Neighboring Gurugram remains Very Poor with a 392 index reading.Medical experts on Delhi air pollution According to medical experts, healthy individuals should be breathing air with AQI scores under 50. The current levels over 400 times that threshold pose grave threats for those with pulmonary conditions and increase lung cancer risks city-wide.Alarmed by the conditions, Delhi Environment Minister Gopal Rai penned an urgent letter to Union Minister Bhupender Yadav.
