Abstract: This paper describes the evaluation of the oxidative potential of atmospheric aerosol, for the PM2.5 and PM10 size fractions, using the DTT assay. This is an indicator related with oxidative stress of particulate matter (PM) leading to potential health effects. Measured DTT activity has been correlated with aerosol concentrations and with the content of carbonaceous species on collected samples. The oxidative potential of PM associated to natural sources during Saharan Dust and sea-spray advection events is investigated and compared with non-event days.
