For the past 22 days, pollution has been on an extreme level in Delhi. It came down to the ‘poor’ category and eased the situation a little for Delhiites. The overall Air Quality Index (AQI) came down to 280.
This change was a natural one. The change in direction of the flow of the wind helped Delhi’s Air Quality to come down to the ‘poor’ from the ‘very poor’ category. The condition of pollution in Delhi was considered to be severe and extreme for the last 22 days.
The winds gusting on Sunday were up to 20 kmph and 25 kmph on Monday. According to the officials at the India Meteorological Department, this was the reason for the improvement in the air quality. AQI reading at any given time is an average of previous AQI’s recorded in the last 24 hours. This was the reason why Delhi’s AQI on Sunday was 349 and on Monday was 311 and came under the ‘very poor’ category. Although, it was lower than this.
Other neighbors of Delhi also saw an improvement in Air Quality; Faridabad (279), Ghaziabad (268), Greater Noida (255), Gurgaon (276), and Noida (252). So, let’s tell you how to know which AQI is considered good, bad, or very poor. An AQI ranging from 0 and 50 us considered ‘good’, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”.
According to the Ministry of Earth Sciences’ air quality monitor SAFAR, coming weeks will witness better air quality as transport-level winds are likely to slow down and change direction from northwest to south-southeast on Wednesday.
Although, for the next three days, the air quality will be in the poor category. The Delhi Government allowed the construction and demolition activities on Monday when the air quality improved. This was a huge relief to the workers.
Stubble burning accounted for 3 percent of Delhi’s PM2.5 pollution on Tuesday. The Delhi government on Monday lifted the ban on construction and demolition activities given the improvement in the air quality and the inconvenience caused to workers.
