The Air Quality of Delhi NCR and other cities in India is worsening day by day. The Government, Supreme Court and National Green Tribunal has taken several steps to curb the pollution like banning diesel SUVs, converting all taxies to CNG, increasing green tax on polluting vehicles etc. but still the air quality of the city is far behind the WHO standards. The second edition of Air-O- Thon will focus on the evaluation on these steps and the awareness status of people. The expert panel in the conference will discuss Indoor and outdoor air quality and its threatening effects on health. The panel will also evaluate the various technology and innovation which can help to improve the air quality and minimize the associated risk on individual health.
