Drawbacks: Acid Rain Erosion, Weakness when Bent or Stretched, Some Find it Unattractive, Quarries can be Noisy and Visible. Limestone is a popular building material, but it has some drawbacks. These include: Acid Rain Erosion: Limestone can be chemically weathered by acid rain, resulting in discoloration and pitting.
How does acid precipitation affect marble and limestone …
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive. You might expect …

It devastates aquatic life by disrupting food chains and impairing fish respiration. Similarly, it wreaks havoc on forests by depleting soil nutrients necessary for tree growth. Additionally, acid rain poses risks to human health through inhalation of toxic particles and reduced agricultural productivity.
Acid Rain | U.S. Geological Survey
Acid rain can dissolve certain more soluble elements from the soil, like aluminum. The dissolved aluminum begins to accumulate and can reach toxic levels as it enters local streams and wetlands. Acid rain also removes important nutrients from the soil, such as calcium, potassium, and magnesium. The lack of nutrients can negatively affect …

Acid Rain Lab
Acid rain is a general term that describes how acids fall out of the atmosphere. A better term would be acid deposition, which occurs in two ways: wet and dry. Acid rain, fog, and snow are known as wet deposition. Dry deposition is made up of acid gases and particles, and these constitute about 50% of all acidic fallout from the atmosphere.
