Delhi pollution levels rise after diwali

Delhi : Air quality in New delhi dipped to ‘hazardous’ levels on Friday after the festival of Diwali was celebrated with the usual widespread use of fireworks, defying a citywide ban.

According to the source of Air Quality Index (AQI), most locations in Delhi were recording an AQI above 500 on Friday morning, with the index maxing out at 999 in a few locations.

The AQI measures the concentration of PM2.5 particulates per cubic meter of air, which in high amounts can cause cardiovascular and respiratory disease.

Accourding to The World Health Organization deems anything above an annual average of 5 micrograms as unsafe — the average reading in Delhi on Friday was 706 micrograms.

Chief minister Arvind Kejriwal issued a ban on firecrackers last month in an effort to control the city’s pollution levels, however Diwali firecracker celebrations on Thursday mostly proceeded as normal and likely worsened the smog.

The AQI stood at 197 on Wednesday morning in delhi but By Friday the AQI was recorded at 492 and classified as ‘hazardous’.

Accourding to India’s government-run System of Air Quality and Weather Forecasting And Research (SAFAR) said pollution levels in Delhi were “severe” and worse than levels recorded in 2020.

SAFAR said , “(In the last 24 hours), PM2.5 level is higher as compared to 2020 but much less than that in 2018but now it leaking at 36% .

New Delhi has been struggling with the issue of poor air quality for years, an issue exacerbated by stubble burning by farmers in nearby regions during the harvest season and the celebration of Diwali with firecrackers.

According to the SAFAR , the pollution would likely lift over the weekend provided no more fireworks were let off, despite the fact that stubble burning was expected to continue.
