Activity 3.3.1 Air Pollution (Core Activity)
Air Pollution Basics Sulfur Pollutants : Sulphur Dioxide (SO2) is an incredibly important gaseous air pollutant. It is colorless but not odorless, known to have a pungent smell to it. Sulfure can combine with many other compounds to become oxidized, depending on which compound SO2 combines with the average atmospheric residence time is between 1 to 4 days. Although it may disperse long distances from its point of emission, this kind if dispersal is known as long-range transportation of air pollution. When combined with ammonium nitrate, this is what forms a fine particulate haze you see in larger cities. Nitrogen Pollutants : Nitric Oxide (NO), Nitrogen Dioxide (NO2), Nitrous Oxide (N2O), and ammonia (NH3) are the more important nitrogen-based gases. Ammonia is a colorless gas and is mostly emitted from wetlands, produced through the decomposition of dead biomass, and stays within the atmosphere for up to seven days. Nitric Oxide (NO) is colo...
