- Acid Rain
- Rainwater always has some carbon dioxide in it, which makes it slightly acidic.
-
Other gases produced in power stations and
car engines can also dissolve in water in the
air – these gases include sulphur dioxide.
- They make the rain more acidic – rain that is more acidic than normal (less than about pH 5.2) is called acid rain.
- Acid rain makes lakes and rivers acidic, which harms fish and other life. It also damages trees, buildings made of limestone or marble, and makes metal corrode.
- The amount of acid rain falling in Europe and North America has been reduced by removing sulphur from car fuels and by removing sulphur dioxide from power station waste gases.
