Sulphur Dioxide (SO2)
Sulphur dioxide is a colourless, reactive gas that is odourless at low concentrations but has a pungent smell at very high concentrations. It is emitted primarily during the combustion of fossil fuels and the processing of sulphur-containing ores. The major sources of sulphur dioxide are fossil fuel-burning power plants, (generating electricity) and industrial boilers. Another source of sulphur dioxide is vehicular exhaust emissions.
