BANGALORE: The Karnataka State Pollution Control Board (KSPCB) is planning to install an online real time monitoring system to check air pollution in 15 districts across the state in a phased manner.The initiative is aimed at identifying and mitigating pollution levels across the state, said Karnataka State Pollution Control Board Chairman A S Sadashiviah. He said, "For the installation of equipment, we are finalising the districts based on the pollution level. In the first phase we will be installing the systems at Bellary, Mangalore, Chitradurga, Belgaum, Gulbarga, Mysore and Tumkur.""The other districts will be finalised later and taken up in the second and third phases depending on the requirement," explained."This system will be in the lines of the two similar systems which are currently functioning at the city railway station and Basveswaranagar at Bangalore," he added.Speaking about the working of the system, Sadashivaiah said, "Analysers for major pollutants like sulphur dioxide (SO2), carbon monoxide (CO), Respirable Suspended Particulate Matter (RSPM) and nitrogen dioxide (NO2) will be installed. All the four analysers will work on different principles and represented pollution content graphically.""Once the major polluting elements and particulates are identified, we can specifically put a check on it. This way we can reduce the level of pollution," the chairman of the Pollution Control Board observed.
