- Abstract
Reactive oxygen species (ROS) are considered to be an indicator of particle-induced toxicity. We used a novel instrument, called Particle Into Nitroxide Quencher (PINQ), for real-time quantification of ROS for assessment of indoor particle sources. Of the sources tested, cigarette smoke was found to contain the highest ROS concentration, several times higher than incense smoke and secondary organic aerosols. The results show that PINQ could be a useful instrument in screening for particle toxicity. Since we spend the majority of our time indoors, and that much is still unknown about the toxicity of indoor particles, measurement of indoor ROS levels could be an effective way of screening for particle-induced exposure risks.
