Every winter, Delhi's air pollution soars up to a critical level, impacting public health with foul air. This polluted air can be compared to smoking 10-15 cigarettes a day, "Air population has reached alarming levels in Delhi and is causing severe damage to health of citizens. We have to act immediately to control this menace, orwise, health consequences will be disastrous. We are alrey seeing an increasing number of patients in our hospital continuously complain about a cough, irritation in throat and nose," said Dr D.S. Rana, Chairman, Board of Management, Sir Ganga Ram Hospital 

installed artificial lungs were exposed to this very air that transformed in color. From installing at noon on November 3 to noon November 5, artificial lungs turned white to black. 

"I've seen a change in colour of lungs over past 30 years that I've been operating. Earlier I used to see black deposits only in smokers and ors would have pink lungs. But, noways, I only see black lungs. Even teenagers have black spots on ir lungs. This is frightening. With this unique installation, we hope to show people reality of what's happening to ir lungs," said Dr Arvind Kumar, Founder Trustee, Lung Care Foundation, Chairman- Centre for Chest Surgery, Sir Ganga Ram Hospital
