The effects of environmental pollution on the Eiffel Tower include damage to the iron structure due to acid rain and the accumulation of pollutants on the surface.
The Eiffel Tower, which is made of iron, has been affected by environmental pollution in several ways. Acid rain is the most significant environmental factor that contributes to the degradation of the Eiffel Tower. When sulfur dioxide and nitrogen oxide gases are emitted into the atmosphere, they combine with water vapor to form sulfuric and nitric acids. These acidic compounds fall back to the earth's surface as acid rain, corroding the iron surface of the Eiffel Tower and causing damage over time.
The acid rain has led to a loss of detail and aesthetic value due to erosion, pitting, and cracking of the metal structure. Additionally, the accumulation of pollution and dirt on the surface of the Eiffel Tower has also contributed to its degradation. As a result of pollution, the Eiffel Tower's once-golden hue has become a dull brown color, and it has become more difficult to maintain the structure's original aesthetic appearance. The Eiffel Tower is now being cleaned regularly to remove pollutants and maintain its structural integrity, but its deterioration remains an ongoing concern.
