Bad air days have returned to Delhi as the city's air quality continues to deteriorate ahead of Diwali celebrations. According to data from the Central Pollution Control Board (CPCB), Delhi's overall Air Quality Index (AQI) on Friday stood at 254, placing it in the 'poor' category. However, several neighbourhoods considered pollution hotspots have already breached the 300-mark, entering the 'very poor' category.
As per CPCB data, Anand Vihar recorded the highest AQI at 384, followed by Wazirpur (359), Jahangirpuri (307), Bawana (307), and Siri Fort (303). CPCB data also shows that air quality in the national capital began to plummet from October 14 onwards.
Visuals from across the city show a hazy skyline with reduced visibility. Around the Jawaharlal Nehru Stadium area, the AQI stood at 252 as per CPCB readings from the Barapullah Bridge. At Akshardham, the AQI was recorded at 230, while visuals from India Gate showed the index largely remaining in the 'poor' category. In response, truck-mounted water sprinklers have been deployed to curb dust levels.
Experts have raised concerns over the sharp rise in pollution levels. Pulmonologist Dr. Sharad Joshi while speaking to news agency ANI expressed concern for asthma and TB patients, saying, "Air Quality Index (AQI) has risen significantly, leading to higher levels of particulate pollutants from sources like crop burning, vehicular exhaust, and fireworks. This exacerbates respiratory issues for those with pre-existing conditions such as COPD, asthma, and those who have had tuberculosis, leading to increased symptoms like cough, fever, breathlessness, and chest pain... Even those without prior respiratory issues, especially children and the elderly, are at risk due to weakened immunity."
Dr. Joshi further explained, "The use of 'green crackers' during Diwali emit fewer pollutants compared to traditional fireworks but are not entirely harmless... Vehicular exhaust contributes to pollution year-round, but the problem worsens during October and November... To mitigate pollution effects, it is suggested to reduce vehicle use through carpooling, maintain vehicle pollution levels, use air purifiers indoors, ensure proper kitchen ventilation, avoid indoor pollution sources like incense, and for those with respiratory issues, continuing regular medication and considering preventive vaccines. Additionally, wearing N95 or double surgical masks during outdoor activities is advised for everyone to protect against poor air quality."
