Kathmandu once again tops global air pollution index

Kathmandu: Kathmandu Valley continues to top the global list of cities with the worst air quality, according to the Air Quality Index (AQI) measurement taken at 6:15 am on Wednesday. As per the latest data, Kathmandu recorded an AQI of 184, placing it in the “unhealthy” category. Following closely behind are India’s capital, Delhi, with an AQI of 180, and Kampala, Uganda, with 157.

Medical professionals have warned that Kathmandu’s air quality has reached levels that pose serious health risks. Experts attribute the high pollution levels to prolonged dry conditions, which have allowed dust to accumulate in the atmosphere, as well as smoke from wildfires in surrounding forests.

Although pollution levels have slightly decreased over the past few days, Kathmandu remains the most polluted city in the world. Just a few days ago, the Valley recorded an alarming AQI of 352. The Ministry of Health has issued an advisory urging citizens to take precautions, noting that Nepal’s air ranks among the most hazardous globally.

Doctors have advised the public to avoid outdoor activities, especially during the morning and evening hours. According to the World Health Organization (WHO), an AQI below 35 is considered safe for human health, while values between 35 and 50 are still acceptable. However, any reading above 50 begins to pose health risks.
