Air Quality in the national capital, Delhi is transitioning from poor to worse in no time. The Air Quality Index (AQI) was recorded at 328 on Friday morning which falls under the poor zone. Hence, the Delhi people are waking up to hazy and polluted air. On Thursday, 12th November, the AQI was 314 which is equally poor. Hence, a constant deteriorating air quality index is witnessed.
Air Quality status for the coming days:
The Indian Meteorological Department has officially released this data. However, on Diwali, the already deteriorating AQI is expected to degrade further. Hence, November 14th and 15th in Delhi NCR will witness a major hazy and polluted environment.
Dr. VK Soni, Head of IMD environment and research centers says, “ Air Quality Index will improve post-Diwali and the city might witness little drizzles in coming days. Hence, the AQI with only worsen for tomorrow. However, additional emissions must be regulated to avoid worsening situations.
Why is Air Quality in Delhi getting Bad?
Starting from November 6th, AQI in Delhi kept on degrading and contaminations increased. The sole reason for this is the change in wind speed, the stubble burning and the onset of winter smog. However, increased emissions and Diwali pollution cannot be ignored. Hence, all of this contributes to poor quality. The marginally improved AQI measured on Wednesday, 11th November, was only a short term relief and nothing else.
The System of Air Quality and Weather Forecasting Research(SAFAR) along with the Indian Institute of Tropical Meteorology (IITM) announced a similar forecast for Diwali Week. The forecast said that even on not bursting crackers, the AQI will likely go down from poor to very poor for tomorrow. Hence, the stubble burning is responsible for the unwanted hike in AQI. Therefore, the PM 2.5 level is considered to be at the highest end of the very poor category.
What is good AQI:
0 – 50 Air Quality Index is considered as good. However, 51 – 100 falls under the moderate zone of AQI. 201-300 is considered poor and very poor is beyond 300. However, the severe category that falls in 400 – 500 should be avoided.
