PM 2.5 reading between 75 and 168 recorded on Friday 

KATHMANDU, Jan 22: Air quality in Nepal’s capital city, Kathmandu, continued to deteriorate on Friday as well. According to the data collected from various pollution monitoring stations installed at 17 different places in the Valley, dust particles in the air were measured high (168.28 μg/m³) in the morning between 8 and 9. 

The air quality in the country’s most densely populated city improved in the afternoon with a PM 2.5 reading of 76.61  μg/m³ between 1 and 2 as comparatively less number of vehicles plied Kathmandu streets due to mass gathering and rallies organized by a dissident faction of the ruling Nepal Communist Party. 

In comparison to the WHO-set standard of 25 μg/m³ and Nepal government-set guidelines of 40 μg/m³, Kathmandu air is hugely detrimental to human health.
