Biodiesel Emissions Shown to Contain Respiratory Disease-Linked Compounds
(Medical Xpress) Compounds that affect respiratory health have been found in biodiesel exhausts. This might lead to restrictions on the use of this form of biofuel as an alternative to fossil fuel, according to researchers from the Queensland University of Technology (QUT).
“With fossil fuel reserves dwindling, developing renewable alternative fuels is important,” postdoctoral fellow Dr Nicholas Surawski says, “but we should be particularly careful to protect against unwanted respiratory illness when we adopt new transport fuels.” The team is now looking at ways of cleaning up biofuel exhausts.
…Using specialised analytical monitoring equipment developed at the University, they discovered that burning diesel fuels with a high percentage of biodiesel (up to 80%) produced higher emissions of compounds linked to respiratory disease. These biologically active compounds are called reactive oxygen species and form on surface of small soot particles in the exhaust emissions. READ MORE Abstract
