Did you know if you are staying in Delhi right now, you are approximately smoking 17 cigarettes worth of air pollution daily? As per Berkeley Earth scientific paper, 1 cigarette is equivalent to inhaling air pollution of 22 µg/m3 for one day. Right now, the AQI of Delhi is above 380 at most places. In some places it goes beyond 400 which translates to 'very poor' and 'severe' category of air quality respectively. Hence, according to the Berkeley study, inhaling Delhi air right now is as hazardous as smoking 17 cigarettes a day
