New Delhi (NVI): The air pollution levels have dropped significantly across several cities in the country including National Capital Delhi as the 21-day lockdown for combating COVID-19 has led to reduced vehicles on roads and ban on construction activities.
The positive effect of a limited human interference with the environment was felt on Sunday when the country observed ‘Janta Curfew’.
The national capital witnessed a significant drop in pollution levels on that day as Delhiites remained indoors and almost no vehicles were seen on the roads due to the one-day lockdown.
So we can say that the corona scare has left us with cleaner air as pollutions levels have dropped in some major cities in India including Pune, Mumbai, and Ahmedabad.
According to the pollution data shared by SAFAR, there was a considerable reduction in nitrogen oxide levels in these cities in March 2020.
The System of Air Quality and Weather Forecasting And Research (SAFAR) has also come up with an air quality analysis comparing the 2018 and 2019 data with that of March this year.
Taking the air data with effect from March 5, the analysis says that there was a considerable reduction in Nitrogen Oxide by 45 percent in Pune, 50 percent in Ahmedabad and by 45 percent in Mumbai, as compared to 2018 and 2019.
The SAFAR report further states that in Delhi, no significant change was seen in Nitrogen Oxide (Nox) levels after last week dip but PM 2.5 shows a declining tendency. “However, individual locations in all cities are showing significant changes,” it said.
