Pollution index (Good, Moderate, Unhealthy, or Very Unhealthy)?
Moderate to unhealthy. Very limited, if any, industrial pollution. The sand dust often makes it difficult to breathe. - Dec 2009
This is a very dusty place. The sand storms, as they call them, are really nothing more than a layer of dirt settling down over the sky, obscuring the sun and coating everything. There is very little in the way of industrial pollution, though. - Sep 2008
