Kolkata: City can now get a strong picture with the surrounding air quality with 10 new ambient ambient air quality monitoring stations based on sensors (CAAQMS) that provide real-time air quality data throughout the extent and the breadth of kolkata, regardless of the seven existing caaqms.
In addition, 10 sensor-based stations will appear at the pollution hotspots identified throughout the city in March this year.
Among new spots, the skin complex (BANDAL), the Barrackpore police commissioner office, Sector V and Vivekananda Women’s College (Behala Chowrasta) recorded poor air quality on Friday while the rest recorded moderate air quality.
According to the Chairman of the WBPCB Kalyan Rudra, “the sensor is calibrated regularly to the reference level monitor and is being used for air quality management for the city and other countries.
Data represents a broad trend of air pollution in the region.” Apart from the Seven Caaqms – in Ballygunge, Jadavpur , Rabindra Sarobar, Victoria Memorial, Fort William, Campus Rabindra Bharati (BT Road) and Salt Lake – 10 new stations cover several important areas where pollution is considered higher than in its entire city.
“We are now analyzing data to identify air pollution sources to adopt appropriate improvement measures,” said a Senior PCB scientist.
Data from 17 stations provides a clearer picture of air quality around the city.
“For example, the V Sector, Hub IT City, is often found to have ‘poor’ air quality even though there is a lake nearby.
However, we tried to analyze the density of regional vehicles, which was much higher throughout the day.
Behala Chowrasta is another polluted zone because of the density The vehicle and construction of the Metro corridor.
Air quality in the skin complex, for example, remains bad most of the time.
Dumping land is probably one reason.
“But, we may need to investigate whether the pollution control device in the skin unit works properly,” said the source.
All of these caaqms are arranged after the Green Green Tribunal (NGT) mandate, the next 10 CAAQMS-based sensor will appear at pollution hotspots, such as landfill sites, Mega real estate projects, metro corridors under construction, hospitals and zones Sensitive.
“We have talked to KMC, which will give us the appropriate site to prepare monitoring stations.
Unlike conventional CAAQMS, this sensor-based station saves costs and requires less space, “said an official WBPCB.
