L. U T I O N. Identifying and Understanding Air, Water, and Soil Pollution. Air Pollution. Atmosphere need to know:. Air is more dense at sea level. 75-80% of air mass found in troposphere. Atmosphere contains 78% N, 21%O, and 1% trace gases like, methane, nitrous oxide, ozone, argon, water vapor, and carbon dioxide. Also soot, and dust..
