New Delhi: After Diwali, the level of pollution in Delhi’s air has continued to raise concern. In several areas of the capital, the Air Quality Index (AQI) has reached close to the severe level. On Wednesday morning, November 11, people again got no relief from toxic air. AQI was recorded above 400 at some monitoring centres, while in most areas the air remained in the very poor category.
According to available monitoring data, AQI in Burari was recorded at 405, which falls in the severe category. North Campus recorded 376, Chandni Chowk 379 and ITO 367. In Chhawla, the AQI reached 396. However, pollution levels varied across different parts of the capital. According to the Central Pollution Control Board, an AQI between 301 and 400 is considered very poor, while 401 to 500 is classified as severe.
According to experts, smoke from firecrackers during Diwali adds to the pollution already present in the air. In addition, vehicular emissions, industrial smoke, dust from construction work and incidents of stubble burning in neighbouring states are also affecting air quality. Because of slow cold winds and moisture in the atmosphere, pollutant particles can remain suspended in the air for a long time.
In view of rising pollution levels, children, the elderly and people suffering from respiratory or heart-related illnesses need to take special precautions. Experts have appealed to people to avoid outdoor exercise, wear an N-95 mask when necessary and seek medical advice if they experience breathing difficulties.
