But if every vehicle in the United States ran on fuel made primarily from ethanol instead of pure gasoline, the number of respiratory-related deaths and hospitalizations would likely increase, according to a new study by Stanford University atmospheric scientist Mark Z. Jacobson. His findings are published in the April 18 online edition of the journal Environmental Science & Technology.<p> "Ethanol is being promoted as a clean and renewable fuel that will reduce global warming and air pollution,'' said Jacobson, associate professor of civil and environmental engineering. ''But our results show that a high blend of ethanol poses an equal or greater risk to public health than gasoline, which already causes significant health damage."<p> "In our study, E85 increased ozone-related mortalities in the United States by about 200 deaths per year compared to gasoline, with about 120 of those deaths occurring in Los Angeles,'' Jacobson said. ''These mortality rates represent an increase of about 4 percent in the U.S. and 9 percent in Los Angeles above the projected ozone-related death rates for gasoline-fueled vehicles in 2020."<p> More here:<p> <a href="http://www.stanford.edu/group/efmh/jacobson/E85PaperEST0207.pdf">Effects of Ethanol (E85) Versus Gasoline Vehicles on Cancer<br> and Mortality in the United States (PDF)</a><br> Ethanol is widely touted as an eco-friendly, clean-burning fuel.

Thanks for bringing this to our attention. db When the “green” movement pushes for any alternative supposedly environment friendly energy, the arguments never seem to discuss the counterpoint.
