According to the Air Quality Index (AQI), which measures air quality, the AQI of the Valley is 177. This means an unhealthy air condition. An AQI of 201 to 300 is considered very unhealthy.
Similarly, the Indian capital New Delhi is currently ranked first in the world in terms of air pollution. Its AQI is currently 186.
According to the World Health Organization standards, AQI should be less than 35 for human health. But an AQI of up to 50 is considered normal. An AQI above that is considered unhealthy for human health.
An AQI of 51 to 100 is given a yellow signal or a caution. An AQI of 101 to 150 is understood to affect patients with respiratory and heart diseases, while an AQI of 151 to 200 is considered unhealthy.
An AQI of 201 to 3000 is considered to be very unhealthy, while 301 to 400 is considered hazardous, and 401 to 450 is considered extremely hazardous.
Three days ago, air pollution in Kathmandu was even higher. Since Friday, normal rain and wind have reduced the pollution to a minimum.
According to Gyan Raj Subedi, Director General of the Department of Environment, lack of rainfall, increasing dryness, the tendency to burn agricultural residues, and forest fires have played a major role in increasing air pollution in the country.
