Article Synopsis
- A new fire investigation technique was developed using a needle extraction device that effectively gathers air samples containing volatile organic compounds (VOCs) from fire accelerants like gasoline and kerosene.
- The research involved spiking carpet and wood samples with these accelerants and monitoring the release of VOCs over a 48-hour period, confirming the collection method's effectiveness.
- Results indicated that even after 48 hours, key compounds from the fire accelerants could still be detected in the air, suggesting this method could be useful for real fire investigations.
Third-hand smoking was quantitatively evaluated with a polymer-packed sample preparation needle and subsequent gas chromatography-mass spectroscopy analysis. The extraction needle was prepared with polymeric particles as the extraction medium, and successful extraction of typical gaseous volatile organic compounds (VOCs) was accomplished with the extraction needle. For an evaluation of this new cigarette hazard, several types of clothing fabrics were exposed to sidestream smoke, and the smoking-related VOCs evaporated from the fabrics to the environmental air were preconcentrated with the extraction needle.
