NEW DELHI: The capital’s air quality slipped to the ‘very poor’ category by late Sunday evening, a day before Diwali, prompting to impose stage 2 of the Graded Response Action Plan (Grap). Stage 2 of the plan restricts use of DG sets across and bars interstate buses, other than those running on electricity, CNG or BS-VI diesel, from entering Delhi.
According to forecasts, unfavourable weather conditions and emissions from firecrackers on Diwali are likely to worsen the air quality to ‘severe’ levels by Tuesday.
At 4pm Sunday, the city’s average air quality index (AQI) during the preceding 24 hours stood at 296, in the upper end of the ‘poor’ zone. By 7pm, the AQI had slipped into the ‘very poor’ range at 302. Air quality is likely to worsen to the higher end of ‘very poor’ on the festival day (Monday).
The impact of l emissions due to firecrackers is likely to stay in the air through most of the week, with no respite from extremely toxic air likely until at least Friday, as winds are expected to remain calm, analysts said.
According to the forecast by the Air Quality Early Warning System, further deterioration of air quality to the higher end of the ‘very poor’ category is expected by Diwali day.Get the latest lifestyle updates on Times of India, along with
