Kathmandu: Kathmandu Valley’s air quality has deteriorated to a very unhealthy level, with the Air Quality Index (AQI) hovering around 260 throughout the day on Thursday.
According to IQAir, a global air quality monitoring agency, Kathmandu ranked as the most polluted city in the world today. An AQI reading above 200 is considered hazardous for all population groups.
While weather conditions remain clear in most parts of the country, Kathmandu’s atmosphere is filled with smoke, dust, and pollutants, preventing sunlight from penetrating effectively. Meteorologists warn that the toxic air is causing eye irritation, throat discomfort, and respiratory issues among residents.
Air quality expert Dr. Bhupendra Das attributes the worsening pollution to an increase in wildfires, agricultural residue burning in rural areas, and heavy vehicular emissions. Additionally, Kathmandu’s bowl-shaped geography traps polluted air, preventing pollutants from dispersing.
Experts suggest that rain or strong winds are necessary to clear the pollution. However, the Meteorological Department has stated that there is no immediate likelihood of rainfall or stormy weather.
