Repeated kerosene exposure caused skin and systemic toxicity in mice, which was reversible. Chronic occupational exposure in humans led to dermatitis and oil acne, highlighting the need for caution.

Area of Science:

  • Toxicology
  • Dermatology
  • Occupational Health

Background:

  • Kerosene is a common solvent and fuel, frequently encountered in occupational settings.
  • Prolonged dermal exposure to petroleum products can lead to adverse health effects.
  • Understanding the specific toxicological profile of kerosene is crucial for risk assessment.

Purpose of the Study:

  • To investigate the toxic effects of repeated dermal kerosene exposure in a murine model.
  • To assess the reversibility of kerosene-induced toxicity.
  • To correlate findings with human occupational exposure to kerosene.

Main Methods:

  • Young male albino mice were exposed dermally to kerosene on their hind feet for 7 consecutive days (15-60 min/day).
  • Histological examination of skin and lymph nodes, hematological profiling, and organ weight analysis were performed.

  • Human subjects (n=24) with chronic occupational kerosene exposure were observed for skin conditions.

    • Main Results:

    • Kerosene exposure induced histological changes in mouse footpad skin and popliteal lymph nodes.
    • Systemic toxicity included altered hematology, decreased thymus, spleen, and lymph node weights, and histological changes.
    • Observed human subjects had a high incidence of oil acne and dermatitis.

    Conclusions:

    • Repeated dermal kerosene exposure causes significant local and systemic toxicity in mice.
    • The observed toxic effects in mice were reversible after a 3-week non-exposure period.
    • Findings underscore the need for caution regarding prolonged occupational dermal exposure to kerosene.
