LePage orders study of health effects of ethanol emissions
Source: Portland Press Herald
Governor Paul R. LePage has issued an Executive Order for state agencies to study the health effects of emissions produced by the combustion of gasoline that contains ethanol, a widely used additive.
In addition, LePage directed all state agencies to implement a purchasing preference for gasoline blended with 5 percent or less of ethanol, provided the cost is comparable to gas blended with a higher concentration of ethanol.
The governor said in a statement that he issued the order because of federal mandates that have spurred increased production and use of ethanol as a fuel additive to combat air pollution.
Its important that with the increased use of ethanol mixed gasoline that we understand the environmental and health risks associated with it, LePage said. This Executive Order will help identify data so we can make better informed decisions regarding the use of ethanol.

Doing the Koch's bidding once again.
yup
when are they going to do a "study" on the efects of petrol and its products ? never .

It would be much better to study the health effects of ingesting ethanol.
Sheesh.
Fwiw, burning ethanol will produce water and co2, some co if there isn't enoygh oxygen for the combustion to completely oxidize, and in a gas mix, some aldehydes.
But it is particle free, and the by products are not considered to be harmful (well, far less than gasoline produces on its own anyway).

could also have environmental drawbacks. The team sampled Londons air during 2012 and found significantly higher levels of atmospheric ethanol, and its related oxidation product acetaldehyde, than those predicted by the NAEI, the UKs national emissions estimate. In fact, current models underestimated acetaldehyde levels by up to a factor of 40.
Despite their importance in the urban atmosphere, ethanol and acetaldehyde are seldom studied. Because theyre not part of air quality regulations, theyre not routinely measured, explains Rachel Dunmore from the University of York, who led the study. We know that they can have adverse health effects or other air quality effects such as ozone production, so the fact that we observed high levels of them piqued our interest.
Acetaldehyde is a respiratory irritant and a suspected carcinogen. Engines can generate acetaldehyde, as can ethanol being photo-oxidised in the air. In addition, both ethanol and acetaldehyde are active in other photochemical processes such as ozone production, long after they are emitted. Because ethanol is long-lived, increased emissions from somewhere like London could result in increased ozone production in downwind areas.
