Acid Rain Facts: You Need To Read & Be Safe For Life

Creating an acidic environment with incessant pollution is responsible for growing instances of acid rain.

Acid rain, often known as acid deposition, corresponds to any sort of precipitation that includes acid content, such as sulfuric or nitric acid, that falls to the ground wet or dry from the atmosphere. This could include acidic rain, snow, fog, hail, or even dust.

Nitrogen oxides (NOX) and Sulfur dioxide (SO2) are gases that are emitted into the atmosphere and carried by wind and air currents, resulting in acid rain.  SO2 and NOX react with water, oxygen, and other molecules, sulfuric and nitric acids are generated. This acid rain falls on the soil after interacting with water and other substances. When gases like nitrogen oxides and sulfur dioxide.

John Evelyn, reflecting on the bad condition of the Arundel marbles in the 17th century, noticed the corrosive effect of dirty, acidic city air on limestone and marble.  Sulfur dioxide and nitrogen oxide emissions into the environment have grown since the Industrial Revolution. In Manchester, England, in 1852, Robert Angus Smith was the first to demonstrate the link between acid rain and pollution.

Scientists began watching and analyzing the phenomenon in detail in the late '60s. Robert Angus Smith originated the term 'acid rain' in 1872. The first person to investigate a dead lake from Canada was named Harold Harvey. The primary focus of this study was initially on the local impacts of acid rain. Waldemar Christofer Brøgger was the first to recognize long-distance pollution trafficking between the United Kingdom and Norway. The New York Times ran reports from the Hubbard Brook Experimental Forest in New Hampshire about the detrimental environmental effects of acid rain in the '70s, which raised public awareness of the problem in the United States.

Comprehensive investigations of precipitation chemistry over the last 20 years have convincingly demonstrated that severely polluted precipitation falls across significant parts of Scandinavia and that the severity and spatial extent of this pollution are growing. Large amounts of Hydrogen, SO= 4, and NO 3 ions, as well as heavy metals like Cu, Zn, Cd, and Pb, are found in precipitation in southern Norway, Sweden, and Finland. These toxins originate as air pollutants in heavily industrialized areas of the United Kingdom and Central Europe and are transported over long distances to Scandinavia, in which they are accumulated in precipitation and dry-fallout.

Acidification of freshwater and the resulting reduction and loss of fish and other aquatic animals population were first observed in Norway in the '20s, and since then, salmon have been eradicated from many rivers and several lakes in Sørlandet  (southernmost Norway).

Acid precipitation has rightly risen to the top of Norway's environmental worries, causing the government to launch a major research project in 1972 called 'Acid precipitation — Effects on Forest and Fish.'

The international acid rain information center has been set up in Oslo, Norway.

Manchester is Europe's acid rain capital. In an Irish study, it was found that the rain dissolves construction materials faster in downtown Manchester than at any other test site from Donegal to Athens. A further British testing site, Liphook in Hampshire, had similarly poor results.

During the 20-month course of the study, an average of 101.4 lb (46 kg) of stone was washed from every square meter of limestone, sandstone, and marble in Manchester, according to Paul O'Brien and colleagues from Trinity College, Dublin. The city was hit the hardest because its rain was the most acidic, despite the fact that its rainfall was among the lowest throughout the study period.

Air Pollution And Acid Rain

What is acid rain?

Any type of precipitation containing significant levels of nitric and sulfuric acid is referred to as acid rain. It can also take the form of snow, fog, or little fragments of dry debris that fall to the ground. Normal rain has a pH of 5.6. Normal rain is mildly acidic, whereas acid rain has a pH of 4.2 to 4.4.

What are the effects of acid rain?

Some chemicals are released by rotting flora and erupting volcanoes, but the majority of acid rain is caused by human activities. Coal-fired power generation, manufacturing, and autos are the primary contributors.

