Occupational exposure to organic solvents (OS) negatively impacts neuropsychological performance in petrochemical workers. Even within regulatory limits, OS exposure is linked to poorer cognitive function and increased neurotoxicity symptoms.

Area of Science:

  • Neuroscience
  • Occupational Health
  • Toxicology

Background:

  • Petrochemical workers face potential exposure to organic solvents (OS).
  • Neuropsychological deficits can arise from occupational chemical exposures.
  • Understanding the impact of OS on cognitive function is crucial for worker safety.

Purpose of the Study:

  • To estimate neuropsychological performance in Mexican petrochemical workers.
  • To determine the association between organic solvent exposure and neurobehavioral outcomes.
  • To assess the impact of OS exposure on cognitive function in a Mexican petrochemical workforce.

Main Methods:

  • A cross-sectional study involving 203 petrochemical workers (102 exposed to OS, 101 unexposed).
  • Neuropsychological assessment using the Neurobehavioral Core Test Battery.

  • Quantification of OS exposure through urinary metabolite analysis for toluene, xylenes, and benzene.

    • Main Results:

    • Exposed workers demonstrated significantly poorer performance across most neuropsychological tests (p<0.05), excluding the Santa Ana test.
    • Regression models confirmed that OS-exposed workers made more errors and took longer to complete tests (p<0.05).
    • A higher probability of neurotoxicity symptoms was observed in the exposed group (OR: 2.93; 95% CI: 0.96, 8.96).

    Conclusions:

    • Occupational exposure to organic solvents is associated with diminished neuropsychological performance.
    • Even exposure levels compliant with current Mexican regulations correlate with reduced cognitive function.
    • Findings highlight the need for stricter controls and monitoring of OS exposure in the petrochemical industry.
