People in Kathmandu valley are experiencing a record high level of pollution with the air quality indicator (AQI) reaching extreme level, on Tuesday.

According to the data obtained from the US Embassy air quality monitor (AQM) located at Phora Durbar, Narayanhiti  measured PM2.5 at 12:00 pm today was 448.

PM2.5 is one of the standards to measure air quality which takes stock of concentration of contaminant matters with a diameter of less than 2.5 micrometers in the environment that can perforate deep into the lungs even when one is wearing facial masks.

These contaminant matters mostly come from smoke emitted by vehicles and factories.

The AQI reached towards the hazardous level with it peaking 606 AQI at 11:00 pm last night. The deteriorating quality of air in Kathmandu Valley is likely to increase the risk of various respiratory diseases.
