Summary

Gas station attendants face mutagenicity risks from occupational exposure, as indicated by elevated micronucleus frequencies in buccal cells. This study highlights the need for regular biological monitoring and care for this high-risk group.

Area of Science:

  • Occupational Health
  • Genotoxicity Assessment
  • Biomonitoring

Background:

  • Occupational exposure to various agents can pose mutagenicity risks.
  • Gas station attendants may be exposed to genotoxic substances in their work environment.
  • Assessing cellular damage is crucial for understanding health risks in exposed populations.

Purpose of the Study:

  • To evaluate the mutagenicity risk in gas station attendants.
  • To utilize the micronucleus test in exfoliated buccal cells for risk assessment.
  • To investigate potential confounding factors such as smoking, alcohol, age, gender, and working time.

Main Methods:

  • Application of the micronucleus test on exfoliated buccal cells.
  • Analysis of micronucleus frequency in 2000 cells per individual.

  • Comparison of exposed gas station attendants with a control group.
  • Statistical analysis to determine significant differences and the influence of covariates.

    • Main Results:

    • A highly significant difference in micronucleus frequency was observed between exposed and control groups.
    • Significant differences were also found in the frequency of binucleated and broken egg cells.
    • Factors like smoking, alcohol, age, gender, and working time were analyzed for additional effects.

    Conclusions:

    • Gas station attendants represent a population at risk for mutagenicity.
    • Periodic biological monitoring is recommended for gas station attendants.
    • Appropriate health care and preventive measures should be implemented for this occupational group.
