India is one of those countries. Around one 130 crores, people had been urged by the government to stay home and to avoid unnecessary travel.
This has significantly reduced the traffic movement across the country. Over 90 cities including Delhi recorded minimal air pollution in the last few days.
Nitrogen oxide pollution can increase the risk of respiratory conditions, it is mainly caused due to high motor vehicle traffic. The level of nitrogen oxide has considerably dropped by 43% in Pune including 30% in Mumbai and 50% in Ahmedabad.

According to the system of air quality and weather forecasting and research, the lockdown has led to a drop in PM 2.5 by 30% in Delhi and by 15% in Ahmedabad and Pune.
