Investigating the Effects of Occupational Noise and Extremely Low-Frequency Electromagnetic Field Exposure on Oxidative Response in Power Plant Workers
This occupational study compared oxidative stress biomarkers across four groups: control, noise-only, ELF-EMF-only, and combined noise plus ELF-EMF exposure in power plant workers. The combined exposure group showed higher lipid peroxidation (MDA) and lower antioxidant-related measures (GSH and TAC) versus controls, while SOD activity was reduced in the noise-only and combined groups. The authors interpret these findings as evidence linking concurrent noise and ELF-EMF exposure with increased oxidative stress and call for further research and occupational safety guidance.
Key points
- Participants were assigned to control, noise-only, ELF-EMF-only, or combined noise plus ELF-EMF exposure groups.
- Noise and ELF-EMF exposures were measured using ISO 9612 and IEEE Std C95.3.1, respectively.
- The combined exposure group had the highest MDA levels compared with controls, consistent with increased lipid peroxidation.
- GSH concentrations were lower in the combined exposure group relative to controls.
- SOD activity was significantly reduced in the noise-only and combined exposure groups versus controls.
- TAC was lowest in the combined exposure group and was significantly decreased versus control and noise-only groups.
- The authors conclude concurrent noise and ELF-EMF exposure is linked to increased oxidative stress biomarkers and suggest potential health risk concerns.
- The paper calls for further research to clarify health risks and inform occupational safety measures.
