Acid rain may deteriorate buildings and sculptures by eroding the materials and corroding the metal that make them up. Architects used limestone, marble, steel, and brass as weather-resistant materials. But all can be damaged by acid rain.
Limestone, marble, and granite are all made of calcium carbonate. When exposed to acid rain, this material can become weathered and eroded. The particles from the stone can be blown by wind into building structures where they can cause damage or collect in large quantities on roof tops or inside windows. Over time, the stones may need to be replaced or treated to prevent this erosion.
Steel and brass are both metals that can be damaged by acid rain. When exposed to acid conditions, steel will oxidize and develop a rusty color while brass remains yellow. Both metals can become tarnished over time if they are not cleaned regularly.
If you are a painter or carpenter who works onsite, you should take precautions to protect against exposure to acid rain. Wear protective clothing (including gloves) that protects you from contact with chemicals found in acid rain. Use water to rinse your skin and clothes after working on sites affected by acid rain. This rinsing action helps remove any chemicals on your body that might be absorbed through your skin.
Acid rain harms buildings and structures by dissolving stone or corroding metal exposed to the elements. Acid rain can dissolve calcium carbonate or calcium-based chemicals in some of these materials. This can lead to problems such as crumbling statues, broken windows, or eroded roadways.
The walls and roofs of homes are made of plaster or cement that contain lots of water inside them. When acid rain falls on this material, it reacts with the moisture within the walls to create a saltwater solution harmful to wood framing and other organic materials. This would include most of the wood used in houses, which is typically lumber that has been cut from trees grown in acidic soil.
Corrosion is another problem that results from exposure to acid rain. Metal surfaces are especially vulnerable to corrosion when they are wet, which happens whenever it rains. Corrosive substances in acid rain can eat away at metal over time, leading to structural failure if not repaired quickly. Corrosion also causes color change in metals like bronze, silver, or gold. As these metals lose weight due to oxidation, they can look like they're deteriorating even though they remain structurally sound.
Finally, acid rain can harm the paint job on your home. The particles in acid rain can travel through thin layers of paint and damage the underlying material underneath.
Acid rain wreaks havoc on stone buildings and other structures, even culturally valuable ones. Acid rain destroys structures and statues built of these materials in the same way as limestone and marble buffer acidic water. The reduced pH of rain and fog is doing havoc on cultural items, a long-known phenomena. In fact, it has been known since 1772 when George Washington ordered that all public monuments in his state be coated with bitumen or stucco to prevent erosion due to acid rain.
The problem has become more severe as the amount of acid in precipitation has increased due to man-made sources. Modern industrial processes produce large amounts of sulfur dioxide and nitrogen oxides that react with moisture to form sulfate and nitrate acids. These substances are highly soluble and can travel great distances before forming droplets that fall as rain or snow. Once in water, the acids eat away at rocks and minerals, including calcium carbonate which makes up much of the shell of marine organisms. This process is called acidification.
Cultural resources are important to the economy and quality of life for individuals and communities. They include sites such as museums, archeological sites, and private homes. Protecting these resources is essential for future generations who will want to see them preserved for their own use and enjoyment.
In conclusion, acid rain affects cultural objects by destroying them through dissolution and corrosion.
Acid rain kills fish and forests, but it also accelerates chemical weathering. As a result, stone structures and statues are also harmed. This is exacerbated when the rock is limestone as opposed to granite. Limestone is more soluble than granite; therefore, it will wash away faster in acid rain.
Granite is generally less affected by acid rain than other rocks because its surface is not very reactive. However, if it does become acidic due to precipitation, then it can dissolve in similar ways to limestone.
Fish kill due to acid rain: The main effect that acid rain has on fish is through dissolving their bones, which leaves them vulnerable to further damage from predatory animals. Acidic water can also cause organs such as the gills and skin to soften, which makes them more susceptible to attack from predators. Some species are able to adapt to changing environmental conditions by evolving new characteristics, such as thicker skins for fish to protect them from further harm by acid rain. However, many do not have this chance and die off entirely.
Forests killed by acid rain: Acid rain causes major problems for forests because it destroys the top layer of soil, which contains many nutrients that help plants grow. Without this protective layer, the soil becomes vulnerable to erosion by wind and water.
