Recent studies demonstrate that fine Particle Matter (PM) damages the human respiratory tract via intracellular redox reactivity between lung antioxidants and reactive oxidant species (ROS). Evidence continues to build that excess ROS generated by PM chemical components trigger oxidative stress biochemical mechanisms, leading to cellular/tissue injury, inflammation, and related systemic challenges, including cancer. Brown carbon (BrC) compounds are aerosol phase pollutants that are expected to oxidize PM in secondary organic aerosols (SOA). We use a DTT assay on an automated plate reader to quantify oxidant formation and characterize oxidative potentials for BrC species in local SOA systems.
