Transcript of Acid Rain Project

Acid Rain Acid Rain Effect On the Forest Acid Rain Effect On River and Lakes Thank You for Watching Acid Rain Project Acid Rain Effect on Atmosphere Acid rain releases aluminum in the soil, which makes it hard for trees to take up water. Acid rain reacts with the soil and removes potassium, calcium and magnesium which are necessary for plant and tree growth. Acid rain takes away the waxy coat of the leaves that damage and prevent photosynthesis. Acid rain is deadly to our water system. PH which stands for potential of hydrogen reflects the amount of acid or alkaline in water. The pH scale ranges from 0 to 14, with 7 being the neutral point neither acid nor alkaline. Normal rainfall is 5.6 and over. Acid rainfall is anything lower than 5.6. All fishes even frogs and insects will die at a pH of 4.5. All fresh water shrimp will die at a pH of 6.0. Aquatic plants grow best at a pH of 7.0 to 9.2. The effect of acid rain upsets the ecosystem, Acid rain is any type of precipitation that has acidic chemicals. The worst, most troublesome chemicals are sulphur dioxide and nitrogen dioxide. These chemicals come from factories, power stations and vehicles burning fuels that pollute the air. When these chemicals mix with water in the air, they will form acids. Burning coal produces sulphur dioxide and cars produce nitrogen dioxide. Acid rain effect on trees. The Making of Acid Rain By: James Leaf (acid rain) Acid Rain Effect on People Acid rain effects us in many different ways. For example, in 1952, a heavy smog in London, England killed about 12,000 people. It was caused by the burning of large amounts of coal. According to Wikipedia, smog is a type of air pollution and is a portmanteau of the two words, fog and smoke. Sulphur dioxide in the air can harm people with asthma by making it even harder for them to breathe. High levels of nitrogen dioxide in the air can give people coughs and shorten their breath. Acid rain Effect on Montreal In Montreal, there is a problem with pollution. McGill university been seeing that breast cancer rates have been going up for a long time. They have been investigating various time periods, where higher rates of breast cancer was a result of more air pollution. They found a link between breast cancer and nitrogen dioxide (NO2) which brings us to automobile related pollution. How We Can Stop Air Pollution (Montreal) To reduce the amount of pollution in Montreal means reducing cars! How can you reduce the number of cars when everyone wants to drive?
Explain to people about the dangers of acid rain is the first step. People are more willing to make changes if they understand why. Reduce the number of days that people can drive. Try enforcing rules so the manufacturers will make more efficient motorcars. Try having solar panel cars and/or electric cars. Try biking and walking to work or school. At a pH of 2.5, it can melt an umbrella also melting your skin Acid Rain has effected this lake Acid rain affects the atmosphere by contaminating it. Where sulphur dioxide and nitrogen dioxide fill the atmosphere, various forms of acid rain occur. In wet conditions, there can be acid rain, acid snow and acid fog. In dry conditions there can be acid gas and acid dust. All these forms are ready to fall from the atmosphere and land on earth, in water, on buildings, on plants and people.
