Vehicles ply on the roads of Kathmandu, Nepal, on March 12, 2026, as polluted haze covers the valley, plummeting the Air Quality Index. The city's Air Quality Index ranges between 200 to 250 in the "very unhealthy" category, well above the threshold of 150 that is considered unhealthy and past the 200 mark that signals very unhealthy air. Fine particulate matter, or PM2.5, the most dangerous category of airborne pollutant due to its ability to penetrate deep into the lungs, is recorded at 129.9 micrograms per cubic meter, more than 25 times the World Health Organization's recommended safe limit of 5 ug/m3. Coarse particulate matter, PM10, stands at 100.3 ug/m3. Under Nepal's government-approved Air Quality Index scale, a reading of 0 to 50 is considered good, 51 to 100 moderate, 101 to 150 unhealthy for sensitive groups, 151 to 200 unhealthy, 201 to 300 very unhealthy, and anything above 300 hazardous. The Ministry of Health and Population urges all residents to take precautions. According to the ministry, prolonged exposure to air pollution can cause serious damage to the heart, blood vessels, lungs, eyes, and kidneys, and can contribute to conditions including asthma and cancer.
