Answer:
the presence in or introduction into the environment of a substance which has harmful or poisonous effects.
Explanation:
In the atmosphere, water particles mix with carbon dioxide sulphur dioxide and nitrogen oxides, this forms a weak acid.
Air pollution means that water vapour absorbs more of these gases and becomes even more acidic.
When it rains the water is polluted with these gases, this is called acid rain.
