The Mathura refinery poses problems to the Taj Mahal primarily due to its release of sulfur dioxide and other pollutants that contribute to acid rain. This acid rain corrodes the marble of the Taj Mahal, causing discoloration and damage.
Here’s a more detailed explanation:
Sulphur Dioxide Emissions:
Mathura refinery emits sulphur dioxide as a byproduct of oil refining.
Acid Rain Formation:
When sulphur dioxide reacts with water in the atmosphere, it forms sulphuric acid, which is a major component of acid rain.
Marble Corrosion:
Acid rain attacks the marble of the Taj Mahal, leading to its discoloration and deterioration.
Other Pollutants:
Besides sulphur dioxide, the refinery also releases other pollutants that can further contribute to air pollution and damage to the Taj Mahal.
Taj Trapezium Zone:
In 1982, the Taj Trapezium Zone (TTZ) was established, a 10,400 sq km area around the Taj Mahal where polluting industries were prohibited to mitigate the impact of air pollution.
