New Delhi: Analysis conducted by air quality systems and weather forecasting (Safar), forecasting under the Ministry of Earth Department, show this year Delhi saw 179 days when PM2.5 concentration was in the standard of national ambient air quality.
Of the 60 micrograms per cubic meter.
Track the level of pollution in your contrast cityin, the standard is filled with only 137 and 121 days in 2019 and 2018.
The highest number of “good air” (193) was recorded in 2020 because the pollution rate was drastically reduced due to locking.
Until December 30 this year, air quality above the standard for 51% of the days.
However, PM2.5 concentration surged into four national standards at almost 12 days.
Gufran Beig, Director of the Founder Project, Safar, said, “Analysis reveals that the number of days when we meet the increasing standards.
Higher counts than such days in 2020 are mainly due to locking.
However, extreme pollution events in the winter continues Severely because the annual average concentration of PM2.5 remains almost unchanged.
“” This analysis is based on the concentration of PM2.5, which still has lead pollutants in Delhi air for 95% from a day of a year, “beig added.
While the level of PM2.5 30 or below is classified as “good”, the concentration between 31 and 60 is included in the “satisfying” category and which between 61 and 90 is classified as “moderate”.
“Poor” PM2.5 concentration ranges from 91 to 120, “very bad” from 121 to 250 and “severe” from 251 and above.
Experts say the focus must be on taking action throughout the year to ensure that all days can meet air quality standards.
Anumite Roychowdhury, Executive Director, Research and Advocacy, Science and Environment Center, said, “This is a good sign that the number of days with the concentration of PM2.5 in a good and satisfying category is increasing.
But Delhi still requires more stringent multi-sector actions to reduce Annual average and basic base pollution By Safar said the air quality might be in the “very poor” category from December 31 to January 2 “Because of temperature and fog predictions, air quality is predicted to remain in a very bad category.
Not expected to touch the severe category in the next three days due to local wind speeds which is relatively higher, “Beig said.
