Delhi residents woke up to a double whammy on Monday morning as sharply deteriorating air quality coincided with a severe cold wave gripping the national capital. The city's air remained firmly in the 'poor' category, posing health risks even as temperatures plunged significantly below the seasonal average.
Chilling Temperatures and Deteriorating Air
The India Meteorological Department (IMD) reported that a intense cold wave has settled over the region. The minimum temperature recorded was a biting 6.5 degrees Celsius, which is a substantial 4.5 degrees below the normal average for this time of year. This harsh cold is predicted to persist and affect isolated areas within Delhi until at least January 6, according to weather officials.
Air Quality Index (AQI) in the 'Poor' Zone
Compounding the discomfort of the cold, the air pollution levels spiked. Data released by the Central Pollution Control Board (CPCB) showed that at 7 AM on January 5, Delhi's overall Air Quality Index (AQI) was recorded at 266. This reading firmly places the capital's air in the 'poor' category as per the government's classification system.
To understand the severity, here is how the AQI scale is categorized:
- An AQI between 201 and 300 is classified as 'Poor'.
- Readings from 301 to 400 are considered 'Very Poor'.
- Any index value between 401 and 500 is deemed 'Severe'.
Health Implications and Current Situation
The combination of cold wave conditions and poor air quality creates a serious public health concern. 'Poor' AQI levels can lead to breathing discomfort for most people on prolonged exposure and may significantly affect those with existing respiratory and heart conditions. Authorities often advise vulnerable groups, including children, the elderly, and those with pre-existing illnesses, to limit outdoor activities during such periods.
The current situation underscores the ongoing environmental challenges faced by Delhi, especially during the winter months when meteorological conditions like low wind speed and temperature inversions trap pollutants close to the ground. Citizens are urged to stay updated with official advisories from the IMD and CPCB and take necessary precautions for their health and well-being.
