Petrol exposure significantly impacts cognitive functions in workers, affecting memory and psychomotor abilities. These findings highlight the neurotoxic risks associated with occupational petrol exposure.

Area of Science:

  • Neuroscience
  • Occupational Health
  • Environmental Toxicology

Background:

  • Petrol contains volatile organic compounds known to affect the nervous system.
  • Petrol pump workers face chronic exposure to these neurotoxic substances.
  • Understanding the specific behavioral and cognitive impacts is crucial for worker safety.

Purpose of the Study:

  • To investigate the effects of petrol exposure on the central and peripheral nervous systems of petrol pump workers.
  • To assess cognitive functions, including memory, intellectual capacity, and psychomotor abilities.
  • To compare behavioral outcomes between exposed workers and a control group.

Main Methods:

  • Behavioral studies conducted on 90 petrol pump workers and 64 controls.
  • Utilized a battery of neuropsychological tests: Maudsley Personality Inventory (MPI), Benton Visual Retention Test, Digit Span Test, Progressive Matrices, Digit Symbol Test, and Mirror Drawing Test.

  • Statistical analysis to compare performance between exposed and control groups.

    • Main Results:

    • Significant adverse effects on immediate and delayed memory in exposed workers.
    • Intellectual capacity and psychomotor ability were significantly impaired (P < 0.01).
    • Visuomotor learning ability showed greater impairment (P < 0.05) in exposed subjects compared to controls; personality traits like stability and extroversion-introversion remained unaffected.

    Conclusions:

    • Occupational petrol exposure detrimentally affects cognitive functions, particularly memory and psychomotor skills.
    • Neurobehavioral assessments are vital for monitoring the health of workers in high-exposure environments.
    • Findings underscore the need for enhanced safety measures and health surveillance programs for petrol pump workers.
