Acid+Deposition

=Acid Deposition=

Mechanisms of Acid Deposition
The two primary pollutants that cause this are sulfur dioxide, and nitrogen dioxide, as shown most clearly in the below diagram.



Ammonia is also a key instrument in negating acid deposition, as they can to some extent neutralise these acids to form ammoniun sulfate and ammonium nitrate, which sink to the ground where the ammonium ion is deposited, and acidification and nitrification takes place.
