Cover Story: Oxidative potential is used as a parameter to assess inflammatory responses induced by particulate matter. The current draft of the new European Union air quality directive includes oxidative potential measurements, without specifying methods nor protocols to be used. Partnering with a regional environmental protection agency, we tested two of the most widespread oxidative potential assays (ascorbic acid and dithiothreitol) on particulate matter filters from a one-year sampling campaign conducted at an urban background measuring station. The feasibility of both methods for routine analysis was evaluated and consequent optimization of the protocols was performed. Indoor particulate matter samples were also tested to recall the importance of monitoring spaces where people spend most of their time. View this paper
