1. Acid rain
- Nitrogen (II) oxide is produced in internal combustion engines on combination of nitrogen and oxygen.
- Nitrogen (II) oxide oxidized to nitrogen (IV) oxide which dissolves in water to form nitric (III) and nitric (V) acids.
- Nitric (v) acid eventually reaches ground as acid rain and causes:
? Loss of chlorophyll (chlorosis) from leaves
? Corrosion of stone buildings and metallic structures, weakening them and destroying beauty.
? Leaching of vital minerals from soils. These are converted into soluble nitrates and washed away from top soil. This leads to poor crop yields.

2. Smog formation.
- Nitrogen (IV) oxide also undergoes series of chemical reactions in air to produce one of the major components of smog.
- Smog reduces visibility for motorists, irritates eyes and causes breathing problems.

3. Eutrophication:
- Refers to enrichment of water with excess nutrients for algal growth.
- Presence of nitrate ions from nitrogen fertilizers in a water mass encourages rapid growth of algae.
- This eventually leads to reduction of dissolved oxygen in water, killing aquatic animals like fish.
- Presence of nitrate ions in drinking water may also cause ill health to humans. This is because they are converted into carcinogenic compounds.
