Relative Toxicity of Exhaust Particulate After Accelerated Thermal Oxidation of Recycled Vegetable Oil Biodiesel Fuel

Research Product Type
Research Report
Given that today’s real-world diesel fuel supply is comprised of biodiesel as a blendstock with petrodiesel, understanding how addition of biodiesel affects exhaust particle properties and their subsequent effect on human health is critically important. Here, samples of a commercial waste vegetable oil biodiesel B100 fuel were subject to thermal oxidation at 110°C for 5, 10 or 20 hr before diesel engine dynamometer emissions testing as the neat fuel (B100) and as a 20% v/v biodiesel blend (B20) with petrodiesel.

The Safe Systems Pyramid

Research Product Type
Policy Brief
The Safe Systems Pyramid presented in this policy brief is a tool that incorporates public health principles to evaluate transportation safety policies and interventions. The Safe Systems Pyramid can help transportation practitioners and decision-makers prioritize projects for safety and communicate priorities to the public.

Understanding of Tire-Wear Gaseous Emissions and their Impact on Secondary Aerosol Formation from On-Road Vehicles

  • Principal Investigator Georgios Karavalakis, Ph.D.
  • University of California, Riverside
In this study, the researchers will measure the gaseous emissions from the off-gassing of tires during laboratory and real-world testing conditions. The researchers will also evaluate the secondary organic aerosol forming potential from the off-gassing of tires during only laboratory conditions using state-of-the-art instrumentation.
