  1. Study of human neurovegetative and hematologic effects of environmental low-frequency (50-Hz) electromagnetic fields produced by transformers.

    Article - En anglais

    A survey of neurovegetative and hematologic disorders was conducted in a population (n=13) exposed occupationally to environmental electromagnetic fields ; the population was matched with 13 control subjects.

    The exposed subjects worked at least 8 h/d for 1-5 y in premises located above transformers and high-tension cables, and the subjects were submitted to low-frequency electromagnetic fields (i.e., 50 Hz) of 0.2 muT-6.6 muT.

    The subjects were matched with respect to socioeconomic category, sex, and age with a control population of subjects that worked in premises outside of the immediate vicinity of transformers or high-tension cables.

    The exposed population had a significant increase in degree of certain neurovegetative disorders (i.e., physical fatigue, psychical asthenia, lipothymia, decreased libido, melancholy, depressive tendency, and irritability).

    In addition, the population experienced a significant fall in total lymphocytes and CD4, CD3, and CD2 lymphocytes, as well as a rise in NK cells.

    Leukopenia and neutropenia were also observed in two persons permanently exposed to doses of 1.2-6.6 muT.

    The disorders disappeared when exposure stopped, and they reappeared on reexposure.
