Short summary

We thoroughly studied the reactive oxygen species (ROS) generation potential of particulate wood combustion emissions, from different combustion technologies, fuel types, operation methods, combustion regimes and phases. ROS from automatically operated combustion devices under optimal conditions were much lower than those from manually operated appliances. We examined the impact of atmospheric aging on ROS content in SOA and determined the controlling parameters, by using an online ROS analyzer.
