  • Abstract:
    Sustainability of our transportation system depends on making well-informed choices on

    vehicle energy sources for human and goods mobility. Motor vehicles operating on fossil

    fuels are a significant source of air pollution risk and challenge the ability of humans to

    mitigate climate change. Biodiesel is a low carbon fuel substitute for petroleum diesel,

    but relatively little is known about how exposure to biodiesel combustion particles affects

    chronic diseases such as asthma and type II diabetes mellitus (T2DM). This study

    examined the effect of particulate matter (PM) generated by the combustion of

    commercially available petrodiesel and soybean biodiesel fuels on inflammation and

    metabolic dysfunction using two types of in vivo experiments. To evaluate inflammation

    response, oropharyngeal 3-day exposures of females to B20 (20% biodiesel/80%

    petrodiesel by volume) and B0 (100% petrodiesel) particles from a light-duty diesel

    engine operating on a semi-transient cycle were followed by lung fluid and tissue

    biochemical analysis. Prenatal exposure effects on offspring growth and metabolism were

    evaluated by maternal exposure during gestational days 9-17 (delivery 18-20 days) and

    monitoring offspring for 12 months. Prenatal exposure to exhaust PM from petrodiesel

    fuel combustion had different metabolic effects in male vs. female offspring. For B20

    exhaust PM, the number of offspring was too low to detect differences. The results of this

    study suggest that males and females may have differential risk for metabolic dysfunction

    after prenatal exposure during gestation. Future studies should be conducted to quantify

    sex-specific effects on exposure to vehicle exhaust PM from biodiesel fuel blends.
