Scientist discovered Synthetic Biofuels in Atmosphere
5 August 2011: Scientists at the University of Miami Rosenstiel School of Marine & Atmospheric Science have discovered a technique to track urban atmospheric plumes.
The scientist discovered that half burned ethanol mixed in vehicle fuel released in the engine's exhaust has a higher 13C to 12C ratio when compared to natural emissions from most living plants. The team suggests that ethanol's unique chemical signature can be used during aircraft sampling campaigns to identify and track plumes as they drift away from urban areas. This result the New Insights to the Use of Ethanol in Automotive Fuels: A Stable Isotopic Tracer for Fossil- and Bio-Fuel Combustion Inputs to the Atmosphere" appears in the journal Environmental Science & Technology.
