Methanol economy advantages compared to a hydrogen economy: 1  Efficient energy storage by volume, as compared with compressed hydrogen. 2  A liquid hydrogen infrastructure would be prohibitively expensive. 3  Can be blended with gasoline (for example in M85, a mixture containing 85% methanol and 15% gasoline). 4  User friendly.
Two things contribute to air pollution that can cause an air quality alert: 1  Ground-Level Ozone â High-levels of ground-level ozone are frequently the cause of air quality alerts. 2  Particulate Matter â Particulate matter consists of pollutants such as dust, soot, ash and wood smoke.
This page provides forecast information on New Hampshire's air quality. The information can be used to help you plan your daily activities and protect your health. You can also learn what the current air pollution levels are in your area by clicking on the Current Air Quality link. The air quality forecast for New Hampshire is also available on the New Hampshire Department of Environmental Services' Air Quality Information Line at (800) 935-SMOG. The forecast is made for two different air pollutants: ground-level ozone and particle pollution. The pollutant whose concentration is highest relative to federal standards is shown in the table above. An Air Quality Action Day is issued when unhealthy levels are forecast for either pollutant. Ground-level ozone, more commonly called summertime smog, is formed when pollutants (nitrogen oxides and volative organic compounds) react chemically in the presence of sunlight.
