Study finds PM from biodiesel blends may be 50-80% less toxic per unit PM mass than from petroleum diesel

Green Car Congress

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.
