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.
Asthma is a complex clinical syndrome of chronic airway inflammation characterized by recurrent, reversible, airway obstruction. Airway inflammation also leads to airway hyperreactivity, which causes airways to narrow in response to various stimuli. Asthma is a common chronic condition, affecting approximately 8%-10% of Americans, or an estimated 23 million Americans as of 2008. Asthma remains a leading cause of missed work days.
