Supreme Court's ban on the sale of firecrackers made Diwali a comparatively quiet affair in the Delhi NCR this year.
However, the order did little to help keep the pollution levels in control. According to NDTV, data from the Central Pollution Control Board reflected Delhi's Air Quality Index (AQI) value at 319, putting it in the "very poor" category. Some areas in the city recorded a steep hike in pollution levels with more than 24 times the average level.
As per the indicators of pollution monitoring systems, on Friday morning Delhi's RK Puram monitoring station recorded PM2.5 and PM10 at 878, which is quite hazardous.
But in comparison to last year, pollution levels this year seems much lower. In 2016, the day after Diwali, the Air Quality Index was recorded at 431, as compared to 319 this year.
In 2016, particulate matter (PM)10 and PM2.5 was recorded at over eight times the safe limit. This year, however, PM10 and PM2.5 levels were over two and half times the satisfactory limit.
Several news agencies and people from the city have been tweeting images of smog and pollution from Friday morning.
