Bluetooth earbud magnetic fields increased air pollution in mouse brains, inducing neurotoxicity

A new study published by Zhang et al. in ACS Nano found that magnetic fields emitted by Bluetooth earbuds and cell phones increased the accumulation of air pollution–derived magnetite nanoparticles in the brain and triggered neurotoxic effects in mice. To model real-world exposure, the researchers first disassembled earbuds and cell phone components to measure their magnetic fields, a type of non-ionizing electromagnetic field (EMF). They then r…
