Even After Ban On Firecrackers By Supreme Court, Dehli’s Air Quality Remains The Same No Change

Delhi and the National Capital Region woke up to a blanket of smog on Friday, after a quiet and promising Diwali evening gave bursting of firecrackers till late night on Thursday, despite a Supreme Court ban on their sale in the NCR.

The online indicators of the pollution monitoring stations in the city glowed red, indicating a ‘very poor’ air quality as the volume of ultra fine particulates PM2.5 and PM10, which enter the respiratory system and manage to reach the bloodstream, sharply rose from around 7 pm on Thursday.

But as the festivities picked up, the faint echos of crackers started growing louder.

According to the SAFAR (System of Air Quality and Weather Forecasting And Research), the 24-hour rolling average of PM2.5 and PM10 were 154 and 256 micrograms per cubic metre respectively at around 11 pm yesterday.

It has forecast that the pollution levels will peak between 11 pm and 3 am.

The Supreme Court-appointed Environment Pollution Prevention and Control Authority (EPCA) is empowered to enforce the Graded Response Action Plan (GRAP) to combat air pollution in Delhi-NCR.

Measures under the GRAP’s ‘very poor’ and ‘severe’ categories, which include a ban on diesel generator sets, came into effect on October 17 and they will remain in force till March 15.
