Delhi-NCR is currently grappling with a dire air quality crisis on November 3. The Air Quality Index (AQI) has surpassed the alarming '400' threshold on a 500-point scale in numerous areas, heralding a severe environmental predicament.
Notably, locations like Anand Vihar station, Punjabi Bagh station, and Mundka station have registered AQI levels well above the 400 mark, classifying them in the 'severe' category, according to data released by the Central Pollution Control Board (CPCB). This alarming situation has led to the imposition of a ban on non-essential construction activities and the closure of primary schools in the capital.
In response to the deteriorating air quality, authorities have enforced restrictions on diesel and petrol vehicles operating in and around Delhi.
Government agencies are issuing stern warnings, forecasting a potential exacerbation of the pollution crisis in Delhi-NCR over the coming 15-20 days. This anticipated degradation is attributed to the upsurge in farm fires, a drop in temperature, and reduced air circulation. A thick smog has descended upon the national capital, and it is expected to persist in the days ahead.
The concentration of PM2.5, fine particulate matter known to pose health risks, has exceeded the safe limit of 60 micrograms per cubic meter by seven to eight times at various locations, heightening concerns about respiratory and health complications.
Stubble burning has been identified as a significant contributor, responsible for 25% of the PM2.5 pollution in Delhi on November 2, with the potential to increase to 35%, according to the Indian Institute of Tropical Meteorology in Pune.
