Acid deposition in various countries.

- Acid deposition is a general name for a number of phenomena, namely acid rain, acid fog.

- Acid deposition typically has a pH below 4, but this may be as low as 1.5 under seriously acidic conditions. It primarily consists of two types of compounds, namely sulphuric acid (H₂SO₄) and nitric acid (HNO₃).

- Acid deposition is a transboundary environmental problem.

- Britain: smog episodes around London, particularly in 1952.

- Germany: acid mists in central Germany and the Black Forest area, acid cold smog from Poland and former Czechoslovakia in 1985.

- Greece: intense industrialization in the Athens area causes deterioration of ancient monuments such as the Parthenon by acid deposition.

- Scotland: episodes of black acid snow in the Cairngorm moutains in 1984

- The Netherlands: corrosion of bells of the Utrecht Dom tower since 1951.

- United States: acid rains disrupts forest ecosystems and pollutes surface waters, indutrial fossil fuel combusion processes are adapted to prevent sulphur dioxide emissions.
