It is well established that population exposure to air pollution leads to premature mortality from respiratory, cardiovascular and other diseases. Mounting evidence suggests that main toxicological pathways follow the induction of respiratory oxidative stress upon inhalation of air pollutants by formation of reactive oxygen species (ROS) in the lung. Oxidative Potential (OP) is used as a metric for the potential of species in aerosol to deplete the lung antioxidants and form ROS. Establishing the relationships between aerosol sources and chemical composition, exposure pathways biochemical mechanisms, and health outcomes is key for risk assessment of air pollutants. This session provides a platform for international experts to share their research on the role of OP in the adverse health outcomes of air pollution exposure. Submission topic could include: OP of indoor and outdoor aerosols, application of acellular/cellular OP assays, OP and its relation to aerosol chemical and physical characteristics and emission sources.
