Yerevan - Post Report Question and Answers
Pollution index (Good, Moderate, Unhealthy, or Very Unhealthy)?
Good. About one-third of cars run on natural gas, which helps keep air pollution to manageable levels much of the time. - Oct 2009
Generally good. Armenia reminds me very much of Arizona, including the dusty haze that can settle over Yerevan in between bouts of precipitation. Fog is prevalent from mid-December through mid-February in Yerevan. - Jul 2008
Moderate. - Jan 2008
