Short summary
The oxidative potential (OP) of the PM appears to be a relevant proxy of health outcomes from PM exposure. We developed a new statistical model using a coupled approach with positive matrix factorization (PMF) and multiple linear regressions to attribute a redox activity per PM sources. Our results highlight the importance of biomass burning and vehicular sources to explain the observed OP of PM. A different contribution of the sources is observed when considering OP or the mass of the PM10.
