Sources of Acid Rain Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutantsknown as acid rain.
Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by the wind. As a result, the two compounds can travel long distances where they become part of the rain, sleet, snow, and fog that we experience on certain days.
Human activities are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere.
Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuelssuch as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air.
These pollutants cause acid rain. Acid Rain is Caused by Reactions in the Environment Nature depends on balance, and although some rain is naturally acidic, with a pH level of around 5.
Normal precipitation —such as rain, sleet, or snow—reacts with alkaline chemicalsor non-acidic materials, that can be found in air, soils, bedrock, lakes, and streams.
These reactions usually neutralize natural acids. However, if precipitation becomes too acidic, these materials may not be able to neutralize all of the acids.
Over time, these neutralizing materials can be washed away by acid rain. Damage to crops, trees, lakes, rivers, and animals can result.AP Environmental Science Atmosphere and Air Pollution.
STUDY. What is the pH of typical rain water in the Eastern USA? - True or False: Rain can be most acidic on Appalachian Mountains. Does this help indoor air pollution, allowing cigarettes to be smoked in the house? Another consequence of outdoor air pollution is acid rain.
When a pollutant, such as sulfuric acid combines with droplets of water in the air, the water (or snow) can become acidified. The effects of acid rain on the environment can be very serious. harmful gases or dangerous elements from such sources is causing the whole atmospheric air AIR POLLUTION ESSAY 4 ( WORDS) Air pollution is the mixing of foreign substances to the whole atmospheric air.
Increasing level of harmful gases in the environment are causing the occurrence of acid rain and depleting the ozone layer. Air pollution can also cause headaches, dizziness, and nausea.
Bad smells made by factories, garbage, or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant. Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death.
The United States Environmental Protection Agency's (EPA) website states: "Of the lakes and streams surveyed, acid rain caused acidity in 75% of the acidic lakes and about 50% of the acidic streams". Acid Rain: Acid rain is caused when pollutants present in the air mixes up with the rain and fall back on the ground.
The polluted water could dissolve away some of the important nutrients found in soil and change the structure of the soil.
