Tripura State Pollution Control Board


Air Quality Monitoring is conducted at various monitoring stations in the State and near the polluting clusters of industries. Specific parameters like Oxides of Sulphur, Oxides of Nitrogen, Respirable Particulate Matter, etc. are monitored in the ambient air quality monitoring stations.

List of Available Instruments Used For Air Monitoring:

Sl.No.Name of Instruments
1.Respirable Dust Sampler APM-460 (XNL) with Thermo Electrically Cooled Gaseous Sampling Attachment APM 411 TE.
2.Fine Particulate Sampler APM-550(MFC)
3.Anemometer (Digital)
4.Hygro-Thermo Meter (Digital)

List of Parameters and Methods of Analysis:

5Lead (Pb)AAS method after sampling on EPM Filter paper
6Nickel (Ni)AAS method after sampling on EPM Filter paper
7Arsenic (As)AAS method after sampling on EPM Filter paper

National Air Monitoring Programme

The Tripura State Pollution Control Board is operating 2 (two) nos. of ambient air quality monitoring stations under National Air Monitoring Programme (NAMP) in collaboration with Central Pollution Control Board. The details of two Ambient Air Quality Monitoring Stations along with frequency of monitoring are as follows:
The air pollutants viz. Particulate Matter (PM10), Particulate Matter (PM2.5), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2) have been monitored. The ambient air quality samples were collected as per the standards prescribed by CPCB. The data pertaining to all the ambient air have been uploaded in the Environmental Air Quality Entry System (E-AQ-DES) of the CPCB portal for compilation and preparation of report.

Industrial Air Quality Monitoring

The Board has carried out the Ambient Air Quality Monitoring for industrial units operating in the State. The Ambient Air Quality monitoring has been carried out in various industrial clusters such as Brick Field, Rice Mills, etc. as well as various Industrial Estates.

Ambient Air Quality Monitoring Survey

The Board is regularly conduscting ambient air quaity survey in different areas of the State Capital and District Headquarters on complaint basis. The survey has also been conducted on the festive occassions like Durgapuja, Laxmipuja and Deepawali Festival every yearto assess the impact of Air Quality due to bursting of fire crackers.
