Home / Air Quality Monitoring
This webpage was last updated on December 1, 2023
The State Pollution Control Board Sikkim has been conducting ambient air quality monitoring under the National Ambient Air Monitoring Programme
in eight stations in the state of Sikkim. As per the latest AQI monitoring conducted during the year 2023 (January to August), the ambient air
quality in the state has been well within the permissible limits as per the provisions of the Air (Prevention and Control of Pollution) Act, 1981.
While AQI for majority of the towns are under 'Good' category, three major towns i.e Rangpo, Singtam and Deorali (Gangtok) in East Sikkim have fallen under 'Satisfactory' category which may be attributed to the fact
that these towns are located in proximity to the National Highway NH10 which is subjected to heavy movement to vehicles.
