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.
Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. major source of indoor air pollution in developing countries is the burning of biomass (e.g. wood, charcoal, dung, or crop residue) for heating and cooking.
