    Styrene exposure in workers can cause mild sensory neuropathy, similar to chronic organic solvent exposure. Neurophysiological changes include low-amplitude sensory responses and increased fast brain activity.

    Area of Science:

    • Neuroscience
    • Occupational Health
    • Toxicology

    Background:

    • Occupational exposure to styrene is common in various industries.
    • Long-term exposure to organic solvents can lead to neurological sequelae.
    • Understanding the neurophysiological effects of styrene is crucial for worker safety.

    Purpose of the Study:

    • To investigate the neurophysiological effects of styrene exposure in industrial workers.
    • To compare styrene-exposed workers with normal controls and patients with solvent-induced neurological damage.
    • To identify specific neurophysiological changes associated with styrene exposure.

    Main Methods:

    • Electroencephalography (EEG) and neurography were performed on 33 styrene-exposed workers across three exposure levels.

  • Results were compared to a control group and a group of patients with chronic organic solvent exposure.
  • Exposure levels were categorized as above, at, or below the threshold limit value (50 ppm).

    • Main Results:

    • Ten styrene-exposed workers showed signs of mild sensory neuropathy, characterized by low-amplitude, polyphasic sensory responses.
    • These changes were similar to those observed in the mixed-solvent exposed group.
    • Increased fast activity in central and precentral brain regions was noted in styrene-exposed workers, alongside normal alpha frequency.
    • Age and styrene exposure level were significant factors in the observed neuropathy.

    Conclusions:

    • Styrene exposure is associated with mild sensory neuropathy and specific EEG changes.
    • The neurophysiological profile in styrene-exposed workers resembles that of individuals with chronic organic solvent exposure.
    • This pilot study highlights the need for considering styrene's role in occupational neurotoxicity.
