In the study, the team examined the relationships between biodiesel fuel blend, exhaust particle oxidative potential (OP), and PM composition. OP in oxidized aerosols, including engine exhaust, is commonly quantified using the DTT (dithiothreitol) assay. PM-normalized DTT Activity for biodiesel exhaust PM. to 13.6 ± 3.8
