Oxidative Potential of Particles at a Research House: Influencing Factors and Comparison with Outdoor Particles.

ABSTRACT: The oxidative potential (OP) of particles can be represented by the ability of particles to generate hydroxyl radicals in an aqueous solution which can be measured with electron paramagnetic resonance (EPR) spectrometry. The oxidative potential of particles may be a more health-relevant metric than other physicochemical properties of particles. While OP^EPR has been measured in several outdoor locations, it remains largely unstudied in indoor environments. Total suspended particle samples were collected at an unoccupied research house in eighteen four-day sampling events. The OP^EPR of indoor particles was found to be 59 % ± 30 % of the OP^EPR of outdoor particles on a sampling volume basis during normal indoor conditions in eight sampling events. However, OP<
