Simulation study reveals ozone-driven transfer of reactive oxygen species from indoor surfaces to particulate matter, highlighting indoor sources as key contributors to inhaled oxidative exposure.
), 44% of indoor ROS on PM is of indoor origin. An indoor source of ozone, such as an electrostatic air cleaner, also increases OPX present in indoor PM. The results of the simulations support the hypothesis that ozone-induced formation of OPX on indoor surfaces, and subsequent partitioning to aerosols, is sufficient to explain field observations. Therefore, indoor sourced ROS could contribute meaningfully to total inhaled PM-ROS.
