Acid Rain
Acid rain contains acids that form up in the atmosphere when gas emissions such as, nitrous oxide and sulfur oxide combine with water vapour. About 70% of acid rain comes from sulfur dioxide (SO2) which dissolves into water (H2O) to form sulfuric acid. The rest of the gasses come from nitrous oxides (NOx) which are made up of various forms of nitrogen (NO2 + NO3). These gasses are caused by burning fossil fuels mainly coming from power stations and motor transport. Acid rain causes acidification of lakes and streams and contributes to damage of trees, soils and living organisms which live in the earth and lakes. Acid rain accelerates the rotting of building materials. Prior to falling to the earth, sulfur dioxide (SO2) and nitrous oxide (NOx) gases contribute to poor visibility and harm public health.
• Turn off lights, computers, and other appliances when not using them. To control the spread of transboundary pollution and acid rain, the United Nations Economic Commission for Europe (UNECE) enforced the convention on Long-Range Transboundary Pollution and acid rain in 1979. On account of that, emissions of sulfur dioxide (SO2) across Europe have dramatically declined, but increases in the volume of motor production means that emissions of Nitrous oxides (NOx) have not fallen as sharply. Therefore, transboundary and acid rain pollution still remains a problem today. • Only use electric appliances when needed.
