AMBIENT AIR QUALITY MONITORING REPORT - FEBRUARY, 2021
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 monitoring conducted during the 3rd and 4th week of February 2021, 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. All the AQI indices are under 'Good' category as per the National AQI category and its associated health impact except for two major towns i.e Rangpo and Deorali (Gangtok) in East Sikkim falling under 'Satisfactory' category which may be attributed to the fact that these two towns are located in proximity to the National Highway NH10 which is subjected to heavy movement to vehicles.
