Spatial mapping and dimensional distribution of PM oxidative potential in Terni (Central Italy)
Over the last few decades, numerous studies have showed how the exposure to ambient particulate matter (PM) is associated to negative effects on human health (Pope et al, 2004). Moreover, the evaluation of PM exposure and toxic responses has been focused on the study of mass concentration, chemical composition and dimensional distribution of the particles (Kelly et al, 2012). However, the mechanisms behind the health effects are still not fully understood because of the complexity of PM composition.
