Do you think that your country is doing enough to reduce sulphur dioxide emissions, or is it suffering from acid rain?

Sulphur dioxide

Sulphur/sulfur dioxide (SO2 or SOx) emissions cause acid rain (sulphurous/sulfurous acid (H2SO3)) when they react with water. They can irritate the lungs, giving some people asthma. Sulphur dioxide may be used as a preservative (antioxidant) in food and soft and alcoholic drinks (additives E220 and E221). It may also be used in bleaching and in purifying petroleum products.

SO2 can arise from volcanoes, from burning poor quality coal and petroleum, and from industry. SO2 is a by-product of cement making. Other sources include forest fires, volcanoes, smelting, paper manufacture and the production of sulphuric acid.

Sulphur can form another oxide, sulphur trioxide (SO3), which is a liquid. This may be formed in the atmosphere, where there is UV radiation, from SO2 and oxygen, and then go on to react with water vapour to form sulphuric acid (H2SO4). This is another component of acid rain.

Acid rain has caused extensive forests in Europe to die back, and it recognises no boundaries. It contains nitrogen oxides as well as sulphur oxides.

Recent news stories involving Sulphur Dioxide and/or acid rain include:

Hawaii's Kilauea Volcano a Big Polluter

The worst polluter in Hawaii is the Kilauea volcano, which has been belching out an average of 1,000 metric tons of sulfur dioxide daily since Jan. 3, 1983.
