ACID RAIN Muhammad Fahad Ansari 12IEEM14Acid rain is basically rain that has a higher acid level (lowpH) than normal rain .
Causes of Acid Rain• Burning coal. Oil and natural gas in power stations makes electricity, giving off sulphur dioxide gas.• Burning petrol and oil in vehicle engines gives off nitrogen oxides as gases.• These gases mix with water vapour and rainwater in the atmosphere producing weak solutions of sulphuric and nitric acids – which fall as acid rain.
People couldnt live withoutelectricity! Therefore coal willcontinue to be burnt. Also, electricityand energy are constantly beingoverused.
How Acid Rain Affects The Environment Acid rain is an extremely destructive form of pollution, and the environment suffers from its effects. Forests, trees, lakes, animals, and plants suffer from acid rain. TREES! The needles and leaves of the trees turn brown and fall off.
HumansHumans can become seriously ill,and can even die from the effects ofacid rain. One of the majorproblems that acid rain can cause ina human being is respiratoryproblems.Many can find it difficult to breathe,especially people who haveasthma. Asthma, along with drycoughs, headaches, and throatirritations can be caused by thesulphur dioxides and nitrogenoxides from acid rain.
Research carried out in NorthAmerica in 1982, revealed thatsulphur pollution killed 51,000 peopleand about 200,000 people become illas a result of the pollution.
Solutions• 1. Sulphur dioxide can be removed from power stations chimneys but this process is expensive.• 2. Reduce the amount of electricity we use- turn TVs off at the mains, don’t leave on standby.- turn off lights when a room is not in use.• 3. Use renewable energy like wind power, solar panels, tidal power and geothermal energy.• 4. Limit the number of vehicles on the roads and increase public transport.
