Delhi Pollution Alert: AQI Surpasses 400 Despite Cloud Seeding Efforts
Delhi's air quality sharply deteriorated on October 30, 2025, with the AQI crossing 400 in multiple areas, marking the season's worst pollution. Cloud seeding trials intended to improve conditions failed, resulting in persistent heavy smog and hazardous air levels. Experts warn that exposure to such pollution substantially increases health risks, especially strokes linked to PM2.5 particles.
On October 30, 2025, Delhi experienced a significant surge in air pollution, with the Air Quality Index (AQI) exceeding 400 at several monitoring stations like Anand Vihar and Jahangirpuri. The sustained smog created a 'very poor' to 'hazardous' air quality condition across the city. Despite ongoing cloud seeding trials meant to alleviate pollution, the efforts were ineffective, and the air quality continued to worsen. The Central Pollution Control Board recorded AQI figures as high as 408, with most stations reporting values well above 350, which classifies as very poor air quality. The heavy pollution has major health implications; experts highlighted an increased risk of strokes due to prolonged exposure to fine particulate matter (PM2.5), which measures many times above the safe limits recommended by the World Health Organization. Vulnerable populations, including those with pre-existing conditions such as diabetes and heart disease, face heightened risks. The worsening air quality not only impacts Delhi but also neighboring regions like Gurgaon, Ghaziabad, and Noida, which also reported alarming pollution levels. The situation underscores the urgent need for effective pollution control measures beyond cloud seeding to protect public health and environment.
