Abstract

Biodiesel blends are known to reduce emissions of particulate matter (PM) mass compared to diesel, but less is known regarding the impact of PM on toxicological responses, specifically PM generated in ‘real world’ operations using biodiesel. The dithiothreitol (DTT) assay is a method used to approximate oxidative potential (measure of the tendency to lose electrons) of chemical species in fuel related PM. Oxidative potential is a measure of PM ability to generate components called reactive oxygen species and is associated with adverse health effects. The DTT assay was performed on diesel and biodiesel PM collected in the summer of 2014; additionally, we measured the water soluble organic carbon (WSOC) content of the PM to investigate any relationships between DTT consumption rates and WSOC content. Our goal is to better understand the impact of ‘real world’ combustion of biodiesel in comparison to potential health effects.
