    Area of Science:

    • Forensic Science
    • Toxicology
    • Cell Biology

    Background:

    • Alveolar macrophages in smokers' lungs contain pigment granules.
    • These granules exhibit inherent fluorescence under UV light.

    Purpose of the Study:

    • To identify a method for detecting smoking habits in deceased individuals.
    • To characterize the fluorescent properties of smoker's lung cells.

    Main Methods:

    • Extraction of substances from smoker lung cells using various solvents.
    • Testing the eluting effect of polar solvents like tetrahydrofuran and Folch's solution.
    • Centrifugation of specimens and analysis of the fluorescent chloroform phase.

    Main Results:

    • Tetrahydrofuran and Folch's solution reduced the fluorescence of pigment granules.

    Related Experiment Videos

  • Fluorescent substances transferred to the chloroform phase when using Folch's solution.
  • The fluorescence test is effective regardless of corpse freshness.

    • Conclusions:

    • A fluorescence-based method can determine smoking habits from lung tissue.
    • This technique aids in the identification of deceased individuals.
