Why is the Taj Mahal gradually turning yellow? The real scientific truth behind it.
Taj Mahal Dheere-Dheere Peela Kyun Pad Raha Hai? Iske Peeche Ka Asli Vaigyanik Sach Introduction Taj Mahal, jo kabhi chamakdar safed sangmarmar se bana tha, ab dheere-dheere peela aur kuch jagah brown-black pad raha hai. Ye sirf “purana ho gaya” wali baat nahi hai — ye ek clear scientific process hai jiska naam hai acid rain aur sulfation . Agra ke aas-paas ki industries, vehicles, Mathura refinery aur dusre pollution sources ne hawa mein sulfur dioxide (SO₂) aur nitrogen oxides (NOₓ) badha diye hain. Ye gases moisture ke saath react karke sulfuric acid aur nitric acid banati hain, jo phir acid rain ke form mein Taj ke marble par girte hain. Result? Marble ka surface yellow, chalky aur weak ho raha hai — jise scientists “ marble cancer ” bhi kehte hain. The Real Science Behind the Yellowing Marble Composition Taj Mahal mainly calcium carbonate (CaCO₃) se bana hai, jo pure white marble ka basic chemical structure hai. Jab ye calcium carbonate a...
