    Area of Science:

    • Toxicology
    • Analytical Chemistry
    • Biochemistry

    Background:

    • Toluene is a common volatile hydrocarbon solvent.
    • Accurate quantitation of toluene in biological samples is crucial for research and clinical diagnosis.
    • Existing methods may be time-consuming or lack sensitivity.

    Purpose of the Study:

    • To develop a rapid and accurate method for direct toluene extraction and quantitation.
    • To validate the method for use in blood and various tissue types.
    • To establish the applicability of the method in experimental and clinical settings.

    Main Methods:

    • Extraction of toluene from blood and tissues using methanol.
    • Selective adsorption of toluene onto Tenax.
    • Thermal desorption from Tenax followed by gas chromatography analysis.

    Main Results:

    • The method demonstrated linearity over a wide range of tissue concentrations (1-1,734 µg/g).
    • High accuracy and speed were achieved for toluene quantitation.
    • The procedure is effective for both blood and solid tissues.

    Conclusions:

    • A rapid, accurate, and direct method for toluene measurement in biological samples has been established.
    • This technique is suitable for basic research, including animal studies.
    • The method is applicable to clinical cases involving toluene abuse or industrial exposure.
