Atmospheric

Atmospheric deposition is the pollution of water caused by air pollution.

  • 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.
  • When acid rain pollutes marine habitats such as rivers and lakes, aquatic life is harmed.
