Delhi air quality index has worsened in the past few days
New Delhi:
With the air quality index (AQI) in Delhi worsening in the past few days, the Commission for Air Quality Management (CAQM) has invoked stage two of the anti-pollution plan GRAP this morning.
As per the real-time data provided by the System of Air Quality and Weather Forecasting and Research (SAFAR), the AQI in Delhi at 8 am was recorded at 317, which falls under the “very poor” category.
An AQI between 0 and 50 is considered good, 51 and 100 satisfactory, 101 and 200 moderate, 201 and 300 poor, 301 and 400 very poor, 401 and 450 severe, and above 450 severe-plus.
According to a forecast by the India Meteorological Department (IMD), the daily average AQI of Delhi is expected to stay in the ‘very poor’ category in the coming days owing to unfavourable meteorological and climatic conditions.
Under stage two of the GRAP or the Graded Response Action Plan, there will be restrictions on the use of coal and firewood as well as diesel generator sets in the Delhi-National Capital Region (NCR).
