Pollution index (Good, Moderate, Unhealthy, or Very Unhealthy)?
Unhealthy. I have had more sinus and allergy symptoms in eight months than I had in the previous eight years. Colds are frequent and tend to linger. - Jan 2008
Very unhealthy. Some days it is truly gross. The views from the altitude at Chipinque National Park show a stark difference between the pink/brown layer in the city and the blue air above. From March through November, 9 out of 10 days are smoggy and grey. - Jan 2008
