With air pollution in Kochi city increasing by the year, the State Pollution Control Board (PCB) has decided to set up a continuous (online) ambient air quality monitoring station at Kaloor to check the pollution level.
According to Mythili M S, chief environmental engineer, they are looking for a plot near Kaloor junction to set up the station. “Since there is a delay in setting up a monitoring station in Vyttila, we thought of setting up one in Kaloor as the PCB has found excess of carbon monoxide, sulphur dioxide and nitrogen oxides at both the junctions.
The PCB’s plan to set up a similar station at Vyttila is being delayed as it is yet to get the approval of National Highway Authority of India (NHAI) and Kerala Metro Rail Ltd (KMRL).
“After identifying the land, the devices will be installed with sanction from local authorities,” he said.
According to PCB officials, the estimated cost of purchasing and installing the machine will be around `75 lakh. The station will help officials to scientifically analyse the source of pollution. The analyser that will work round the clock will display the amount of sulphur dioxide, hydrocarbon and carbon monoxide levels. It will also measure meteorological parameters like wind speed, wind direction, temperature, relative humidity and solar radiation.
PCB officials said that air pollution is very high at Vyttila and Kaloor junctions. “The data generated by the stations will be closely monitored if the pollution rate is found to be high, the PCB will recommend the Motor Vehicles Department to take appropriate action, including reduction of traffic flow in the area.
PCB officials said that diesel vehicles and old heavy buses and lorries were major causes of air pollution in the city.
