(Aditya Shaw, Intern Journalist): For nearly a month and a half, the residents of the capital were forced to breathe very bad air on Tuesday after 41 days. At the same time, after a long time, the color of the sky also appeared blue and it was sunny throughout the day. Changes in the direction of the wind, the rains that have taken place in the last few days have helped Delhi get rid of severe category wind and recorded it in the average range with 171 air quality index.
However, in Gurugram included in Delhi-NCR people with a 204 air quality index breathed bad air. The figure was recorded 246 a day earlier. The average air quality index of the capital was recorded at 171 by the Central Pollution Control Board (CPCB) on Tuesday, while it was in a poor category with a figure of 221 a day earlier.
Earlier on October 6, the air quality index was recorded in the average range. After this, the air of Delhi started to deteriorate from October 7, after which the air level in the capital continuously remained in the very poor category to severe category. According to a report, the air standards body of the Ministry of Earth, the winds have shifted to the south-south-western direction at this time as well as the increase in wind speed, which has helped in reducing the pollution elements.
Apart from this, the rains due to the activation of Western Disturbance have also provided relief in reducing pollution in Delhi-NCR. At the same time, there has also been a decrease in more cases of burning of stubble being recorded for the last several days. According to a report, only 98 stubble burning incidents have been reported in the neighboring states of Delhi on Monday. Which accounted for only three percent of the pollution generated PM 2.5.
However, this improvement in wind conditions is not going to last long. From next Wednesday, wind may once again fall into the poor category. In this episode, the air level is expected to remain in the bad category to the very poor category on November 19 and 20. According to travel data, the PM 2.5 level responsible for pollution was recorded at 73.7 micrograms per cubic meter by 5 pm.
At the same time, the PM10 level was 130 micrograms per cubic meter. Whereas the PM10 level is below 100 and the PM2.5 level is less than 60 is considered safe. If their figure exceeds 500, then emergency situations occur. Significantly, this Diwali, the capital had recorded the highest pollution compared to the last four years. The main reason for this was the use of firecrackers and the burning of stubble even after the ban. At the same time, according to a special report released by the CPCB on Sunday, the increase in polluted elements on Diwali this year was also higher than the previous Diwali.
Apart from Delhi, NCR has also improved with the improvement in wind conditions. In this episode, the air levels in Faridabad, Ghaziabad, Greater Noida, and Noida, etc. were average. Whereas in Gurugram people with a poor air quality index of 204 breathed in the bad air. At the same time, the average air quality index of 166 was recorded in Ghaziabad, 172 in Faridabad, 186 in Greater Noida, and 178 in Noida.
