Abstract

While biodiesel is considered a greener alternative to diesel fuel, there is little information on health effects from exposure to biodiesel and diesel particulate matter (PM) generated in 'real world' combustion operations. PM is comprised of chemicals which induce production of Reactive Oxygen Species (ROS), which have been linked to adverse health effects in humans. During the summer of 2014, PM samples were collected inside the cabin of a heavy duty front loader that operated on both fuel types. I exposed a human lung cell line to PM from each fuel type and measured the ROS generated. Our team also analyzed PM for water soluble organic carbon (WSOC) in order to investigate potential associations between WSOC and ROS. In this talk, I will present our experimental results examining the impact of fuel on PM composition and ROS generation. The overall goal is to better understand biodiesel’s potential health effects.
