The results of the recently completed study are: Controlling emissions from mobile sources alone will not lead to achievement of the National Ambient Air Quality Standard for ozone in Basin by year 2000 or 2010, use of methanol fuels can help in reducing ozone concentrations. As a side benefit, concentrations of PAN, NO2 and PM10 are also reduced, the amount of ozone reduction is sensitive to fuel type. M100 (100% methanol) fuel is twice as effective as M85 (85% methanol, 15% gasoline) fuel when results are compared to the baseline ozone concentration formed with the use of gasoline in advanced conventional vehicles, generally, formaldehyde levels in the atmosphere will remain unchanged with the use of methanol fuel. However, formaldehyde concentrations may increase or decrease somewhat at some of the sites, depending upon specific local conditions. 收起
