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.
The Environmental Protection Agency is investigating the role of diesel fumes and tiny soot particles in asthma and other diseases. A variety of other factors are implicated in aggravating or triggering asthma. A very common trigger is the common cold, particularly in children. Rhinitis and sinusitis are also implicated, as is gastroesophageal reflux disease (GERD).
