Pathogenesis

Etiology

  • Fats Fat and oils are composed of triglycerides.
  • Generally, oils are liquid at room temperature, and fats are solid; palm oil is semi-solid at room temperature and often yellow in color (due to the presence of carotene).
  • Readily available as food stuffs including butter, vegetable oil (eg sunflower oil, olive oil, corn oil), suet, lard and margarine.
  • Palm oil is an edible vegetable oil used in processed foods, toiletries (soaps, shampoos), as a biofuel and for cooking (in some countries).
  • Inhalation of heated fats or oils could result in exposure to acrolein, which is formed when fats and oils are heated to high temperatures Smoke inhalation. It is a strong irritant of mucous membranes and highly reactive.

Timecourse
