Chinese electrical workers exposed to power line electromagnetic fields showed no cognitive impairment compared to unexposed workers in standardized brain function tests.

Plain English Summary

Summary written for general audiences

Researchers tested cognitive and brain function in 310 Chinese electrical workers regularly exposed to power line electromagnetic fields during equipment inspections, comparing them to 300 unexposed office workers. The study found no differences in memory, reaction time, or other brain performance measures between the two groups. This suggests that occupational exposure to power frequency electromagnetic fields may not impair basic cognitive abilities.

Study Details

We aimed to evaluate the interference of 50 Hz extremely low frequency electromagnetic field (ELF-EMF) occupational exposure on the neurobehavior tests of workers performing tour-inspection close to transformers and distribution power lines.

Occupational short-term “spot” measurements were carried out. 310 inspection workers and 300 logisti...

In 500 kV areas electric field intensity at 71.98 % of total measured 590 spots were above 5 kV/m (n...

Results of neurobehavior tests among different age, seniority groups showed no significant changes. Neurobehavior changes caused by daily repeated ELF-EMF exposure were not observed in the current study.
