  Sulphur Dioxide and Nitrogen dioxide if I remember correctly and it mainly comes from burning things like coal in power stations.
  
  People reduce it by running the exhaust gases of a powerstation through a special device called a scrubber that helps remove the sulphur and nitrogen compounds.
  
  I help reduce it by not owning a car and using as little power as I can

  Acid rain is caused mostly by the compounds nitrogen dioxide and sulphur dioxide. These are produced through the burning of fossil fuels. So power plants emit them as do vehicles running on petrol. When the gases are in the atmosphere, reactions high up in the sky occur and acidic pollutants are produced which rain down. Now emissions of these compounds are being reduced through the use of regulations which stop industries emitting too much and through the development of cleaner technologies. I work for the Environment Agency who is responsible for much of this work.

  I think acid rain is caused by the pollution from power plants (coal and oil but not nuclear)
