The Agra district administration is also planning to ban use of coal by small industrial units making bangles and famous local sweet - 'petha' to protect the Monument of Love.
"A recent study published in an American journal says that due to brown and black carbon particles, the white marble of the Taj Mahal is turning yellow. Taking note of this, we have banned use of cow dung cakes used for cooking purposes in the city," Divisional Commissioner, Agra, and Chairman Taj Trapezium Zone, Pradeep Bhatnagar told PTI.
Asked about the inconvenience caused to the poor due to ban on burning of cow dung cakes, Bhatnagar said officials have been asked to organise special camps to distribute LPG connections to them.
He said a ban on coal-based 'petha' units in the city and bangle making units in adjoining Firozabad district was also on the cards as these emitted black carbon soot.
