The aesthetic appeal of the Taj Mahal is threatened by:
Show answer Hide answer
Answer: B. Air pollution released from oil refinery
Explanation
Industrial oil refineries release corrosive sulfur dioxide and nitrogen oxide emissions nearby. These acidic air pollutants react with atmospheric moisture to form acid rain and fog. Acid deposition severely corrodes and discolors the white marble surface of the Taj Mahal. The Taj Mahal is constructed from high-purity white marble vulnerable to chemical weathering. Industrial air pollution in the region has been a major environmental concern for decades. Acid rain converts calcium carbonate marble into soluble gypsum, degrading delicate stone carvings.
Environmental courts have ordered surrounding industries to adopt pollution controls to protect monuments. Air quality monitoring stations operate continuously around the Taj Mahal to track pollutant levels. Heritage conservation efforts require controlling regional industrial emissions to preserve historical architecture. Option A is incorrect because high ambient temperatures alone do not dissolve marble surfaces. Option C is wrong because riparian river erosion threatens foundations rather than marble aesthetics. Option D is inaccurate because Yamuna water discharge affects aquatic life more than monument marble.
