Answer 1

Nitrogen oxide air pollution has the following impacts:

• Nitrogen oxides are respiratory irritant.
• causes photochemical smog
• Acts as ozone precursor.

Step-by-step explanation:

• Oxides of nitrogen, when inhaled causes severe damage to the lungs and destroy the lung tissues causing severe respiratory problems.
• Presence of oxides of nitrogen in atmosphere creates a brown haze over the sky and results in photochemical smog.
• oxides of Nitrogen undergo decomposition in presence of sunlight resulting in formation of ozone. thus, it is a ozone precurzor.
• Ozone is very harmful when present at ground level.
