your body's first line of defense against infection. What makes this study particularly significant is that it demonstrates biological effects at magnetic field strengths as low as 10 microTesla - levels you might encounter from some household appliances or power lines. The finding that only fields tuned to calcium ion cyclotron resonance frequencies produced effects suggests that EMF impacts on biological systems may be highly frequency-specific, which could explain why some studies find effects while others don't. The fact that these fields altered reactive oxygen species production in immune cells raises questions about potential impacts on immune function, though more research is needed to understand what this means for human health in real-world exposure scenarios.

- 0.01,0.04, 0.06 mG
Exposure Context
This study used 0.01,0.04, 0.06 mG for magnetic fields:
- 500x above the Building Biology guideline of 0.2 mG
- 100x above the BioInitiative Report recommendation of 1 mG
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
The present study was undertaken in order to determine the effect of low frequency electromagnetic field (EMF) on reactive oxygen species (ROS) production in human neutrophils in peripheral blood in vitro.
We investigated how differently generated EMF and several levels of magnetic induction affect ROS pr...
The experiments demonstrated that only EMF tuned to the calcium ion cyclotron resonance frequency wa...
