The various forms of pollution caused by acid rain

Acid rain formed with dust or gasses is called dry deposition. Governments are now beginning to admit that acid rain is a serious environmental problem and many countries are now taking steps to reduce the amount of sulphur and nitrogen emissions.

However, if precipitation becomes too acidic, these materials may not be able to neutralize all of the acids.

The various forms of pollution caused by acid rain

This leads to fish-eating birds and animals being affected also. Although acid-rain gases may originate in urban areas, they are often carried for hundreds of miles in the atmosphere by winds into rural areas. Lakes, like those in the Adirondack Mountains in New York, have had nearly the entire population of fish die off due to acidification. Something with a pH value of 7, we call neutral, this means that it is neither acidic nor alkaline. 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. The people of Norway and Sweden have successfully used liming to help restore lakes and streams in their countries. The volunteers collected samples, checked for acidity, and reported back to the organization. It is not just trees that are affected by acid rain, other plants may also suffer. This pattern of high acidity is caused by the large number of cities, the dense population, and the concentration of power and industrial plants in the Northeast. This can include rain, snow, fog, hail or even dust that is acidic. Acid Rain What is Acid Rain?

Planet Earth Shares Dead trees line a riverbank near Norilsk, Russia, formerly a major industrial center in Siberia, and one of the most polluted cities in the world, according to National Geographic.

Until relatively recently air pollution has been seen as a local issue.

Prevention of acid rain

That is a condition that will dissolve rocks," said study team member John Valley. In , a group of scientists modified the acidity of Norris Brook, New Hampshire, and observed the change in species' behaviors. As acid rain raises the level of acidity, fish tend to die off. Unfortunately all this does is push the polluting gases up into the clouds allowing emissions to float away on the wind. The acidic particles and gases may deposit to surfaces water bodies, vegetation, buildings quickly or may react during atmospheric transport to form larger particles that can be harmful to human health. Many plants, such as evergreen trees, are damaged by acid rain and acid fog. In addition, the prevailing wind direction brings storms and pollution to the Northeast from the Midwest, and dust from the soil and rocks in the Northeastern United States is less likely to neutralize acidity in the rain. Because bases counteract acids, these soils tend to balance out some of the acid rain's acidity. When any type of fuel is burnt, lots of different chemicals are produced. Acid rain makes such waters more acidic, which results in more aluminum absorption from soil, which is carried into lakes and streams. The biggest contributors to acid rain are sulfur dioxide and nitric oxides. From these gases, airborne sulfuric acid H2SO4 and nitric acid HNO3 can be formed and be dissolved in the water vapor in the air. Even the strongest recorded acid rain is only about as acidic as lemon juice or vinegar and we know that these don't harm us - so why do we worry about acid rain? Environmental Protection Agency Geographic distribution of acid rain Acidity in rain is measured by collecting samples of rain and measuring its pH. Acid rain and fog also damage forests, especially those at higher elevations.

This weathering process, over hundreds of millions of years, turned the Appalachian Mountains from towering peaks as high as the Rockies to the rounded knobs we see today. When acid deposition is washed into lakes and streams, it can cause some to turn acidic.

what are the effects of acid rain

Human activities are the main cause of acid rain. When it hit the air, it turned into sulfuric acid, generating a downpour of acid rainaccording to a paper published in in the journal Nature Geoscience.

The same amount of acid rain seems to have more effect in some areas than it does in others. Some soils are better able to neutralize acids than others.
