Delhi air pollution: Delhi continues to grapple with hazardous air pollution as the Air Quality Index (AQI) reaches the "severe plus" category, touching the 500 mark in several areas. The overall AQI spiked to 494, marking one of the worst pollution spells that the city has recorded in the past few years.
According to the Central Pollution Control Board (CPCB), the air quality index in several areas of Delhi, including Anand Vihar, Ashok Vihar, Bawana, Jahangirpuri, and Major Dhyan Chand Stadium, reached 500 on Tuesday morning. 'Severe' air quality can have an adverse effect on both healthy individuals and people who already have medical conditions.
A thick layer of smog has engulfed Delhi, obscuring visibility and creating a hazy atmosphere as the Air Quality Index (AQI) surged to 494, marking the highest level of the season. The strictest restrictions under the Graded Response Action Plan (GRAP) IV are now in effect in the capital. The Supreme Court has directed authorities not to lift the curbs without its permission even if the AQI falls below 450.
