The Alarming Statistics
New Delhi, once again, has taken the lead with an AQI of 483, closely followed by Lahore at 371. Kolkata and Mumbai are not far behind, registering AQI levels of 206 and 162, respectively. According to experts and medical professionals, a safe AQI for a healthy individual should ideally be less than 50. Unfortunately, these cities are experiencing levels far beyond the recommended limits.

Causes of the Crisis
Officials have attributed this surge in air pollution to a combination of seasonal factors, including low temperatures, stagnant winds, and the burning of agricultural stubble in neighbouring states. These circumstances have led to a dangerous accumulation of pollutants in the atmosphere.

Health Implications
The impact on public health is starkly evident, with numerous residents reporting discomfort, including irritation in the eyes and throats. In some monitoring stations, the AQI has soared to over 550, painting the air a dense grey. An AQI range of 400-500 not only affects healthy individuals but also poses a significant danger to those with pre-existing health conditions.
