KATHMANDU: Air pollution in the Kathmandu Valley remained at an unhealthy level on Wednesday, with the Air Quality Index (AQI) recorded at 192 by midday, according to the Department of Environment.

The department said pollution levels have shown no significant improvement in recent days. On Sunday, the Valley’s AQI stood at 175, before rising further to 192 on Wednesday.

An AQI reading between 151 and 200 is considered unhealthy, meaning everyone may begin to experience health effects, while members of sensitive groups could face more serious impacts.

Authorities have urged residents, especially children, the elderly and those with respiratory conditions, to take precautions and limit outdoor activities when pollution levels remain high
