Lockdown: major air pollutants down by at least 50% in Delhi

Apr 07, 2020 16:23 IST

With vehicles off the road and industries shut due to the ongoing lockdown imposed to combat the coronavirus outbreak, the presence of major pollutants in the air -- PM2.5, PM10 and NOx -- has reduced by at least 50 per cent in Delhi. According to an analysis by the central government-run System of Air Quality and Weather Forecasting and Research, in comparison with other cities the highest reduction in these three pollutants have been seen in Delhi. The three pollutants -- PM2.5 which is atmospheric particulate matter that have a diameter of less than 2.5 micrometers), PM10 which atmospheric particulate matter that have a diameter of less than 10 micrometers and NOx which is nitrogen oxide released in traffic emissions -- are some of the most dangerous pollutants and prolonged exposure to these can lead to serious respiratory disorders.
