Acid rain creates devastating effects on the planet, as the pH of ponds, rivers, streams, and lakes is altered, and the surrounding ecosystems are impacted. This means that if you want to care for your local environment, you need to understand the basics of acid rain. Small amounts of acid rain can occur naturally due to volcanic activity.
Acid rain is a rain or any other form of precipitation that is unusually acidicmeaning that it has elevated levels of hydrogen ions low pH. It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxidewhich react with the water molecules in the atmosphere to produce acids.
We've made some changes to EPA. An ecosystem is a community of plants, animals and other organisms along with their environment including the air, water and soil. Everything in an ecosystem is connected.
Teacher professional development and classroom resources across the curriculum. Acid rain was first identified in the 19 th century, when English pharmacist Robert Angus Smith measured high acidity levels in rain falling over industrial regions of England and much lower levels in less-polluted areas near the coast. However, this pattern did not receive sustained attention until biologists began to notice sharp declines in fish populations in lakes in Norway, the northeastern United States, and Canada in the s and s.
Acid rain occurs when sulfur dioxide SO2 and nitrogen oxides NOx are emitted in the atmosphere and interact with water, oxygen and other chemicals to form sulfuric and nitric acids. Once these compounds mix with water, they fall to the ground in the form of precipitation. While normal rain has a pH around 5.
Acid Rain is any type of precipitation with acidic components that falls to the ground from the atmosphere. It can be wet or dry. These compounds can be carried away by air currents for hundreds of miles.
Development, reproduction and acaricide susceptibility of Tetranychus cinnabarinus Boisduvals Acari: Tetranychidae were investigated after long-term about 40 generations exposure to various levels of acid rain; pH 2. Deionized water pH 6. The results showed that the duration of the immature stage was significantly affected by acid rain exposure.
