View Original AbstractResearchers concluded that electromagnetic field emitted from a cellular phone might produce oxidative stress in brain tissue of guinea pigs.
Plain English Summary
In brain tissue, the MDA level increased and GSH level and CAT enzyme activity decreased in EMF-exposed guinea pigs, while vitamins A, E, and D3 levels did not change. In blood, MDA, vitamins A, D3, and E levels, and CAT enzyme activity increased, while GSH level decreased in the EMF-exposed guinea pigs.
Why This Matters
Fourteen male guinea pigs were randomly divided into two groups of seven: a control group and a treatment group exposed to the electromagnetic field. Control guinea pigs were housed in a separate room without exposure to the electromagnetic field. Blood and brain samples were collected after the 30-day experimental period for biochemical analysis. The researchers noted that more studies are needed to demonstrate whether these effects are harmful or affect neural functions.
Exposure Details
- SAR
- 0.95 W/kg
- Source/Device
- 890- to 915-MHz EMF
- Exposure Duration
- 12 h/day (11-h 45-min stand-by and 15-min spiking mode) for 30 days
Exposure Context
This study used 0.95 W/kg for SAR (device absorption):
- 2.4x above the Building Biology guideline of 0.4 W/kg
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
This study was designed to demonstrate the effects of 900-MHz electromagnetic field (EMF) emitted from cellular phone on brain tissue and also blood malondialdehyde (MDA), glutathione (GSH), retinol (vitamin A), vitamin D3 and tocopherol (vitamin E) levels, and catalase (CAT) enzyme activity of guinea pigs.
Fourteen male guinea pigs, weighing 500–800 g were randomly divided into one of two experimental gro...
It was found that the MDA level increased (P < 0.05), GSH level and CAT enzyme activity decreased (P...
It was concluded that electromagnetic field emitted from cellular phone might produce oxidative stress in brain tissue of guinea pigs. However, more studies are needed to demonstrate whether these effects are harmful or/and affect the neural functions.
