Acid incoming

The natural rainfall is weak carbonic acid with a pH between ....... and ........ (state two whole numbers)

Facts about acid deposition (AD) - which ones are correct

• Natural sources of sulphur dioxide: volcano emissions, hot springs and biodegradation of dead organic matter.

• Sulphur dioxide + water = sulphuric acid

• AD forms from the primary pollutants sulphur dioxide and nitrogen oxides

• Nitrogen oxides + water = nitric acid

• Natural sources of nitrogen oxides: may be cow farts and biodegradation.

Technology and clean up measures can be used to manage AD. Which of the following is not a long term solution?

• Catalytic converters

• Develop low emission vehicles.

• Use scrubbers that remove sulphur dioxide from the exhausts

• Liming lakes

• Increase energy efficiency of appliances.

Legislation means that emission standards are imposed to reduce levels of pollution being emitted that then reduces AD. The cap and trade systems is a form of legislation that controls emissions.
