Acid Rain in Europe :: Papers

Acid Rain in Europe Introduction ============ The atmosphere is like a film of gases, which makes the planet habitable. If this layer was not present there would be no life on earth. It is a fact that the health of plants, animals and humans depends upon a very important factor 'pollution'. Although, all kinds of poisonous waste is continuing to be put into the atmosphere. These poisonous gases are being produced when fossil fuels are burnt, as a result of this acid rain forms which further more results in numerous problems damaging forests, lakes, rivers, land, plants and animals. The main culprits of burning fossil fuels are MEDC's, which insist on maintaining their high standards of living. What is acid rain? Rain is naturally acidic but the term 'acid rain' is usually referred to as rain, which has been made more acidic than it should be due to the atmosphere absorbing the gasses emitted from the burning of fossil fuels. The gases are oxides of nitrogen and sulphur. Nitrogen oxide is usually given Nox as there are many of them, sulphur oxide SO2 and water H2O When these mix together they form acids such as sulphurous acid (H2SO3). Acid rain can be deposited in three ways: * Wet deposition - The deposition of pollutants in rain and snow mainly affects upland areas. * Dry deposition - The deposition of gases and particles directly onto terrestrial surfaces. * Cloud deposition - The capture of cloud droplets that contain concentrated pollutants. We can measure how acidic the rain actually is by the pH scale, 7 is neutral, below that is acidic above that is alkaline. A 'log scale' can be used for example pH 6 is ten times more acidic than pH 7, so pH 5 is one hundred times more acidic than pH7. Case study: An investigation to show how acid rain is affecting Europe. What are the causes of acid rain? Acid rain was first found in Scandinavia in the late 1950's and at