Sulfur dioxide (SO2) and nitrogen oxides (NOx) are emitted into the atmosphere by humans while burning fossil fuels. When these pollutants combine with water, oxygen, and other chemicals in the air, sulfuric acid, and nitric acid are generated. Winds have the potential to transport acidic substances hundreds of kilometers through the sky. When acid rain hits the ground, it forms rainwater runoff, enters waterways, and seeps into the soil. When nitric acid and sulfuric acid are

Sulfur dioxide and nitrogen oxides are not principal greenhouse gases that cause global warming. Nitrogen oxides, on the other hand, contribute to the development of ground-level ozone, a major pollutant that is potentially dangerous to humans and other adverse effects. Both of these gases are dangerous to the environment and can deteriorate human health as they can rapidly spread through air pollution and acid rain.

A mixture of dangerous gaseous substances is discharged into the environment when the air is contaminated. Sulfur dioxide and other nitrogen oxides are among these gases. Once released into the atmosphere, these gases mix with other gases and combine with water (from bodies of water such as lakes, rivers, and other bodies of water that are initially evaporated) to form clouds. As a consequence, whenever it rains, the rainwater that falls is acidic, causing pollution-related acid rain.

As the toxic gases in the form of SO2 and NOX enter the atmosphere along with wings, it leads to the normal rainwater becoming acidic, resulting in acid rain. These two gases are created by natural sources such as volcanic eruptions as well as from the burning of fossil fuels. As these two gases interact with the gases and water vapors present in the environment, they mix quite easily with all other pollutants present in the atmosphere. Then the rain water falling on the Earth turns into acid rain.

Acid rain can cause harm to everyone ad not only those are affected that reside near these areas, but air carries both these gases across great distances into different countries.

Acid snow is the frozen version of acid rain. Acid snow is a type of precipitation contaminated by huge levels of sulfur and nitrogen oxides. Acid snow is formed when these are released by factories, power plants, automobiles, and other sources.

Acid Rain pH

The pH scale can be used to assess the acidity of a substance. Basic objects are those that aren't particularly acidic. The range of the scale is from 0 pH (the most acidic) to 14 pH (the most alkaline) (the most basic) on a pH scale. Pure water is known to have a 7 pH, which is neutral pH according to the pH scale. This number is neutral pH, meaning pure water is not basic or acidic.

The pH of normal, clean rain is between 5.0 pH and 5.5 pH, which is somewhat acidic. Rain becomes significantly more acidic when sulfur dioxide or nitrogen oxides mix, which generates electricity by power generation and vehicles.

Acid rain is known to have a pH of 4.0. When the pH drops from 5.0 ph to 4.0 pH, the acidity increases by a factor of ten pH.

The pH of acid rain is usually between 4.2 pH and 4.4 pH on a ph scale. For observations of wet deposition, researchers, ecologists, and policymakers rely on the National Atmospheric Deposition Program's  National Trends Network. The NADP/NTN monitors acid rain data at over 250 monitoring stations in the United States, Canada, Alaska, Hawaii, and the US Virgin Islands. Dry deposition, unlike wet deposition, is difficult and costly to measure. The Clean Air Status and Trends Network provides dry deposition estimates for nitrogen and sulfur contaminants (CASTNET). CASTNET measures air concentrations at more than 90 places.

Now that you know what acid rain is and the government policies, you can, too, help to reduce acid rain.

Recognize the Issue.

Understanding the problem and potential remedies is the first step toward reducing acid rain. You can now inform people about this environmental issue. You can educate others on how to reduce acid rain too. Small actions turn into bigger rewards in the future.

When not in use, turn off lights, laptops, televisions, video games, and other electrical devices.

Encourage your parents to get energy-efficient appliances such as refrigerators, lights and washing machines. Energy Star certification may be available for such equipment.

Try to keep your air conditioning usage to a minimum.

When you depart on vacation, ask your parents to adjust the thermostat (the device that controls the temperature in your home).
