Outline
More than 100 volatile organic compounds (including 36 carcinogens) were identified in the clothing-mediated thirdhand smoke (THS) by using a proton transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS). Significant differences were found in the component and amount for the THS released from different clothing material. Specifically, the amount of THS released from polyester was significantly lower than that released from cotton. Furthermore, the amount of THS released from clothing exponentially decreased as increasing time, and the decrease ratio was more than 80% after 30 minutes, suggesting that the clothing-mediated THS pollution could be reduced if the smokers stay outdoors for more than 30 minutes after smoking cigarettes. This study provided a useful method for the investigations of clothing-mediated THS pollution, deepening the understanding on the release characteristics of THS pollution from clothing, which should have great significance in reducing the THS exposure for non-smokers.
