N2 - Although people spend over 85% of their time indoors, the oxidative potential (OP) of particulate matter (PM) emitted from indoor sources are largely unknown. We collected PM emissions from commonly used household sources in a clean-environmental chamber and measured their OP, chemical composition, and emission rates. Finally, we performed an exploratory exposure assessment using this dataset to estimate the overall human exposure of inhaled PM mass and OP in 24-h duration. Results showed that the intrinsic OP of PM emissions from several indoor sources exceeded those of typical ambient outdoor PM2.5 levels in the US. Inhaled PM mass and subsequent OP exposure, from several indoor sources also exceeded those attributable to ambient PM, emphasizing the role that PM emissions from household sources could potentially play in PM-induced health effects.
