Some of those pollutants are gaseous like ozone and particulate like soot or dust. These pollutants can build up and can commonly be found in urban areas. Researchers from Stanford University are focusing on air stagnation to see how frequent and how long these pollutants are in the atmosphere. In addition, researchers are estimating that air air stagnation will cover 55% of the current global population. Researchers also predict that the duration of air stagnation can increase through out the years.
