  • PAH extraction involved an ultrasonic solvent bath, with quantification by GS-MS.
  • Results indicate that a membrane filter with an Amberlite XAD-2 resin backup is necessary for complete PAH retention.

    • Impact:

    • The study recommends using a membrane filter with an Amberlite XAD-2 resin backup for comprehensive PAH air sampling.
    • This method is particularly crucial for high-temperature operations (≥150°C) such as coke ovens, charcoal, asphalt, and petroleum coking.
    • Effective monitoring strategies are vital for protecting worker health in industries with PAH exposure.
