Sewer workers exposed to organic solvents showed increased postural sway, indicating potential central nervous system effects. Even low-level solvent exposure correlated with poorer balance, suggesting a need for further investigation into workplace health risks.

Area of Science:

  • Occupational Health
  • Neurotoxicology
  • Environmental Health

Background:

  • Occupational exposure to organic solvents can potentially affect the central nervous system.
  • Assessing neurotoxic effects in workers is crucial for maintaining workplace safety.
  • Previous studies suggest a link between solvent exposure and neurological impairment.

Purpose of the Study:

  • To investigate the relationship between organic solvent exposure and postural stability in sewer workers.
  • To assess central nervous system effects indirectly through postural sway measurements.
  • To determine if low-level solvent exposure correlates with impaired balance.

Main Methods:

  • Postural stability was measured using a microcomputer-based force platform in 28 sewer workers.

  • Four 30-second postural sway tests were conducted per worker.
  • Organic solvent exposure was quantified using a photo-ionization detector, measuring volatile organic solvents in benzene equivalence (ppm).

    • Main Results:

    • A statistically significant positive correlation (p < .05) was found between increased postural sway and organic solvent exposure.
    • Sewer workers exhibited greater postural sway compared to a nonexposed population.
    • The correlation persisted despite the measurement of very low solvent exposure levels.

    Conclusions:

    • Low-level organic solvent exposure is associated with impaired postural stability in sewer workers.
    • The findings suggest a potential neurotoxic effect of organic solvents on the central nervous system.
    • Further research is warranted to identify specific causative agents, possibly including total volatile organics, contributing to these effects.
