air pollutants are a concern because they can lead to a variety of negative environmental and human health consequences. one group of such pollutants is nitrogen oxides. identify one way nitrogen oxides (nox) are commonly introduced into the atmosphere. explain how nitrogen oxides released into the atmosphere can lead to the formation of a secondary pollutant that can lead to acid deposition. describe one method for reducing nitrogen oxide emissions into the atmosphere from anthropogenic sources. nitrogen dioxide is a nitrogen oxide that can lead to the formation of ozone (o3) and photochemical smog in the troposphere. the three figures below show three scenarios involving o3 formation and destruction in the troposphere
