Abstract: Fine particulate matter (PM2.5) has been shown to cause oxidative stress, which has negative health consequences. The oxidative potential (OP) of PM2.5, a promising health exposure metric, was assessed in five Colombian cities using the synthetic respiratory tract lining fluid assay that tracks the depletions of glutathione and ascorbate. For this, a set of 91 integrated 2-week ambient PM2.5 samples were collected using Ultrasonic Personal Aerosol Samplers (UPAS) at background (5), traffic (37), industrial (12… Show more
